- Summary
- 13079 - Customer Satisfaction Program. Vehicles may have leaks from the water pump shaft seal. These leaks are often due to vehicle operation with a low engine coolant level. Proper maintenance of the engine coolant level will increase shaft seal reliability and help ensure that the water pump operates as intended. Dealers are to check the engine coolant level and, if necessary, add the proper mixture of coolant directly to the radiator and the coolant recovery tank.
Owners of these vehicles have filed 1,112 complaints in the engine category.
