part installation went well....slightly larger than the original one...but none the less it installed...the factory that built the car...put two fasteners near the back....you might not get those back in to the enclosure. but it all still worked well....enjoy our turn......part is great........

Easy install and work great. This core is larger then the oem version so the screwed down clip doesn’t lock in where it should.

Fairly easy to install. Hardest part is taking off the black cover under the dash and getting the hoses to come off the old one. Overall, the quality seems good. Time will tell if it holds up. Took care of my no heat issue I was having on my Tahoe.

I installed my heater core today It went very well Fit right on in there just like the original I have a little leak on the outside under my hood from where the Tubes come out but that's not The heater course fault that's my horse's fault Other than that It's fantastic I mean I've only driven around today with it in I have a nice hot heater I know it does take a special hose On one of the The lines But I don't have that So I'm using hose clamps Best deal I ever found I didn't think it was going to be so easy Excellent price May just like the original thank you very much

Installed in a 1991 GMC C1500. Super easy to change. Does not come with foam piece to seal to hvac box. I just removed old one and glued onto new one. I did notice the inlet and outlet tubes rotate in the core body. However, i think that is by design so that you can manipulate it through the holes in the fire wall.No leaks so far.

showed up when promised good fit however had to make a new clip to hold core into place as the new header is thicker then the original
