CHECK ENGINE COOLANT LEVEL

The engine coolant level and quality should be checked before each use, when the engine is cool and off.

The cooling system is a closed type. Never open the radiator cap. Doing so may induce air into the cooling system and may cause overheating.

1.Check the coolant level only at the overflow reservoir (A, Figure 18). The coolant level should be between the “H” and “L” marks.

2.If the coolant level is insufficient, remove the cap

(B) from the reservoir and add coolant to the “H” mark.

3.Reinstall the cap.

NOTE: Proper coolant mix is a 50/50 mixture of ethylene glycol and distilled water. See engine owners manual for engine coolant specifications.

CHANGE ENGINE COOLANT

See engine owners manual for specific engine coolant change procedures.

CLEAN RADIATOR & SCREEN

Clean the radiator and screen before each use, or as required (depending on conditions) to allow proper air-flow through the radiator.

1.To remove the radiator screen, lift the seat.

2.Release radiator screen latch (C), slide towards the left hand side of the machine. Lift screen enough to clear radiator cap and slide out the front.

3.Flush the screen with water or blow clean with air. Flush the radiator core with water or blow clean with air. See engine owners manual for proper radiator cleaning procedures.

4.To reinstall the radiator screen, reverse removal process.

WARNING

PRESSURIZED SYSTEM

Hot coolant can cause serious burns. Never open the radiator cap. Wait until the engine is cool before checking the coolant level or removing the reservoir cap.
