  • I HATE replacing heater cores!!!!

    On the 1st beautiful day of the year guess what I get to do? I have been putting this off for 2 years now because I know what the job involves. The motor is ready to go back in after a 10 month wait at the rebuilders. So I figured it was now or never on the heater core. Luckily I didn't run into any issues and did manage to get the fender lined back up reasonably well.

      Dave, those inner fenders always get in the way when removing the nuts that hold the cover. I read about a trick years ago that really works great. A 1 inch hole saw. I did this on my first 65 Chevelle. One hole in the inner fender allows you to put a 1/4 inch drive socket right on the nut and saves hours of labor. On my current Chevelle I also did that trick on the drivers side inner fender to allow easy access to the nut that holds the clutch cross shaft on the frame bracket. Neat old Poncho.

      I hope yo had a jack stand under that car. At the very least put the wheel and tire under the frame.

        I've always been convinced that the heater core is the first part on the assembly line, and the car is built around it.

          You replace the heater core on a '68 Tempest/GTO from inside the car? I have had one for almost 30 years and had them before that, bought and sold a few more since. Even doing the blower motor you just remove the inner fender or take tin snips and cut an inner fender door/hole on three sides and fold it down to get access to the motor then fold it back up and reseal it with body sealer when done. The one inch holes for wrench access previously mentioned and the inner fender cuts are GM dealer service bulletin techniques.

            About 15-20 years ago I replaced the heater core on my '89 Taurus SHO. I checked with the dealer first, and their book said it was 9 hours labor [that was for someone who knew what they were doing] . I was in no position to part with that much cash, especially when the part was only about $60. It took ME 3 days. I did it, but what a nightmare.
            A lot of that time was spent numbering and photographing the wiring harness and things as they came apart. Glad I did it though, as that 3 days was spread out over about 2 months as other life situations got in the way and I would have forgot the exact order in which things had to go back together. I would rather change a motor, than do that again.

              Hey nothing on those car was easy. Helped a friend do a starter. What a nightmare we ended up cutting a hole in the inner fender so we could get to it and the bolts. He sold it right after that.

              I replaced a few heater cores back in the days when I was able to work on my own cars. They do not compare to replacing the air conditioning unit in an Audi R8.

                  That's why they call this the lounge. Have a few toddies and you never know where the conversation may lead.
