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. Our technicians tell us that operating the engine with a coolant/oil mix can result in internal engine damage. Replacing the intake manifold gasket should correct these leaks.
The high pressure power steering hose will commonly leak fluid; it should be replaced.
The mass air flow or crankshaft position sensor may fail causing the engine to intermittently stall. It may be necessary for the engine to cool down before it will restart.
One or more of the power windows may stop working due to a failed window switch. Failed switches will require replacement.
The spark plugs should be replaced every 30,000 miles and the spark plug boots should be checked for hot spots and cracks.
One or more power windows may stop working due to a failed window motor or switch. Proper diagnoses will be necessary to determine the exact cause.
An engine oil leak may develop from the rear of the engine. This is commonly caused by a failed oil pump drive o-ring seal. The leaking o-ring should be replaced to correct this concern.
