Some 2011-12 Chevy Cruze models with 1.4-liter turbocharged engines may produce a coolant leak, a hot engine message on the dash and/or insufficient heater output.
One probable cause for all these troubles is loose water pump bolts. Unfortunately, you can't just snug down the bolts and send the customer on his way because the leak will resurface, according to GM.
Replacing the water pump, pump gasket, pump retaining bolts, thermostat and engine mount bracket bolts is the correct fix. Here are the part numbers you'll need to complete the swap:
- Water Pump (Part No. 55579016);
- Pump Gasket (Part No. 55568033);
- Thermostat (Part No. 55579010); and
- Pump Retaining Bolts (3) (Part No. 11588757)
