Checking the Radiator Coolant

Note: Do not open the radiator cap. Doing this may
introduce air into the cooling system.
1. Position the machine on a level surface, stop the
engine, and set the parking brake.
2. Raise the seat.
3. With the engine cool, check the overfl ow bottle level.
The fl uid needs to be up to the indicator line (bump)
on the outside of the overfl ow bottle (Fig. 646).
4. If the coolant level is low, add a 50/50 mix of extend-
ed life antifreeze/Dex-Cool® and water to the over-
fl ow bottle. Fill the overfl ow bottle to the indicator line
on the bottle (Fig. 646).
