Question type: Maintenance & Repair

Don't know how to switch out the heater core, can't afford to take it to the shop. Anyone have any advice or tips for this problem?

1 Answer


Never had the pleasure to do one myself, joking of course . you could check the limited help offered from the small shop manuals sold at parts stores, about 17 $ look in index first to see if its covered, some can be a nightmare, the last one I did was a Lincoln mark7 a total nut buster, next time ill buy 3 or four 12 volt heaters and wire them in for about 60$ an older car I don't care what it looks like
