1990 Chevrolet G Series Van (G30) 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.

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.

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

1990 Chevrolet G Series Van (G30) Reviews

An excellent vehicle with some previous owner issues - such as no oil changes, lights not replaced or repaired, fuel inlet restrictor damaged/missing, missing sound system but intact radio/cassette player, and otherwise shoddy repairs to the whole of the vehicle. But, as with any gem in the rough, this vehicle has a great engine and transmission with low (for the year) miles.
