Be sure the arrows the cap line up with the overflow tube on the radiator filler neck. When you replace your radiator pressure cap, an AC@ cap is recommended. -- -- Add coolant mix at the recovery tank, but be careful not to spill it. Thermostat You can be burnedif you spill coolant on hot engine parts. Coolant contains ethylene glycol, and itwill burn if the engine parts are hot enough.
