To Check Coolant When your engine is cold, thecoolant level should be at "FULL COLD" or a little higher. When your engine is warm, the level should be up to "FULL HOT" or a little higher. To Add Coolant If you need more coolant, add the proper mix at the coolant recovery tank. Radiator Pressure Cap NOTICE: Your radiator capis a15 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. Add coolant mix at the recovery tank, but be careful not to spill it. When you replace your radiator pressure cap, an AC@ cap is recommended. 230
