Report A Problem

Illumination of the Check Engine Light can be caused by a loose or worn gas cap.

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 water pump may develop a coolant leak resulting in an engine overheating condition.

 

The serpentine belt tensioner pulley may wear out. Our technicians tell us that in order to get a new pulley from General Motors you must purchase a complete belt tensioner assembly.

 

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.

The fuel pump may fail causing engine to stall and not restart.

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.

The oxygen sensor can fail causing Check Engine Light illumination and the engine to run rich (burn more fuel than normal).

The steering may develop a clunk type noise from the upper intermediate steering shaft.  Our technicians tell us that you should check with your local GM dealer to find out what the latest repair is for this condition.

The high pressure power steering hose will commonly leak fluid; it should be replaced.

AC/heat works fine for the driver side. Passenger side produces heat only and does not respond to any attempts to change temperature.
