Cooling System
RADIATOR CAP
1. Make sure the engine and
radiator are cool.
2. Turn the radiator cap counter-
clockwise, without pressing down
on it, until it stops. This relieves
any pressure remaining in the
cooling system.
Maintenance
3. Remove the radiator cap by
pushing down and turning
counterclockwise.

the base of the filler neck. Add
coolant if it is low.
5. Put the radiator cap back on.
Tighten it fully.
RESERVE TANK
6. Pour coolant into the reserve tank.
Fill it to halfway between the MAX
and M I N marks. Put the cap back
on the reserve tank.
