1992 Chevrolet G Series Van (G20) Problems

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. Running the engine with a coolant/oil mix may result in engine damage. Replacing the intake manifold gasket should correct this issue.

A coolant leak may develop from the water pump. This can result in an engine overheating condition. A leaking water pump will require replacement.

The fuel pump may fail causing the engine to stall and not restart. Our technicians recommend replacing the fuel filter every 30,000 miles to help prevent undue strain on the fuel pump.

If I can get it rolling then it runs great and when not hot weather it runs great. There is a switch for turning off lights while doors are open but doesn't seem to work, so interior lights stay on when d...

I was driving my 1978 GMC 3/4 ton van from Connecticut to Maryland for the Thanksgiving weekend, 1985. 10PM at night,65MPH, extremely light traffic.
