This will not be rated low because it works just as well as a new heater core. As it should. Altough, replacing a 2002 Ford Taurus heater core was a little difficult at home. But we watched a video on it, and were good to go! (Had only done it once before to a different brand vehicle.) The dash pulling completely out was a trip to take on its' own! Once off, it fit like a glove, and had no problems with hook up or start up! Hopefully this product will last as long as the manufacturer's part!

    Comments about CARQUEST Heater Core:

    This was one of the easier heater core installs I have performed. It took under 2 hours start to finish. Clamp off the rubber hoses from the heater tube assembly to engine and remove the two hoses from the firewall side and then remove 7 bolts on the top and sides of the dashboard, as well as the glovebox door. Contrary to what is shown on YouTube about cutting out a medal tab, the dashboard can be pulled back far enough to pull the heater core out of the heater box.

                  For help with your project, I recommend getting a repair manual specifically for your vehicle. It should be able to help you with detailed instructions on how to do many things.

                  A:

                  I use a Haynes repair manual for my '98 Taurus but, in the case of this heater core replacement, many of the steps were not needed. Disconnect the battery as the airbags could otherwise go off. Drain the cooling system. Remove the lower air component cover-right side under dash-then the blend door actuator and heater core cover and gasket to see the core itself. In the engine compartment, back the two heater hose clamps off the core connects at the firewall. Pop off the 2 side trim covers on either side of the dash and remove the two heavy bolts under each. Remove the vent cover on top of the dash and the three bolts under it. Unhook the steering column under the dash. Put a little weight on the steering wheel to loosen the dash from its mountings (be careful not to pull too hard). Here's where you need a friend or a brace: lift the steering wheel just enough for the old heater core to be pulled out (have a plastic bag ready to catch fluid). Slide in the new core and reverse all steps.

              • Q:

                Is it necessary to pull out the dash inside as well as go thru the firewall to replace? What other products must be purchased to replace this core.

                  Yes on some vehicles you do have to pull out the dashboard. For step by step instructions i recommend that you go to your nearest Advance Auto Parts store and purchase a repair manual.

                  Hi everybody,

                  watch the video, you don't have to remove the whole dash,
                  just remove the bolts on the side access panels and then
                  the 8 screws from the top vents, gently lift up and out about
                  4" and you're good to go. the video shows the easy way.

              • Q:

                I have a 1999 merc sable. When i use my air (and sometimes even without air)and come to a stop light my temp gauge goes up to hot side. I have to shut air down and put engine in neutral and rev engine to make temp go down. I had my radiator flushed not long ago. I was told my heater core could be restrected from a good water flo. Please let me know if that sounds wright. I just changed my thermostate a few days ago.

                  Depends on the vehicle and the person doing it. Could take a couple of hours or it could take a day or two. A skilled mechanic should be able to replace one in a few hours.
