DEFECT INVOLVED
General Motors has determined that some 1992-93 Pontiac Sunbird model vehicles equipped with a 2.0L engine may have been assembled with the incorrect coolant pump. Coolant may leak past the internal coolant pump seal and into the pump bearings. This may cause premature bearing failure resulting in a coolant pump knocking noise. If not repaired, this condition may result in a loose timing belt tensioner which could cause the engine to fail to start.
To prevent this condition from occurring, dealers will inspect your vehicle's coolant pump and, if necessary, replace the coolant pump.
VEHICLES INVOLVED
Involved are certain 1992-93 Pontiac Sunbird model vehicles equipped with the 2.0L engine that fall within the VIN breakpoints as shown.
Vehicles which Pontiac records indicate were previously repaired under warranty with coolant pump P/N 93221331 or P/N 93215645 are not included in this campaign.
All vehicles listed on the dealer printout will require inspection, and as necessary, correction. Other suspect vehicles should be checked for campaign involvement by utilizing the Vehicle Information Service System (VISS) for verification.
