To avoid being scalded, neverchange thecoolant whenthe
engine ishot.

-DRAINING ENGINECOOLANT-
1. Turn ignition switch"ON".Moveheater "TEMP" control
knob allthe way to"HOT".
2. Open radiator drainplugatthe bottom ofradiator, and
remove radiator cap.
3. Remove reservoir tank,drain coolant, thenclean reservoir
