If your coolant is full, and the car is not overheating, it's probably not your thermostat, but you might want to make sure. Look on the heater hoses running to the heater core - there should be a solenoid valve in the supply one (I think it's a vacum solenoid). That ****** is probably toast.... I believe it's meant to shut the coolant flow off when the aircon comes on. You can either whack it, replace it, or, if the aircon doesn't work anymore, remove it and put a coupling in there.... if it's not that, then your heater core is probably plugged.

Hope this helps :)

what is needed is not worth it.getting new motor is cheaper.

SOURCE: need to know which fuse?

there is a box under the hood on the right side near the windshield when facing the car, there are two plastic screws to undo to open the cover, on the inside of the cover are the placement of the fuse schematics

It should be right there on the hood it should be yellow or white (Vehicle emission)

Personal experience between 13 - 20 for most models with the v-6 and v-8. the 5.7l is about the most fuel efficient at roughly 17
