Locate the thermostat. The thermostat is typically located in the upper radiator hose.
Disconnect the negative battery terminal. This will prevent any electrical shorts from occurring.
Remove the old thermostat. Use the wrench to loosen the bolts that hold the thermostat in place. Be careful not to drop the old thermostat into the engine.
Install the new thermostat. Make sure that the new thermostat is facing the correct way. The gasket should be facing the engine.

Reconnect the negative battery terminal.
Start the engine and let it run for a few minutes. Check for any leaks.
