Add coolant mixture at the recovery tank, but be careful not to spill it. Radiator Pressure Cap The radiator pressure cap is located in the engine compartment on the passenger's side of the vehicle. CAUTION: You can be burned if you spill coolant on hot engine parts. Coolant contains ethylene glycol, and it will burn if the engine parts are hot enough. Don't spill coolant on a hot engine. Occasionally check the coolant level in the radiator. For information on how to add coolant to the radiator, see "Cooling System" in the Index. NOTICE: Your radiator cap is a 15 psi (105 kPa) 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. 6-32
