heating on 1997 Mercury Villager
Asked by Visitor for the 1997 Mercury Villager
The 3.0 lt nissan engines are hard to remove air pockets from the cooling system. I use an air lift system for refilling, which puts the system under a vacuum before filling with coolant. You can try filling then running till operatinng temp, leting it fully cool and repeat over and over.
