Whole dash has to come out. Has anybody had any good experience with sealer poured into the rad? It doesn't leak on the floor...yet. [Reply]   [No Email]

Had to change the heater core. Dash has to come part way out, mostly on passenger side. Splice new heater lines to old ones coming thru firewall. On a V10 they say pull the passenger side cylinder head. Not me. 3 hrs. start to finish. [Reply]  [No Email]

That is what my mechanic says. [Reply]  [No Email]

I had the heater core replaced in our 1981 Mercury Cougar about 20 years ago. It wasn't cheap back then and I had the dealer to replace it. Now I replace the antifreeze every other year in it. One gallon of raw antifreeze will make 2 gallons of 50/50 mixed antifreeze. It will lose the rust inhibitor. Permanent doesn't mean forever it won't boil away like the alcohol called Zerone we used back in the 1940's & 50's. We didn't have any heater core using it. We drained it when the weather quit freezing. Hal [Reply]  [No Email]

The chevy was an easy fix and I did it myself. The f150, not so much. I just routed around the heater core. It sold pretty easy that summer because the A/C didn't have to deal with the heater core warming up. [Reply]  [No Email]

You can fix the leak but at what cost? The $400 to replace the core or not having heat? [Reply]  [No Email]
