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.
Our technicians recommend flushing the brake fluid every 60,000 miles. Brake fluid that is dirty may cause problems in the brake system.

An engine vacuum leak may develop from the throttle body gasket causing a higher than normal idle speed. Failed gaskets should be replaced.

1993 Chevrolet G Series Van (G20) Reviews
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.
