Radiator Pressure Capnrning the radiator pressure cap when the engineand radiator are hot can allow steam and scaldingliquids to blow out and burn you badly. With thecoolant recovery tank, you will almost never haveto add coolant at the radiator. Never turn theradiator pressure cap -- even a little -- when theengine and radiator are hot.Add coolant mix at the recovery tank, but be careful notto spill it.You can be burned if you spill coolant on hotengine parts. Coolant contains ethylene glycol,and it will burn if the engine parts are hotenough. Don’t spill coolant on a hot engine.NOTICE:Your radiator pressure cap is a 15 psi (105 kPa)pressure-type cap and must be tightly installed toprevent coolant loss and possible engine damagefrom overheating. Be sure the arrows on the capline up with the overflow tube on the radiatorfiller neck.When you replace your radiator pressure cap, an AC@cap is recommended.ThermostatEngine coolant temperature is controlled by a thermostatin the engine coolant system. The thermostat stops theflow of coolant through the radiator until the coolantreaches a preset temperature.When you replace your thermostat, an AC@ thermostatis recommended.
