Most Liked Positive Review
I would buy again
Fit perfectly in HVAC unit. The inlet and outlet ends do swivel to nearly the perfect position. The inlet and outlet ends were not bent at a sharp enough angle to easily fit through the firewall. End result is I have heat and no leaks.
Most Liked Negative Review
Meh...
While changing the 03 Dodge Ram heater core was nonsensical, the part did fit right. The one I replaced looks like this one where the ends are adjustable--ironically, the last one leaked at these points, so we'll see how this one pans out. Cost effective, but I question it's longevity.

Not a good fit. Stay away. Go oem
Verified Buyer -
This does not fit into the molded plastic that the tubes lay into. I returned it and bought from competitor store. Also ran into same problem. I did eventually find one that kinda fit. Wish I would of went oem. Go on you won't regret it.
absolute garbage
If you like tearing your whole dash apart twice a year please buy this! It will last about 4 months and start leaking again. ZERO STARS!! NEGATIVE STARS!!! WASTE OF TIME
Bottom Line No, I would not recommend to a friend
JUNK
Bought this heater core when mine went, 3 months later I'm having to pull this carquest heater core because it is already bad and leaking all in my floor...
Bottom Line No, I would not recommend to a friend
Direct fit. Appears to be well constructed.
Verified Buyer -
Perfect fit, and has the foam seal already installed. In the picture, the foam is not present.
Buy again
