2006 Chevrolet Malibu Change the Thermostat
The thermostat in the 2006 Chevrolet Malibu regulates the engine temperature by allowing or restricting the flow of fluid that goes through the coolant veins inside the engine block and engine heads. At 180 degrees F, the thermostat opens and forces more fluid though the engine. This lowers the temperature in the engine to prevent overheating. At some point, the thermostat will fail. When this happens, the engine could overheat and cause thousands of dollars in damages.
 Tools Used
 Change the Thermostat
- Remove the two bolts that secure the T-Stat housing to the right engine head. To locate the housing, follow the upper radiator hose to the engine head. The hose connects to the T-Stat housing.
- Lift the T-Stat housing upward and remove the thermostat from the engine head.
- Clean the old gasket off the engine head. Use a small scraper or wire brush if necessary.
- Place the spring end of the thermostat into the engine head and then place the thermostat gasket over the thermostat.
