Maintenance and Specifications 8. Add coolant/water mixture through the thermostat housing opening until full at housing opening. 9. Install the thermostat housing bleed plug. Install metal pin by pushing into the slot. After any coolant has been added, check the coolant concentration, refer to the Checking engine coolant section. If the concentration is not 50/50 (protection to -34° F [-36° C]), drain some coolant and adjust the concentration. It may take several drains and additions to obtain a 50/50 coolant concentration. Whenever coolant has been added, the coolant level in the coolant reservoir should be checked the next few times you drive the vehicle. If necessary, add enough 50/50 concentration of engine coolant and distilled water to bring the liquid level to the proper level. 249 2007 Montego (mgo) Owners Guide (post-2002-fmt) USA (fus)
