16. Once the installation of your new Mustang Stock Replacement Radiator is complete, you must fill your new radiator with a 50/50 antifreeze mix. Fill the radiator and overflow tank to the top, reconnect the negative battery terminal, then run the engine with the heat on until the engine warms up to allow the coolant to circulate and allow you to check for leaks. After a few minutes of running the engine and using the heat, you can shut off the engine and top off the antifreeze again.
