The owner of a 2011-12 Chevy Cruze with a 1.4L turbocharged engine may come into your store with a complaint of 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. If you think you can just snug down the bolts and send the customer on his way, think again; the leak will resurface GM warned.
Replacing the water pump (Part No. 55579016), pump gasket (Part No. 55568033), pump retaining bolts (Part No. 11588757), thermostat (Part No. 55579010) and engine mount bracket bolts (Part No. 11570514) is the correct fix.
