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.

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.
