To Add Coolant If you need more coolant, add the proper mix at the cnolclnt recoverv tank. Radiator Pressure Cap NOTICE: Your radiator cap is a psi (105 kPa) 15 pressure-type cap and must be tightly installed to prevent coolant loss and possible engine damage from overheating. Be sure the arrows on 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. Thermostat Add coolant mix at the recovery tank, but be careful not to spill it. Engine coolant temperature is controlled by a thermostat in the engine coolant system. The thermostat stops the flow of coolant through the radiator until the coolant reaches a preset temperature. When you replace your thermostat, an AC@thermostat is recommended. 6-24
