Chevrolet G Series Van (G20) Repair and Maintenance

A guide to problems, costs, maintenance and repair for your Chevrolet G Series Van (G20)

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.

Very Pleased with vehicle. Had to replace Transmission due to prior owner abuse. Need to change fuel pump, don't know where relay is for fuelpump. Any help would be great. Also is a bit hard on fuel. Any tricks beyond standard tuneup would be great. Can't invest too much $$$ due to being disabled.
