Dat73z Posted March 22, 2016 Share Posted March 22, 2016 Hi all, After replacing every coolant line and the heater control valve I'm looking at replacing my heater core due to a pinhole leak. Does anyone have recommendations on a replacement heater core? I was looking at this unit from ZCarSource of AZ: http://www.zcarsource.com/heater-core-240z-70-73-new_8_56539_66436.html So far as I can tell, rebuilding my OEM heater core would cost a about 50-100$+ more locally so I've been looking at replacement options. Thanks! Quote Link to comment Share on other sites More sharing options...
Kurbycar32 Posted March 22, 2016 Share Posted March 22, 2016 My experience is that the "new" heater cores from regular parts stores are mostly junk. I suspect that maybe they were rebuild 20 years ago and then rotted in a warehouse. I went through 4 "new" units from 2 different auto parts stores that were all badly corroded before ultimately getting mine rebuilt at a local radiator shop. I cant speak for Z car source but if they get their parts from the regular parts chain I would skip it. My local radiator shop did an excellent job and I don't regret it.

Dat73z Posted March 23, 2016 Author Share Posted March 23, 2016 Thanks, that seems like the general consensus from what I've read. A recore and sealing up the endtanks may be the way to go here. Quote Link to comment Share on other sites More sharing options...
