Radiator and Cooling Fan
Always check and clean the radiator and fans at the intervals outlined in the Periodic Maintenance Chart beginning on Periodic Maintenance.
NOTICE
Washing the vehicle with a high-pressure hose
could damage the radiator fins and impair the radiator's effectiveness.
Using a high-pressure system is not recommended.
CAUTION
Inspecting the cooling fans
while the engine is running or when the engine is still hot can result
in injury. Always make sure the engine is both off and sufficiently
cooled before inspection.
-
Check radiator air passages for restrictions or damage.
-
Carefully straighten any bent radiator fins.
-
Inspect the cooling fans for smooth rotation.
-
Remove any obstructions with low pressure compressed air or low pressure water.
