CHANGING COOLANT
WARNING
Never remove radiator cap or radiator
reservoir cap while the engine is hot or
running. Severe thermal burns or inju
ry can occur by escaping steam or hot
engine coolant.

Stop engine and allow to cool before removing
radiator or reservoir cap.
•
To remove reservoir cap after engine is cool, place a
thick cloth over cap and remove it slowly.
•
To remove radiator cap after engine is cool, place a
thick cloth over cap and rotate it slowly counter clock
wise to the first stop. Pressurized steam may emit
from the cap, stand back to avoid injury. Once all
pressure is released, rotate cap counter clockwise
while pushing down on cap to remove.
CAUTION: Used coolant is a hazardous waste product.
Dispose of used coolant properly. Check with your local
authorities, service center, or dealer for safe disposal/re
cycling facilities.
Coolant temperature gauge (if

equipped) should read be
tween 175_ and 195_ F (80_
and 90_ C) when engine is
running.
If coolant temperature rises above 220_ F (105_ C), the
temperature light (if equipped) will illuminate. Idle engine
down for a while. Then stop engine. Once engine is cool
ed, check coolant level, fan belt tension and clean any
clogged radiator fins.
Coolant should be replaced every year, unless an ap
proved extended life coolant is used. Then replace every
3000 hours.
• A 50/50 mixture of phosphate free antifreeze and tap
water is required for heat dissipation, rust resistance
and lubrication.

gasoline (gasoline blended with an alcohol or an ether),
run engine until it stops from lack of fuel, or b) if fuel tank
contains gasoline, either run engine until it stops from lack
of fuel, or add a gasoline additive to the gas in the tank.
(See parts list. Single use pouches of gas additive are
available from your service dealer.) If you use a gas
