NOTE: Before filling, switch on ignition, set heater control to maximum temperature and set fan to low speed. This opens heating valves and installed auxiliary water pump runs if necessary.

Perform filling operation slowly.

Fill expansion tank completely and wait until coolant emerges at vent point(s) without bubbles. Close bleed screw(s).

NOTE: Only use specified coolant.
