Okay, here's the deal. I'm in the middle of converting an '82 245 from diesel to a gas engine car as some of you may know. Part of this conversion requires changing the cars' inside wiring harness which runs mostly behind the dash (I'm also upgrading the engine harness ). Since I have the dash and the wiring harness out and am installing a new heater motor, resistor and switch because I never want to have to go into that again should I go ahead and replace the heater core or would it be just as well to get the old one boiled out? I don't know the condition of the old unit ie: clear and functional or plugged or somewhere in between. I've heard that changing the heater core is one of the worst jobs on these cars and wonder if it's thta bad considering wher I'm at with this. I just really, really, really don't want to have to go in there again. Thanks

    If you "boil" out yours or replace with a used one you run the very possible risk of doing it all again soon. A heater core that old just HAS to have some corrosion of its tubes. How thin those walls are is anyone's guess, but....

    My son's leaked a tiny bit - the rad shop said not to even think about trying to repair it. A new 4-Seasons from FCP ($95, 2 years ago), MANY hours of work, and it's blowing hot, dry, (and quiet with the new motor) and should for another 25 yrs.

    get a junkyard one and install it. with the dash out it's no trouble; it is an awful job otherwise. I would not pay 100 bucks for a new one; if you want to go new, get a 5/8 inlet/outlet one (Dodge ones work) and put it in.

    I haven't seen any reports of leaking heater cores; it's always a blower motor bearing failure that requires the long tear-down process. If you live in a climate where -10 F. is common, consider changing it because the buildup in the tubes will reduce heat transfer. If you keep it, check it for thin spots by applying 15-25 psi of air pressure. jp

      Trust me, replacing it now is worth it. Don't know how many miles are on the car, but the one I pulled out after 236K miles looked pretty nasty (no leaks though).
