1994 Chevrolet Caprice Problems
RepairPal has identified the most common problems with the 1994 Chevrolet Caprice based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
The auto level ride compressor may fail causing the rear of the vehicle to ride to high or too low.
A coolant leak may develop from the water pump. The engine may overheat as a result of the coolant loss. A leaking water pump should be replaced.
The intake manifold gasket may develop and external engine oil or coolant leak. In some cases, an internal coolant leak may occur causing coolant to mix with the engine oil. Our technicians tell us that operating the engine with a coolant/oil mix can result in internal engine damage. Replacing the intake manifold gasket should correct these leaks.
The spark plugs should be replaced every 30,000 miles and the spark plug boots should be checked for hot spots and cracks.
Vehicles using the enhanced vortec V6 engine may be hard to start run poorly and/or use to much fuel due to a fuel leak inside the intake manifold plenum. Commonly this is caused by a leaking fuel pressure regulator or fuel line. The fuel system will need to be pressurized with the upper intake manifold removed in order to determine the exact cause of the leak. Removing the "tuning valve" from the upper intake can allow for limited visual inspection without removing the upper intake manifold.
A burning smell may develop due to an oil leak form one or both valve cover gaskets. Resealing the valve cover will generally correct this concern. However, the valve covers should be inspected and replaced if damaged.
The idler arm or pitman arm may wear causing looseness in the steering. When this occurs the front suspension will not be able to be aligned correctly.
