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. Power SteeringFluid Thermostat 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. The power steering fluid reservoir is located to the right of the engine coolant reservoir, at the back of the engine compartment. 6-22
