Question about 2001 Mercury Villager
2001 Mercury Villager - Heat blows fine when driving but when stopped and idling it blows cool. I already had a new water pump, thermostat, and timing belt put in and radiator flushed. Still blows cold when idling.
You have an air pocket in the cooling system. To bled it out you will have to park vehicle on an incline or jack up the front end untill the radiator cap is higher than the heater core. The remove radiator cap and run engine until warm then hold rpm to about 1200 rpm's and top off coolant level until you have no more bubbles.
