What's new

What did you do to your GM today?

Swapped mirrors on 05 to tow mirrors. Found that 12 point 15mm deep socket will fit torx nuts on front seats of truck. Did not have one here. It is at garage.

Yanked the tank in the 91 burb. Swore it only had a couple gallons in it but of course I was wrong. So I broke out the handy dandy spare electric fuel pump to drain it.

New pump and strainer. The old pump was made by Carter and the upper hose clamp that was made of plastic had fallen off. Was hoping for clearly degraded 2-in rubber hose in there.

GM Workhorse W22 Chassis, 2002 class A coach. Have been having AC issues with a leak that takes several months to evacuate the system. Took it to the shop for the third time; first time was to charge system, second time was to recharge system and add dye, this time was to use a leak detector. They did a leak test and at least found it, it's the evaporator. They only got into it enough to diagnose the issue. Shop said they can't locate a replacement part. Shop owner also said he really doesn't want to deal with it because I can do it myself, it's a big ass vehicle taking up space, it will take days to locate the part, and his tech's always end up breaking something else on the older coaches. I appreciate his honesty, it's the only shop I ever take vehicles to I can't fix myself.

I had them charge the system one more time because I'm taking it on a month-long trip starting Wednesday. When I get to my Arizona property, I'll add a can of Red Devil stop leak and see if that helps. Brother is recently retired senior service writer for GM dealership, and is sure it's a GM part, maybe out of a full-size van. When I get back from the trip I can pull the dash apart, remove the evaporator and get a part number. I'll replace it myself, then have the shop charge the system.

Every "Workhorse" part I have had to replace so far has had a GM part number or been a GM part. The Workhorse labeled parts are two to three times the cost of a GM part. Plugs, wires, coils, ABS sensors, most recently O2 sensors, and even the turn signal multi-switch. GM used that same switch in dozens of models. Workhorse part $149.00, GM aftermarket $24.99. The O2 sensors were Denso. A Workhorse based online vendor wanted $150 each, and when I called them about the part numbers the tech said I could get the same Denso or AC Delco parts off Amazon for much less. He was right, they were $28.00 each. He also gave me the updated version part numbers. Not a very good salesman, but an honest one.

And, it passed smog. I was a little worried because I had a O2 sensor fail on the way back from the last trip and I limped it home from about 100 miles out. Not much choice as no one seems to have parts on hand anymore and I was in the desert. I changed both sensors for updated versions, cleared the codes, drove it around the block and parked it for a month. Not the best scenario for a smog test, but they checked it with a code reader before attempting the smog check and it was clear.
 
Been prepping Big Blue's block for dropping off at the machine shop. Hoping to get all of that started tomorrow.

Most of the block plugs came out decently easily but these 1/4NPT water jacket plugs both decided to be ****s.

Swapped hitch from 2in to class 5/ 3in reciever. Hope the frame holds up. Hauling the 580B was a little iffy . Thinking springs are in the future.

Where can I find the u shaped wire? piece that attaches to the hood and engages the hood latch?
 
If you
I’ve probably extracted 50 broken studs from cylinder heads over the years with a 100 percent success rate welding on a nut. I thought this cock fag was gonna break my perfect record but I fucking got it!

If you weld a washer on first and then a nut it’s much easier to get a full weld on the bolt (and pump a bunch of heat intoit) before you just weld the nut to itself.
 
Im in the same boat on my crew. The back p-side ex bolt on both of them are busted and the block in my shop is a good 1/4" below surface.

Ive got a pretty good history welding nuts as well but this is pretty deep in there.
