The head light switch may fail causing erratic head light operation.
A failing crankshaft position sensor may cause the engine to stall intermittently.
The radiator may leak from the plastic side tank area. The coolant loss could cause the engine to overheat. Our technicians warn that overheating these engines can lead to head gasket failure.
The transmission pressure control solenoid may fail causing erratic shifting. Our technicians tell us that partial dis-assembly of the transmission is necessary to replace a failed pressure control solenoid.
An automatic transmission fluid leak may develop from the rubber section of a transmission cooler line. In some cases the rubber section of hose can be replaced. In others, the complete cooler line must be replaced to correct this type of leak.
It is common for the sending unit to read the fuel level incorrectly. This is due to a defective module. Our technicians recommend having the complete fuel pump and sending unit replaced because the module is currently not offered separately from the pump and sending unit.
Overheating of the engine may cause the cylinder head to expand, severely straining the head bolts and damaging the threads in the engine block. This commonly results in a blown head gasket . Our technicians tell us the engine block threads must be repaired before the cylinder head is reinstalled.
Water may be drawn into the secondary air injection (AIR) pump causing the pump to fail and the Check Engine Light to illuminate. Our technicians tell us there is a kit available from General Motors to relocate the air intake for the pump which should prevent future damage from water intrusion.
The fuel pump may fail causing the engine to stall and not restart.
A loose or worn gas cap may cause check engine light to illuminate.
The intermediate steering shaft may cause a clunking noise when turning and require replacement.
The front struts may show signs of wear, or be excessively bouncy ride at freeway speeds. This may begin to occur at around 75,000 miles.
Brake fluid can become dirty and may cause problems in the brake system ; it should be flushed every 60,000 miles.
Our technicians recommend to replace the fuel system filter every 30,000 miles.
You may be able to prevent transmission problems by servicing the transmission and inspecting the fluid every 30,000 miles. If the fluid is dark or burned then the transmission system should be completely flushed .
Extended life coolant may become contaminated and require cooling system service before the recommended 100,000 miles.
The spark plugs should be replaced every 100,000 miles. Our technicians recommend replacing the spark plug wires also at this time.
