Liquid Cooling System
Checking/Filling
1. Remove the rubber access plug from the front fender.
XR061
2. Carefully rotate the radiator cap counterclockwise to
release pressure; then remove the cap.
XR060
3. Add coolant as necessary; then install the radiator
cap and access plug.

NOTE: Use a good quality, biodegradable gly-
col-based, automotive-type antifreeze. When filling
the cooling system, use a coolant/water mixture which
will satisfy the coldest anticipated weather conditions
of the area in accordance with the coolant manufac-
turer’s recommendations.
While the cooling system is being filled, air pockets may
develop; therefore, run the engine for five minutes after
the initial fill, shut the engine off, and then fill the cool-
ing system to the bottom of the stand pipe in the radiator
neck.
