WARNING:
To help avoid danger of being burned, do not remove radia-
tor cap while engine and radiator are still hot. Scalding fluid
and steam can be blown out under pressure if cap is taken
off too soon.
CAUTION:
The cap of thermostat cap must not be removed.
1) Remove radiator cap when engine is cool.
2) Loosen radiator drain plug (2) to drain coolant.
3) Remove reservoir, which is on the side of radiator, and drain.
4) Tighten plug securely. Also reinstall reservoir.
5) Fill radiator with specified amount of coolant, bleed air from cool-
ing system by disconnecting heater breather hose (3) and loos-
ening thermostat cap breeder bolt (1).
6) Fill reservoir with coolant, install radiator cap and run engine for
2 or 3 minutes at idle. This drives out any air which may still be
trapped within cooling system.
7) STOP ENGINE. Add coolant as necessary until coolant level
reaches filler throat of radiator when engine cold. Reinstall ra-
diator cap.
