Engine Coolant System

It is important that the cooling system of the engine be maintained properly to ensure proper performance and longevity.

WARNING Hot pressurized coolant can cause severe injury.

•DO NOT open radiator cap when hot.

•Before servicing, allow coolant to cool.

NOTICE Alcohol or methanol based anti-freeze or plain water are not recommended for use in the cooling system at any time.

The cooling system must be maintained according to the recommended maintenance schedule and inspection should include:

•The regular removal of dust, dirt, debris from the radiator core and fan shroud.

•Inspection of coolant hoses and components for leaks, especially at the radiator hose connections. Tighten hose clamps if necessary.

•Check radiator hoses for swelling, separation, hardening, cracks, or any type of deterioration.

•Inspect the radiator cap to ensure proper sealing.
