MAINTENANCE
If the engine has been running, the pressurized, hot
coolant can escape and cause severe burns.
• Do not remove the radiator cap when the
engine is hot. Always allow the engine to cool
at least 15 minutes or until the radiator cap
is cool enough to touch without burning your
hand before removing the radiator cap.
• Do not touch radiator and surrounding parts
that are hot.
• Use a rag when opening the radiator cap, and
open the cap slowly to allow steam to escape.

Cleaning Radiator

The engine fan draws the air from the engine compart-
ment and pushes the air through that hydraulic oil cooler
and radiator. Remove any build up of debris on the oil
cooler and radiator with compressed air.

Engine Coolant

If you need to add engine coolant, refer to "Checking,
Adding & Bleeding the Engine Coolant" on page 4-138.
Change the engine coolant yearly. Refer to "Changing
Engine Coolant" on page 3-10.
