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

    Finally got the air bag recall done at the dealership. Unfortunately, the "Service Air Bag" message still randomly appears off and on. Probably a loose sensor somewhere.

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

    Replaced the oil pressure sensor for a second time on my Yukon over the weekend. Holy crap, I forgot how much that sucks doing. My wrist and forearm still hurt.

    Oil pan gasket leak?

    So I finally got around to working on my Yukon this week. I replaced the O-ring on the oil pickup line, which seems to have solved my low oil pressure warning that was coming on. I also replaced the oil pan gasket and oil cooler lines gasket. This is the video I watched and followed that was...

    Oil pan gasket leak?

    Yeah, I've read to do both if you already have the oil pan out. I don't think I want to know about replacing the rear main seal. I'm no mechanic, I just do what I see on YouTube.

    Oil pan gasket leak?

    That seems to be the cheapest and easiest solution to try first. I just replaced those oil cooler lines and gasket about a year ago. But maybe a better gasket will do it.

    Oil pan gasket leak?

    I've notice the oil pressure fluctuating a bunch, a couple times it has gone down to zero and the "Stop engine" warning message has come on. I replaced the oil pressure sensor and screen about 2 years ago.

    Oil pan gasket leak?

    I hear you on that, I'm close to hitting 170K on mine. But I also think the leak is affecting the oil pressure. So I probably need to take care of it. Thanks for the advice.

    Oil pan gasket leak?

    Hey guys, I finally got my coolant leak issues fixed, now moving on to an oil leak. From reading various threads it looks like I need to replace the oil pan gasket. But I just wanted to confirm with people that know way more than I do. Pics are below. Or, let me know what else it could be...

    Another coolant leak help thread!

    Thanks, after searching the engine, it looks like the T connectors are the source of the leak! I couldn't tell which one was leaking but probably safe to replace both. Which parts would I need?

    Another coolant leak help thread!

    Thanks for the tip! After going up a little bit further, it looks like it might be coming from this hose.

    Another coolant leak help thread!

    Hey everyone, I'm hoping to get some help with diagnosing the coolant leak on my 2011 Denali. I noticed the coolant level was pretty low in the tank and filled it up. I went out for some lunch after and when I came back out to the truck, it looked like someone basically poured out a new bottle...

    Ordering correct transmission cooler lines

    This pic was from the passenger side. Those are the transmission lines that you see there. I replaced the engine oil cooler lines a few months ago. But it is a big mess.
