Chevrolet G Series Van (G20) Problems
Intake Manifold Gasket May Leak Coolant or Engine Oil
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.
Coolant Leak & Engine Overheating
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 or Crank Over But Not Start
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.
Highter Than Nornal Idle Due to Vacuum Leak
An engine vacuum leak may develop from the throttle body gasket causing a higher than normal idle speed. Failed gaskets should be replaced.
Oil Leak From Distributor Shaft Seal
An oil leak may develop from the distributor o-ring seal requiring replacement of the seal.

Chevrolet G Series Van (G20) Stories
I have had the same 1995 Chevy van since we bought it new off the lot, and it has 206K miles on it. We've put on every single one, and this is my favorite vehicle. A lot of the bells and whistles have broken, but the engine and transmission have never failed me. I've had to replace the steering box and front end suspension due to a wreck, but the only thing I've ever had to replace due to wear and tear is the fly wheel and radiator. I love my van and will drive until it won't drive anymore.
Many yes, many not perfect but I love it...
Body style is old school but who cares, this van is a wonderful machine. No complaints.
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.
when wet outside brakes are very grabby hydroplanes
