GMC Vandura 3500 Problems

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.

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.

GMC Vandura 3500 Questions

i have no heat. I replaced the heater control valve in front of the heater core outlets (wich I flushed) she comes up to operating temp just fine. Should have good heat but nothing. Is it possibly something in the heater controls?? All my doors work when I use the controls and the heater valve ...

When I start my truck in the morning it will not shift out of low gear. when it gets to 170 degrees I can shut the truck off and turn it back on and it will shift normally. But if I do not shut the truck off it will not come out of low gear.
