Make sure the car engine is completely cool before beginning the replacement process. There is a substantial risk to burn yourself if the engine has not had ample time to cool. Allow at least a 2 hour gap between the last time the car was running and the beginning of the work.

The radiator and cooling system must be properly drained before this procedure. That process will not be shown in this guide.

Disconnect the negative cable from the car battery to eliminate the risk of being shocked while working. Allow car to sit for 5 minutes to make sure leftover power is discharged completely.
