Cooling solution exceeding 50% antifreeze can result in engine overheating and damage to the engine. Coolant solution must be premixed before adding to radiator.
Periodically remove the dirt from the radiator fins.
Periodically check the fan belt and radiator hoses.
Replace if signs of deterioration are found.
TIGHTENING THE FAN BELT
If the fan belt is loose, the engine can overheat and the battery lose its charge. Check tightness by pressing on the belt midway between the pulleys. It should deflect about 0.28 to 0.35 in. under a load of 22 lbs. (7 to 9 mm/10Kg).
