Summary

31170 01 - Service Update. Certain vehicles may have contact between the rear leaf spring shackle bolt and rear HVAC coolant lines that may rub through creating a coolant leak. This leak may cause the engine to overheat, leading to loss of propulsion or loss of HVAC performance. Dealers will replace the shackle bolt; inspect and, if necessary, replace the auxiliary heater hose.
