Fits 2011 Cruze LT 1.4L (but sticks open after 5 weeks post install)
Reviewed in the United States on January 18, 2020
My engine is not getting up to temperature. I thought the installed thermostat had broken its retainer tabs and was stuck open. As it turned out the ADC thermostat that had been installed for 18 months had not broken. I installed the New Yall thermostat and replaced the used coolant with new Dexcool. The engine still does not get up to temperature but does not appear to be leaking coolant. Will have to use electric space heater for morning defrosting. Will update when problem solved and when New Yall thermostat plastic tabs break. It is helpful to place a towel under the thermostat when installing bolts so as to catch them in case of dropping. Torque screws to 71 inch-pounds and ensure water pump mating surface is clean. Included gasket/seal seems to be same as ACD.
Edit 1-20-20: Used E10 socket for thermostat bolts. Replaced drained coolant with fresh Dexcool. Initially New Yall thermostat seemed to be staying open; engine was not heating up to 217°F. I tied a piece cardboard to the front grill to block air from the radiator. After a short drive, engine temperature rose to 221°F while running with AC on full for 5 minutes. Temp stabilized at 221°F as ECM applied voltage to thermostat's heater to force it full open. Then parked and removed cardboard then turned on heat with fan on position 4 with hood up to let it cool down. On next test drive engine heated up normally and held 217°-219° on freeway. Will update again when thermostat fails next time.
Edit: 4-3-20 It sticks open so engine does not get up to temperature. Worked okay for 5 weeks then failed. Will install ACD part next time.
