What did you do to your NNBS GMT900 Tahoe/Yukon Today?

[Doubeleive]

All this wiper arm talk reminds me. I tried to take off my driver's side arm. I took the nut off but the arm is frozen to the stud. I need to find a small puller to grab it off or something.

ya and that's the problem most of us will probably run into if taking the arm off, I have a puller set not sure if it is small enough for my wiper arm though. harbor freight probably has some different sized ones.

Y’all got my curiosity up. I had to go take pics just now. Because who takes pics of wipers.

Yeah I got a couple big pullers but I don't want to fumble around the windshield and break the fkg thing ya know? The only small puller I have is a 3 jaw.

Just snuck a driveway oil change in over my "lunch". Don't tell my boss.

But, as I was standing there watching Asplundh massacre the limbs along the power lines while waiting for my oil pan to drain, I was thinking about yesterday doing the water pump, and part of my mysterious coolant loss issue. The radiator was 100% leaking at the weld, but in this photo the block looks really crusty where the water pump would obscure your eyes.

Is this how a nine-year old iron block would look? Or, do you experts think there could have been a leaky water pump gasket or two?

In any event, after buttoning up the oil change, I went for a little 5 minute drive to get it up to temp and adjust the coolant level (I didn't quite top it off yesterday). No oil or coolant leaks, but while under the car I did see signs of the ATF coolant lines having a little weep at the gasket that mates to the transmission case.

PS: I have the new lines waiting to go in, but I just need to pull a crossmember out to make enough finangling room for that long cooler hose.

PPS: Where can I find that tiny grey plastic clip that holds the two electric fan power wires in the black harness clip? (You can see both harness connectors at the bottom of the pic, but the one on the right is missing the piece in question)

I blindly pulled the grey piece off the parent black part yesterday, and lost it somewhere on my driveway. (I assume its in the land of 10mm sockets)

one of mine was broken or missing at some point and I don't remember if I got it from the dealer or found something at the auto parts store or ordered it online it was one of the 3 lol

Just reach back to the 90s and clip ya on a set of wiper arm louvers

I have used this in the past on other vehicles. Not absolutely positive that it fits the Yukon, but I would think it should.

I think one of those battery terminal removal tools works. I know Lisle 54150 is used for battery terminals and wiper arms

I had to order one of these to get my broken rear wiper arm off. What a PITA.
