    AC Troubleshooting 1976 GMC C15

    I'll give that a shot. I'll need to get a new condenser in order to allow that though. Thanks for your help!

    AC Troubleshooting 1976 GMC C15

    It's in the evaporator core. New valve too. I think I may have figured it out finally! There is about a 4in gap between condenser and radiator. No electric fan. I think that is causing it to not dissipate heat correctly. When moving and driving, it cools great. Stopped it gets hot and...

    AC Troubleshooting 1976 GMC C15

    Update. I found out I had the discharge and liquid lines flipped on the condenser. Dumb mistake but you live and learn. I now have #8 discharge going to top of condenser. #6 liquid line going to evap core. And #10 suction line to compressor. Problem is, after putting 24oz of r134a in, it still...

    New to the square body scene

    Welcome from Texas! As others have said, rebuild your current carb. If it's original and a Quadrajet, they aren't that difficult to rebuild. I got a kit from quadrajet power that included everything and they have videos on how to rebuild so you can follow on step by step easily. I'm also a...

    tailgate/cab band trim repair

    I know the tailgate panel is anodized so polishing won't work unless you remove the anodization. I used a cheap spray in oven cleaner, let it sit for a minute, then brushed it with steel wool. I clear coated afterwards and mine is holding up fine. No clue on removing dents. I'm not a body man...

    WTB '83/84 GMC dual headlight grille

    If I hadn't just got everything switched to GMC on my truck finally, I would sell you the one I just picked up.

    Do the magnaflow straight through mufflers count as glasspacks? If so, I've had them on my truck for a decade and love them. The sound matches the era of these trucks so well.

    What have you done to your square lately??

    It's a new switch. Is there a way to test it? When filling it up, it does cycle until it has more freon. Then it freezes up at the expansion valve but remains cool (not remotely cold) on the drier. Pressures also tend to be high in high side relative to where it should be compared to low side

    What have you done to your square lately??

    Finished installing fender badges and dash badge. Officially showing GMC rep now! Also bonus pic of engine. Still struggling with AC freon not flowing through orifice tube properly and freezing up. May just give up and take it to a shop at some point. Will be the first time this truck sees a...

    Has anyone used an Edelbrock Rochester Quadrajet carburetor?

    I've been using an edlebrock quadrajet 1901 for nearly a decade. Runs fantastic. Like all quadrajets, you need to fine tune a little bit for your application but once you have it set up, you are golden.
