Check out the how to section http://www.cruzetalk.com/forum/129-...place-thermostat-housing-thermostat-1-8l.html. This is for the 1.8 but it may be able to give some assistance as to what needs to be done. Course you never mentioned which engine you had so..... Check it out.So i checked the fluid levels in the car. It does not look to be losing any fluid and the fluid level is not low. Looks like the thermostat is shot, has anyone changed the thermostat in their Cruze?
