1990 GMC S15 Jimmy 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.
A coolant leak may develop from the water pump. This can result in an engine overheating condition. A leaking water pump will require replacement.
The alternator may fail, causing a "no charge" condition. An internal bearing may also fail and cause an abnormal noise. If the vehicle is driven too long with a failed bearing, the alternator may stop turning, which can cause the serpentine belt to break or the engine to stall and not turn over.
Our technicians highly recommend that the transmission is serviced every 30,000 miles to avoid problems and maintain optimal operating order.
