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.
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.
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...
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.
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.
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.
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.
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...
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?
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...
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.
