Turn ignition switch ON and set temperature control lever all the way to HOT position or the highest temperature position. Wait 10 seconds and turn ignition switch OFF.

CAUTION: Do not to allow the coolant to contaminate the drive belts.

When draining all of the coolant in the system for engine removal or repair, it is necessary to drain the cylinder block. Remove the cylinder block drain plugs, and block heater if equipped, to drain the cylinder block as shown.
NOTE: For Canada, the "D" cylinder block drain plug as shown, is not a cylinder block drain plug but a block heater.
