Check the radiator fins for obstruction by insects or mud. Clean off any obstructions with a stream of low-pressure water.
| WARNING The cooling fan spins at high speed and can cause serious injuries. Keep your hands and clothing away from the cooling fan blades at all times. |
NOTICE
Using high-pressure water, as from a car wash facility, could damage the radiator fins and impair the radiator’s effectiveness.
Do not obstruct or deflect airflow through the radiator by installing unauthorized accessories in front of the radiator or behind the cooling fan. Interference with the radiator airflow can lead to overheating and consequent engine damage.
