Radiator and Cooling Fan

Check and clean the screen and radiator fins for obstructions caused by
insects or mud. Refer to the Periodic Maintenance Schedule beginning
on page 54.
Washing the vehicle with a high-pressure hose could damage the
radiator fins and impair the radiator's effectiveness. Exercise
caution if a high-pressure system is used for washing the vehicle.
Do not obstruct or deflect air flow through the radiator by installing
unauthorized accessories in front of the radiator or behind the cooling
fan. Interference with the radiator air flow can lead to overheating and
consequent engine damage.
Coolant absorbs excessive heat from the engine and transfers it to the
air at the radiator. If the coolant level becomes low, the engine
overheats and may suffer damage. Check the coolant level each day
before operating the vehicle, and replenish coolant if the level is low.
Change the coolant as outlined in the Periodic Maintenance Schedule.
