Filling and bleeding cooling system: Before filling, turn the ignition ON (do not start engine). Set the temperature controls in the vehicle interior to full warm and the blower fan speed to Low. Using a 50% distilled water 50% engine coolant mix, slowly fill the expansion tank until the coolant level indicator reaches MAX. The level indicator diagram is located on the tank (green arrows). Reference this when filling to obtain the correct level. Trapped air is common when filling a cooling system and can result in improper cooling. It is important to bleed your cooling system each time the cooling system is serviced. Install the expansion tank cap and be sure all bleeder screws are tight. Start and run the engine at idle until it reaches operating temperature and check the cooling level. Top it up with coolant as needed. When done, check the cooling system for leaks.
