Any trace amounts of oil or grease in the coolant dramatically reduces heat transfer. Odds are however with the age and hours. The fan/waterpump pulley and generator pulleys are worn from dust and a loose belt. Just eyeballing the pulleys won't indicate wear either. Over tightening the belt may reduce slippage BUT the generator gearing and water pump bearings will soon require replacement.   [Reply]  [No Email]
