How do I replace the thermostat in a 2013 Chevrolet Malibu?

★ Top Answer

If you suspect that the thermostat in your 2013 Chevy Malibu is not functioning properly, the best course of action is to replace it entirely. Typically, an indication that your thermostat is faulty is when the car's heater is ineffective at warming up the vehicle. This often signals that the thermostat is stuck closed, preventing hot coolant from reaching the heater core. To replace the thermostat, begin by locating the upper radiator hose and tracing it to the housing. Then, carefully remove the thermostat housing cover, followed by unscrewing the thermostat from its secure position with two bolts. Reversing these steps, install the new thermostat in place.
