1982 Corvette Restoration

Article by Mark Trotta

As the all-American sports car, Corvettes are in a category all their own. There is no other production car that comes close to it in terms of enthusiast interest, loyal following, collectability, and iconic status.

1980-1982 Corvettes

With the advent of emissions controls and safety regulations, the diminished horsepower of 1980-1982 Corvettes are often lamented by classic car snobs. What these people fail to realize is that early eighties Vettes, developed and refined for over a decade, are the smoothest and most reliable of all C3 models.

In 1980, Corvette engineers found ways to lose nearly 250 pounds from previous models. This included a switch from cast-iron to aluminum on intake manifolds and differential housings. At 3,495 pounds, it was the lightest Vette since the first C3, the 1968 model.

A redesigned front-end included an integral air dam and three-piece spoiler. Not only did the new nose improve airflow to the radiator, it also lowered the car's drag coefficient from 0.50 to 0.44. A redesigned back panel featured a built-in spoiler.

The U.S. Oil Crisis of the seventies and ever-increasing emissions laws made fuel efficiency a priority. 1981 marked the beginning of computer-run engines, which provided better fuel metering and driveability.

Further weight reduction on the Corvette included replacing the steel rear transverse spring with one made from reinforced plastic. Manual-shift models kept the multi-leaf steel spring, as did those with the optional Gymkhana suspension. New stainless-steel free-flowing exhaust manifolds weighed 14 pounds less than the previous year's cast-iron manifolds.

Air conditioning and power windows were standard equipment on all 1980-1982 models (optional on earlier models). So was tilt/telescope steering wheel, a nice feature to have, considering how "cozy" C3 Corvette interiors are to begin with.

In June of 1981, Corvette production transferred from St. Louis, Missouri to Bowling Green, Kentucky. The new state-of-the-art facility, covering 212 acres, was a giant step in reversing the car's reputation for sub-standard quality finish. Lacquer paint was phased out; Corvettes were now finished in durable two-stage enamel.

All 1982 Corvettes were equipped with the L83 Crossfire fuel-injected engine. A low-pressure high-volume electric fuel pump was mounted inside the gas tank, replacing the mechanical-style pump used on all previous Vettes.

The L83 Crossfire engine used in 1982 and 1984 Corvettes was designed well enough that there is no need to tamper with it. Using a good grade of premium gas and changing the fuel filter regularly is all that is required. However, if you're having problems, here are some basic diagnostic procedures. A shop manual is invaluable.

With the all-new C4 Corvette due out the following year, combined with an on-going dispute with Borg-Warners, Chevrolet did not to offer any drive train options in 1982. GM's new 700R automatic transmission was installed in all models. The four-speed overdrive unit helped achieve the quickest acceleration times since the 1974 Corvette, and at the same time return its best fuel-mileage yet.

Underneath, the brakes, steering, and suspension parts are readily available, but those fiberglass panels can be tough to get right once hit. There's a great aftermarket for all classic Corvettes, and third-generation cars are no different.

The 1982 Corvette seen in these pictures has been in the family since 1993. It had previously been hit in the front. I repaired the right fender and replaced the right-side headlight bucket. The front bumper on the car is an aftermarket upgrade, Ecklers part #10339. It is made of fiberglass instead of the original soft urethane, and holds its shape better.

The catalytic converter was missing when I got the car, and there was nothing but a single straight pipe running to the back of the car. No mufflers, either. Not only did the car sound awful, it never would have passed state inspection. (U.S. Federal law makes it illegal to remove or disable any automotive emission equipment on a street-driven vehicle.) I replaced the exhaust system from the exhaust manifolds back.

1982 was the last year Corvette motors had accessory V-belts (there were four of them). The next generation would have a serpentine drive-belt. Changing the valve cover gaskets on 1980-1982 Corvettes is time consuming. Lots of stuff has to be removed to get to them and there's not a lot of room to work in.

After an August morning cruise in 2009, I stopped by a friend's house for a visit. Upon leaving, I got in the Corvette, put the key in the ignition, and turned it forward. Nothing. I turned the key back and tried it again. Nothing, not even the usual resistance that should spring the key back. My first thought was the key cylinder had broken. After all, the car was 30 years old. Little did I know I was in for a crash course in Corvette steering column repair.

Power steering was an option on Corvettes from 1963 to 1976, and standard on 1977-1982 models. The power steering system on all C2 and C3 Corvettes consists of a pump, a control valve, and a power cylinder. These components are connected to each other by four hydraulic hoses.

Around 2011, I noticed a power steering fluid leak under the Corvette. I was pretty sure the steering system was all original, so I decided to rebuild/replace the entire system. After rebuilding the control valve and steering cylinder, I replaced the four P/S hoses. Procedures for 1963-1982 Corvettes are virtually the same.
