1999 Corvette Overview

From its inception in 1953, the Chevy Corvette has always been recognized as a vehicle that was a “step above the common car. Beginning with its earliest Motorama concept, to its first production models and beyond, the Corvette quickly became recognized and universally accepted as “America’s sports car” and, over time, became increasingly synonymous with the American dream – a dream in which every American could aspire to own a house, have 2.5 kids, and afford a sporty, two-seat, convertible coupe.

Even as it evolved thru the 1960’s and 1970’s, Corvette had remained an obtainable dream for many, though, as technology evolved and the cars became more sophisticated, more powerful, and, well, more sporty, so too did the price tag for the cars increase. Over time, the Corvette became a luxury item that fewer and fewer enthusiasts could readily afford to purchase.  While this helped add an aura of exclusivity to the car, it also caused some within the General Motors corporation to question whether the Corvette franchise was headed down a path where increasing exclusivity might actually bring about an even greater decline in sales.

It was from this concern that actions were put into motion during the early planning phases of the C5 Corvette.  Chevrolet had begun exploring the idea of creating a less-expensive, somewhat-stripped down variant of the C5 coupe that could be marketed as a “budget-conscious” Corvette.  This lower-cost “stipped” model would feature fewer amenities than its coupe and convertible counterparts.  Early considerations included offering manual windows, cloth seats (versus the standard leather available on the other variants of the car), and even smaller wheels and tires.

1999 Hardtop Chevrolet Corvette
The 1999 Hardtop Chevrolet Corvette (FRC or “Fixed Roof Coupe”)

During the course of the C5’s development, a few prototypes were manufactured that represented this “no-frills” version of the very successful C5 Corvette.  Surprisingly, when these cars were submitted to GM research clinics and shared with potential customers in test markets, the overall response to this new Corvette was fairly negative.  While a few responded that there was a market for a budget-oriented Corvette, most agreed that developing a “cheaper” version of the very successful C5 would not only hurt sales of the other, more expensive variants, but It would also adversely impact the public’s perception of the Corvette.  It seemed that the exclusivity of Corvette ownership that many within GM feared would hurt sales numbers was actually the thing that helped promote them.

Despite this revelation about their flagship automobile, the concept of producing a “stripped-down” Corvette continued to be an appealing idea for the car’s development and marketing managers.  While sales campaigns would have to be selectively tailored to properly reflect the added benefit of purchasing a no-frills Corvette, it was decided that, for the 1999 model year, Chevrolet would move forward with a new variant of the Corvette – one that would focus on eliminating otherwise “unnecessary” features in favor of producing a performance-enhanced, reduced-weight vehicle.  It was with this notion that the C5 hardtop Corvette was born.

1999 Corvette Hardtop Coupe
The 1999 Hardtop Coupe included an external trunk.

What would come to be known as the FRC Corvette (Fixed Roof Coupe), the 1999 hardtop was essentially a convertible with a fixed fiberglass roof.  As was indicated during development, the FRC Corvette was cast as a Corvette for serious performance enthusiasts – and there was some truth to this marketing approach.  The hardtop’s stockier construction made the car’s body 12 percent more rigid than the Coupe (even with the Coupe’s targa top in place).

Additionally, this new variant weighed approximately 92 pounds less than the coupe.  This small, but significant, weight reduction combined with the stiffer overall structure of the body, did make the FRC more appealing to performance enthusiasts.  What’s more, the FRC retained the convertible’s external trunk – a feature that many found both useful and appealing.

While GM’s marketing group was selective in advertising the FRC as a “less expensive” variant of the Corvette coupe, it actually was – although only be $394.00.  While the price difference was not significant, it still offered a certain appeal, especially given the fact that the hardtop coupe still included the same 345 horsepower LS1 small-block V-8 engine.  It was also fitted with the same six-speed manual transmission offered with both the coupe and convertible.  While an optional upgrade on the other Corvettes, the six-speed gearbox was the only transmission available for the FRC, and was generally considered to be another price savings benefit when purchasing the hardtop.  Afterall, the coupe and the convertible were only available with a six-speed when it was purchased as an upgrade (at an additional cost).  Another included option was the Z51 Performance Handling suspension which was otherwise an $1165.00 option upgrade on the coupe and convertible.

There were limitations to purchasing the FRC Corvette.  First, the color choices were far more limited than on the other variants.  The only exterior color options available when ordering a hardtop were blue, pewter, red and white.  Moreover, only the base black leather seats were available, and these came installed without any power adjustments.  Whether actually a cost savings approach or a genuine weight reducing decision, it was marketed as the latter.  In addition to the seat motors, other weight increasing options were unavailable on the hardtop including Real-Time Damping suspension and a number of comfort-and convenience items.

Despite these limitations, the overall response to the hardtop Corvette was generally favorable, though the increased performance aspects of the FRC were debatable at best.   In an automotive review performed by Car and Driver magazine, the hardtop’s 0-60 time was compared to that of the coupe, and the difference was 1/10th of a second between the coupe, which made the run in 4.9 seconds, and the hardtop which did in 4.8 seconds.  The same was true for the quarter mile times with the coupe running the quarter mile in 13.3 seconds at a speed of 109 miles per hour compared to the hardtop running it in 13.2 seconds at a speed of 110 miles per hour.    Additional tests demonstrated that the hardtop’s exterior was actually somewhat less aerodynamic than the targa coupe, resulting in a slightly lower top speed of 169 miles per hour to the coupe’s 171 miles per hour.  However, even given the marginal variances between the two cars, Chevy still managed to sell 4,031 hardtops during the 1999 model year – a number that was considered respectable enough by GM to continue production of the FRC for a second year.

 1999 Corvette
The 1999 Corvette featured a Heads-Up-Display (HUD) that allowed drivers to view speed (and other features) without taking their eyes off the road.

While the hardtop coupe was certainly a major focus of the 1999 model year, there were also a considerable number of new features presented for the targa-top coupe and convertible as well.

One of the most exciting new features offered in 1999 was the “Heads-Up Display” (RPO UV8), a sophisticated and high-tech system that projected the instrument cluster readouts onto the windshield so that the driver could view a compliment of readings – from speed to engine RPMs – without taking their eyes off of the road.  The display appeared in the lower left-hand area of the windshield, right in line with the driver’s line-of-sight.  The display was customizable and included a “check gauges” warning that would indicate when drivers needed to pay attention to a dashboard gauge that was not included as part of the heads up display.  A relatively inexpensive option at $375.00, it quickly became a highly desirable option and was included on a number of 1999 coupes and convertibles.

Another convenience option that was made available on the coupes and convertibles was a Telescoping Steering Column (RPO N37) for an additional $350.00.  This option offered drivers the ability to automatically extend or retract the steering column 20 millimeters of travel in either direction.  This option operated independently of the standard tilt-steering wheel function which remained a manual operation controlled by engaging/disengaging a small lever located on the steering column.  Also returning as an optional upgrade for the coupe and convertible were the Magnesium Wheels option (RPO N73) at an extra cost of $3,000.00.  Lastly, automatic-engaging “Twilight Sentinel” headlamps (RPO T82) were offered, though neither these, the Magnesium Wheels nor the Telescoping Steering Column were made available when ordering a hardtop/fixed roof coupe.

All three variants of the 1999 C5 Corvette received modifications to the car’s magnetically variable power-steering system, which was implemented to make steering more sensitive and reduced the tendency for the car to “wander” when traveling at highway speeds.  Other modifications for all 1999 variants included the introduction of a “next-generation” airbag system that deployed with less force than earlier versions, thereby reducing the severity of airbag-induced injuries sustained in collisions during deployment.

1999 Corvette lineup
The 1999 Corvette lineup included the Coupe, the Convertible and the Hard Top/Fixed Roof Coupe.

Total sales of the 1999 Corvette increased from the previous model year by more than two-thousand units, totaling 33,270 Corvettes in all.  The Hardtop Coupe (FRC) Corvette certainly helped in this department, accounting for 4,031 of the total Corvettes sold that year.  Priced at $38,197.00, the hardtop was certainly the least expensive of the Corvettes that year, though only by a few hundred dollars.  For 1999, coupes sold for $38,591.00 and the convertible sold for $44,999.00.  While Chevrolet’s focus continued to be to increase total units sold, 1999’s production run was certainly respectable – and promising that the Corvette’s long-term future looked increasingly optimistic.

1999 C5-R Race Car
The 1999 model year saw the return of a race-variant Corvette, the C5-R Race Car.

In fact, recognizing Corvette’s successes over the past three years, Chevrolet decided it was time for the Corvette to return to factory backed racing, from which it had been absent since the early 1960’s.  Competing as a production-based sports car, the new C5-R Corvette was developed to compete as a GTS-class race car that maintained the integrity of the production Corvette and shared a number of standard-issue components with it.  These included the stock Corvette frame, engine block, windshield, taillights and marker lights, power steering pump, steering rack, alternator, water pump, and assorted suspension components.  Despite these similarities, the C5-R was approximately four inches wider, had a body produced of carbon-fiber that as only loosely based on the production C5’s body, and featured an engine that produced an additional 255 horsepower over the stock Corvette.

Still, the development of the C5-R race car was a significant milestone for Chevrolet.  It declared unequivocally that the Corvette had found a renewed momentum – both in commercial sales and on the racetrack.  At long last, after years of hardship and dwindling sales, America’s legendary sport car was thriving.

1999 Corvette Common Issues

The following list of common issues is intended for individual reference only, and may not reflect the specific issues of every 1999 Corvette. While the intent of this page is to identify the common issues pertaining to the 1999 Corvette, it is not an all-inclusive list and should be used for reference only.

Mechanical Issues

Leaking Battery

Many C5’s came with AC Delco Freedom batteries that had a tendency to experience exterior cracking near the battery posts. The leaking battery acid drips down the side of the battery, down the funnel-like battery support, straight down onto the PCM and the wiring loom. It can also get onto the A/C lines. In some instances, car crippling damage can occur. Worst case scenario can result in the need to replace the battery, the PCM, and the wiring harness. Additionally, acid corrosion will need to be removed from the frame and the frame repainted to avoid further damage as a result of prolonged exposure to natural elements. In some instances, repairs will need to be made to the air condition lines. It may also require replacing the computer.

Engine

The needle bearings in the OEM rockers have been known to fail. The most common indicators that the engine is experiencing this type of a problem is increased valve train noise and the appearance of needle bearings on a magnetic oil pan drain plug.

Manual Transmission

On manual transmission cars equipped with either an MN6 or M12 transmission, the transmission sounds as if it is chattering/rattling whenever the car begins to accelerate from a complete stop. Despite the foreign nature of the sound, It is completely normal. The sound is the bi-product of the clutch throwout bearing, which creates a ratting sound whenever it is engaged/disengaged. In some instances, the transmission will make a similar, discernable rattling sound when the Corvette ignition is turned on/off. The source of the sound is the same. By depressing the clutch when turning the car on or off, the sound can be eliminated.

The C5 Corvette’s manual transmission shifter can be difficult to get into gear. During normal vehicle operation, it is worth noting that if the shifter is not fully engaged when operating 1st gear or Reverse, it will cause the transmission to literally “pop” out of gear when the clutch is let out. This is not considered the fault of the car by Genera Motors, but the fault of the driver.

Fuel Pump

In all C5 Corvettes, there are two fuel tanks and two fuel pumps. The first fuel pump continually pumps gasoline from the passenger side tank into the driver side tank. This pump is not known to create any type of audible sound. The main fuel pump, which resides directly behind the drivers seat, creates a considerable amount of noise, especially on early model C5 Corvettes. These sounds are normal, and are not an indicator of a failing fuel pump. NOTE: Chevrolet does have a bulletin out instructing Corvette owners how to better insulate against the humming sound of the fuel pump. Additionally, a newer, quieter fuel pump can also be installed.

Braking System

The front brakes of many C5 Corvettes have been known to pulsate during braking conditions. This is the result of warped rotors. The brake rotors developed for the C5 Corvette are known to warp from excessive braking conditions. This does not indicate that the brake rotors require replacement. In many instances, the rotors can simply be turned. However, when inspecting the brake rotors, it is important to observe if the rotors are cracked, as a cracked rotor will require replacement. Cracked rotors are the result of excessive hard braking and could be an indicator of how the car has been driven/maintained.

Exterior Issues

Headlight Bezel Plugs

Old-style headlight bezel plugs, which conceal the bezel mounting hardware, have a tendency to fall off of older C5 Corvettes. To resolve this issue, General Motors released a new style plug that features a twist-lock to prevent the plugs from falling out, but these plugs also require a new headlight bezel. Only the newer style bezels and plugs are available through General Motors and both are compatible with all years of the C5 Corvette.

Hood Rattles

During periods of cold weather, the rubber hood stops have a tendency to rub and chatter against the hood. Proper adjustment and lubrication of the hood stops is known to reduce/eliminate this issue.

Interior Issues

Steering Column

All C5 Corvettes, especially those equipped with a manual transmission, are known to have as have an issue with the steering column locking after ignition is disengaged and remaining locked after vehicle operator starts the vehicle again. In rare instances, it has also been reported that the steering column has locked during vehicle operation. Chevrolet dealerships are able to disable the locking mechanism by replacing the current locking plate with a modified locking plate. At present, this is the only known method to resolve this issue.

Seats

The C5 Corvette seats have several known issues that can occur if improper use and or improper maintenance occurs. Sliding hard across the bolster (the raised/contoured sections of the sitting area on either side of the central seat pad) can break it, causing it to flap from side to side. This area is also the most common area of the seats to experience leather wear/tearing as a result of having the most abrasive contact with the occupant as they enter/exit the vehicle.

The wire springs in the seat bottom, and the bars in the bolsters are sometimes known to wear thru the foam and leather. This situation can be fixed by placing a layer of burlap between the springs and the foam padding.

Another common seat issue often identified with many early C5 Corvettes is that both the driver and passenger seats tend to rock back and forth by about a 1/4″ during hard acceleration and braking. This issue can be repaired, but is not currently identified as an actual issue with General Motors.

Removable Roof

Many C5 Corvette Coupes with the removable roof tend to create a fair amount of wind noise and creaking during normal vehicle operation. While there is no known solution to completely eliminate the wind noise, the creaking can be reduced/eliminated by adding a lubricant to the weatherstriping seal around the roof. A dielectric or petroleum based grease is recommended and will doubly protect the weatherstrip by keeping it from drying out.

Fuel Gauge

In certain instances, some types of gasoline (especially those with a high sulfur content) will cause the fuel gauge to falsely read empty. In some instances, running a fuel system cleaner through the gas tank has been known to resolve this issue.


1999 Corvette Maintenance Schedule

Engine Oil Scheduled Maintenance

Change engine oil and filter as indicated by the GM Oil Life System (or every 12 months, whichever occurs first). Reset the system. The system will show you when to change the oil – usually between 3,000 miles (5,000 km) and 10,000 miles (16,000 km) since your last oil change. Under severe conditions, the indicator may come on before 3,000 miles (5,000 km). Never drive your vehicle more than 10,000 miles (16,000 km) or 12 months without an oil and filter change. Use engine oil meeting the GM Standard GM4718M.

The GM Oil Life System won’t detect dust in the oil. So if you drive in a dusty area, be sure to change your oil and filter every 3,000 miles (5,000 km) or sooner if the CHANGE OIL SOON message appears. Remember to reset the Oil Life Monitor when the oil and filter have been changed. See “GM Oil Life System” (at the bottom of this page) for more information on resetting the system.

Scheduled Maintenance

Every 15,000 Miles (25,000 Kilometers)

Inspect air cleaner filter if you are driving in dusty conditions. Replace filter if necessary.

Every 30,000 Miles (50,000 Kilometers)

  • In heavy city traffic where the outside temperature regularly reaches 90F (32C) or higher.
  • In hilly or mountainous terrain.
  • Uses such as high performance operation.

If you do not use your vehicle under any of these conditions, change the fluid and filter at 100,000 miles (166 000 km). Manual transmission fluid doesn’t require change.

Every 60,000 Miles (100,000 Kilometers):

Replace air cleaner filter and inspect engine accessory drive belt.

  • In heavy city traffic where the outside temperature regularly reaches 90F (32C) or higher.
  • In hilly or mountainous terrain.
  • Uses such as high performance operation.

Manual transmission fluid doesn’t require change.

NOTE: If you haven’t used your vehicle under severe conditions listed previously and, therefore, haven’t changed your automatic transmission fluid, change both the fluid and filter. Manual transmission fluid doesn’t require change.

Every 150,000 Miles (240,000 Kilometers):

Drain, flush and refill the cooling system (or every 60 months since last service, whichever occurs first). See “Engine Coolant” in the “1997 Corvette Fluids/Lubricants” chart (in the right margin of this page) for what to use.

NOTE: It is important for you or a service station attendant to perform these underhood checks at each fuel fill.

Engine Oil Level Check: Check the engine oil level and add the proper oil if necessary.

Engine Coolant Level Check: Check the engine coolant level and add DEX-COOL coolant mixture if necessary.

Windshield Washer Fluid Level Check: Check the windshield washer fluid level in the windshield washer tank and add the proper fluid if necessary.

At Least Once a Month

Tire Inflation Check: Make sure tires are inflated to the correct pressures.
Cassette Deck Service (if so equipped): Clean cassette deck. Cleaning should be done every 50 hours of tape play.
Power Antenna Service: Clean power antenna mast.

At Least Twice A Year

Restraint System Check: Make sure the safety belt reminder light and all your belts, buckles, latch plates, retractors and anchorages are working properly. Look for any other loose or damaged safety belt system parts. If you see anything that might keep a safety belt system from doing its job, have it repaired. Have any torn or frayed safety belts replaced. Also look for any opened or broken air bag coverings, and have them repaired or replaced. (The air bag system does not need regular maintenance.)

Wiper Blade Check: Inspect wiper blades for wear or cracking. Replace blade inserts that appear worn or damaged or that streak or miss areas of the windshield.

Weatherstrip Lubrication: Silicone grease on weatherstrips will make them last longer, seal better, and not stick or squeak. Apply silicone grease with a clean cloth. During very cold, damp weather more frequent application may be required. (See “Recommended Fluids and Lubricants” in the right margin of this page).

Manual Transmission Check (if so equipped):  Check the transmission fluid level; add if needed. (See “Manual Transmission Fluid” in the right margin of this page). Check for leaks. A fluid leak is the only reason for fluid loss. Have the system inspected and repaired if needed.

Automatic Transmission Visual Inspection: It is not necessary to check the transmission fluid level during a visual inspection of the actual transmission. A transmission fluid leak is the only reason for fluid loss. Check for leaks. If a leak occurs, take the vehicle to your Chevrolet dealership service department and have it repaired as soon as possible.

At Least Once A Year

Key Lock Cylinder Service: Lubricate the key lock cylinders.

Body Lubrication Service: Lubricate all body door hinges. Also lubricate all hinges and latches, including those for the hood, rear compartment, console door and any folding seat hardware. More frequent lubrication may be required when exposed to a corrosive environment.

Starter Switch Check:  CAUTION: When you are doing this check, the vehicle could move suddenly. If it does, you or others could be injured. Before you start, be sure you have enough room around the vehicle. Firmly apply the parking brake and the regular brake.

On automatic transmission vehicles, try to start the engine in each gear. The starter should work only in PARK (P) orNEUTRAL (N). If the starter works in any other position, your vehicle needs service.

On manual transmission vehicles, put the shift lever in NEUTRAL (N), push the clutch down halfway and try to start the engine. The starter should work only when the clutch is pushed down all the way to the floor. If the starter works when the clutch isn’t pushed all the way down, your vehicle needs service.

Automatic Transmission Shift Lock Control System Check: CAUTION: When you are doing this check, the vehicle could move suddenly. If it does, you or others could be injured. Before you start, be sure you have enough room around the vehicle. It should be parked on a level surface. Firmly apply the parking brake. (NOTE: Be prepared to apply the parking brake immediately if the vehicle begins to move.)

With the engine off, turn the key to the ON position, but don’t start the engine. Without applying the regular brake, try to move the shift lever out of PARK (P) with normal effort. If the shift lever moves out of PARK (P), your vehicle needs service.

Ignition Automatic Transmission Lock Check: While parked, and with the parking brake set, try to turn the ignition key to OFF in each shift lever position. The key should turn to OFF only when the shift lever is in PARK (P).

On all vehicles, the key should come out only in OFF. Parking Brake and Automatic Transmission PARK (P) Mechanism Check: CAUTION: When you are doing this check, your vehicle could begin to move. You or others could be injured and property could be damaged. Make sure there is room in front of your vehicle in case it begins to roll. Be ready to apply the regular brake at once should the vehicle begin to move.

Park on a fairly steep hill, with the vehicle facing downhill. Keeping your foot on the regular brake, set the parking brake.

To check the parking brake’s holding ability: With the engine running and transmission in NEUTRAL (N), slowly remove foot pressure from the regular brake pedal. Do this until the vehicle is held by the parking brake only.

To check the PARK (P) mechanism’s holding ability: With the engine running, shift to PARK (P). Then release the parking brake followed by the regular brake

Underbody Flushing Service: At least every spring, use plain water to flush any corrosive materials from the underbody. Take care to clean thoroughly any areas where mud and other debris can collect.

Dealership Inspection & Service Items

At Least Twice A Year

Steering and Suspension Inspection: Inspect the front and rear suspension and steering system for damaged, loose or missing parts, signs of wear or lack of lubrication. Inspect the power steering lines and hoses for proper hook-up, binding, leaks, cracks, chafing, etc.

Tire and Wheel Inspection: Inspect the tires for uneven wear or damage. If there is irregular or premature wear, check the wheel alignment. Inspect for damaged wheels.

Exhaust System Inspection: Inspect the complete exhaust system. Inspect the body near the exhaust system. Look for broken, damaged, missing or out-of-position parts as well as open seams, holes, loose connections or other conditions which could cause a heat build-up in the floor pan or could let exhaust fumes into the vehicle.

Engine Cooling System Inspection: Inspect the hoses and have them replaced if they are cracked, swollen or deteriorated. Inspect all pipes, fittings and clamps; replace as needed. Clean the outside of the radiator and air conditioning condenser. To help ensure proper operation, a pressure test of the cooling system and pressure cap is recommended at least once a year.

Rear Axle Service: Check the gear lubricant level in the rear axle and add if needed. A fluid loss may indicate a problem. Check the axle and repair it if needed.

Brake System Inspection: Inspect the complete system. Inspect brake lines and hoses for proper hook-up, binding, leaks, cracks, chafing, etc. Inspect disc brake pads for wear and rotors for surface condition. Inspect other brake parts, including calipers, parking brake, etc. You may need to have your brakes inspected more often if your driving habits or conditions result in frequent braking.

GM Oil Life System

Your vehicle has a computer that lets you know when to change your engine oil. This is not based on mileage, but on engine revolutions and engine operating temperature. When the computer has calculated that the oil needs changing, the GM Oil Life System will indicate that a change is necessary. The mileage between oil changes will vary depending on how you drive your vehicle — usually between 3,000 miles (5 000 km) and 10,000 miles (16 000 km) since your last oil and filter change. Under severe conditions, the system may come on before 3,000 miles (5 000 km). Never drive your vehicle more than 10,000 miles (16 000 km) or 12 months (whichever occurs first) without an oil change. Use engine oil meeting the GM Standard GM4718M.

The system won’t detect dust in the oil. So, if you drive in a dusty area, be sure to change your oil and filter every 3,000 miles (5 000 km) or sooner if the CHANGE OIL SOON message appears. Remember to reset the system whenever the oil is changed.

How to Reset the Change Oil Soon Message

To reset the CHANGE OIL SOON message after an oil change, do the following:
1. Turn the ignition to ON and with the engine off.
2. Press the TRIP button so the OIL LIFE percentage is displayed.
3. Press RESET and hold for two seconds. OIL LIFE REMAIN 100% will appear.
