When squeezing the radiator hoses:
Wear protec tive gloves . Be c areful as the radiator hos es are hot. Keep your hands away from the c ooling fans . NOTICE: M ake s ure that the radiator res ervoir s till has s ome c oolant in it. I f the c oolant temperature gauge indic ates an exc es s ive temperature, turn off the engine and let it c ool. I f there is not enough c oolant, the engine may overheat or be s erious ly damaged. I f the radiator res ervoir does not have enough c oolant, perform the following: 1 ) s top the engine, 2 ) wait until the c oolant has c ooled down, and 3 ) add c oolant until the res ervoir is filled to the full line.
