Maintenance Recommendations

^ At least once per year, the front face of the radiator should be cleaned. In northern climates, spring is a good time of year to do this cleaning, as road salt residue on the radiator can cause corrosion.
^ Insects, leaves and other debris can be removed by blowing compressed air through the radiator core from the back. Water can be used on both sides of the radiator.

WARNING: To avoid the danger of being burned, do not remove the coolant reservoir cap when the coolant is boiling, and do not remove the radiator cap when the engine and radiator are still hot. Scalding coolant and steam can be blown out under pressure if radiator cap or reservoir cap is taken off when system is hot.

CAUTION:
^ Never spray cold water on a hot radiator.
^ The radiator fins are necessary for good heat transfer and should not be brushed to prevent damage to the fins.
