~~ILOWCOOLANTLEVELAdding CoolantIf this light comes on, itmeans you’re low onengine coolant.If you need more coolant, add the proper DEX-COOL@coolant mixture at the coolant recovery tank, but becareful not to spill it.Turning the radiator pressure cap when theengine and radiator are hot can allow steam andscalding liquids to blow out and burn you badly.With the coolant recovery tank, you will almostnever have to add coolant at the radiator.Never turn the radiator pressure cap -- even alittle -- when the engine and radiator are hot.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.Radiator Pressure CapI NOTICE:Your radiator 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, a GM capis recommended.6-23
