How to replace a 1991 Lincoln Towncar heater core?


wow. just did this one today. all i can say is have patience. you just have to take the dash completly apart top to bottom. you have to lower your steering colume to. you dont have to take the dash out of the car when you get it off enough on the passanger side just tie it up to the handle at the roof and you got access to the black box on the passanger side. you have to go under the hood and remove two bolts and two hoses to release the black box so you can get the heater core out. you also dont want to forget to disconnect the battery and drain your radiator. I watched my husban do this and i dont know how else to explain this or give better detail i hope i helped.
