Not the same form/fit/function as the original. Cross-section of the bottom pan is rounded-square and does not fit into the heater/ac module, which has a true round profile. This same part number is made by several brands (all are the same).

            The product worked exactly as it was supposed to work. My original Heater Core went out making it impossible to drive my vehicle. I did not realize the importance of a Heater Core until I was driving down the road and steam started coming out of the vents in my car and all of my windows fogged up and I then realized that the Heater Core was completely out and had to pull over and find a way to get my car to the shop to get the new Heater Core put in. The Heater Core plays a vital part in the cars performance and you can not drive with out it.

                Bottom contour is squared off, GMC is round. Does not fit in well due to bottom contour. Sticks up out od well about 3/8" Because it was 10PM and I needed vecicle in AM, I had to seal top of well with weatherstripping. Heater core works fine but is not a exact replacement.
                Beware, heater core replacement in a Blazer is a muther of a job and you have to be very mechanically inclined for this job!!

                    Comments about CARQUEST Heater Core:

                    Since I have a warranty on this incompatible part, I am going to get a new one. It will fit into the cavity, but the cover for the heater core wont be able to seal the top -causing an air leak. This will reduce the efficiency of the heater core's functionality. You can try to seal it with foam, etc.. Since I am an automotive tech, I can easily replace this, HOWEVER, if you are going to do this, and you don't feel like dealing with the b/s of the improper fit AND short life of this heater core, DO YOURSELF A FAVOR and spend a little extra for an OEM part!! These other "negative" reviews were correct!! It doesn't fit correctly and it doesn't last long. Oh yeah, get yourself some foam strips as indicated by other reviews. The original core has them for a proper fit and probably to prevent "chafing" as well.
