1994 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.

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.

1994 Chevrolet G Series Van (G20) Questions

Been having some issues with rear end noise when shifting from P to D and while driving from 1st to 2nd gear. The u joints are good but there is play in the driveline. Has 150,some odd miles. Should I replace the whole rear or just the gears and bushings?

When I turn in the switch the pump runs for about 10 seconds. I was told that the pump should run for 2 seconds.

If the 2 seconds is correct, should I worry about running 10 seconds.

What will cause this.
