With the coolant recovery tank, you will almost never have to add coolant at the radiator. Never turn the radiator pressure cap even a little when the engine and radiator arehot. -- -- Adding Coolant If you need more coolant, add the proper mix at the coolant recovery tank. Add coolant mix at the recovery tank, but be careful not to spill it. You can be burned if you spill coolant on hot engine parts.
