A coolant leak may develop from the water pump. This can result in an engine overheating condition. A leaking water pump will require replacement.
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.
