What did you do to your OBS GMT400 Tahoe/Yukon Today?

[TheAutumnWind]

Is it 2wd? Too bad it isn't the 6' bed.

Yeah its a short bed, 2wd, auto, and a v6... total grandpa truck. My moms father passed and gave it to me so I'm gonna try and keep it around for awhile and make it useful.

Lucky you!

Well ya know grandpa had to pass for me to get this old truck doesnt feel super lucky. But i suppose it is nice the truck isnt rotted away.

Never fails huh? I have that luck a lot lol.

Yup...plus I pulled/strained a muscle in my back so now it's really not happening for awhile.

I put one of a pair of $25 seat covers I bought at Walmart on my passenger seat. It was what you should expect from a pair of $25 seat covers.

Took my rear wheels off, checked to see why my rear passenger brake has been making strange noises, didn't find much. Cleaned them off and adjusted them up. Emergency brake is up where it should be again. Shame those adjusters don't actually work.

Speaking of that ebrake i am having trouble with mine. It doesn't come disengaged with the ebrake release. i have to blip the throttle to push through it, then it pops and seems to let go. Not using it atm.

Refurbed wiper arms. Replaced 10 year old wiper blades. Flushed the rad. Backflushed the heater core. Cleaned out the overflow tank. Replaced upper and lower rad hoses. My little man helped me out hes not a huge fan of pants.

Still needs the block flushed out. Ill have to yank the thermostat at some point and blow that out. It was so full of dex junk. All the water had evaporated and the dex turned to sludge. Its on its second round of chemical flush atm.

Took out the blend valve actuator that's been making weird noises and opened it up. Nothing interesting in there. I cleaned some dog hair off the assembly and it made less noise moving around than it did before. Probably coincidence.



Cleaned up the main power cable to the fuse block. Noticed a bit of corrosion on the bus bar. Will revisit it.



Just because I looked at them today, here's a before and after of one of the most satisfying jobs I've done over the past couple years that I still appreciate the difference today. Although they're nowhere near as clean as the pics, I still notice the difference. Soap and water, Scotch pads (I think I used light grey), aluminum polish, elbow grease, car wax. Nowhere near perfect, just cleaned up nicely.

Ok. Radiator is leaking. Is a 2 core 34" difficult to swap for the 28" single core?

Great job, looks new.

Great job, looks new.

Made the wheels look better/brighter from the outside, and less like a pos from the rear/inside too. I still like seeing them cleaner while I'm under it, as I often am lately. They had 20 years of crap on them and it took about an hour or two of hard work per wheel. Obviously only for polished/bare aluminum.

Put on a cheapo smoked led chmsl. The old one was toast and leaking. Sealed up with silicone. This will work for now.
