    2012 Yukon XL SLT1500 Rotors & Brakes

    Looks like it's time for hubs now. Go with these Timken's or OEM Timken SP500301 Front Wheel Bearing and Hub Assembly https://a.co/d/8wl1eJi

    Leaking Coolant

    I had already done the other radiator hose a few weeks ago. All hoses, thermostat, and radiator are OEM.

    Leaking Coolant

    Installed the OEM radiator and thermostat and hose today. Install went flawless. Very easy install since the radiator is an exact drop in replacement and doesn't require installing ports, swapping bushings, etc. Only mistake is I forgot to dilute the antifreeze. I'm hoping this is ok since I'm...

    Leaking Coolant

    Ok I'll purchase another one. If I have the Yukon XL with transmission cooler, is there a recommended aftermarket radiator, or just go with OEM, which I think is AC Delco. Should I go ahead and replace the thermostat as well?

    Leaking Coolant

    Almost overheated the other day. Checked coolant and it was low. Filled it up and about a month later low again. Today I looked to see where the leak was. Looks like it's coming from the port on the radiator. Such a small leak though. Do I have to replace the whole radiator or can I seal it with...

    I'm going to order those. I only went to the dealer yesterday because I needed it asap.

    Busted hose P1258 P0117

    Either way. Hoses replaced yesterday. Bought both hoses for just under $200. Antifreeze filled up again. She seems to be driving good now. I think I'm going to replace the belts now just as a precaution since I don't know when they were changed last.

    Busted hose P1258 P0117

    It was definitely 100% after I left for the oil change. I'll have to check the dip stick but doesn't seem right. 0% would almost be impossible.

    Busted hose P1258 P0117

    Driving today and couldn't accelerate past 20mph, very headstand in accelerating as well. Got home and smelled antifreeze. Turns out it's a busted hose. The bigger question is why does my oil read 0% when I just got an oil change last Thursday???

    2012 Yukon XL Autoride or not

    It appears I have it. Since I bought the truck with 140K, I've never heard the compressor kick on. Time for some troubleshooting but more than likely I will replace all shocks, struts, and compressor.

    2012 Yukon XL Autoride or not

    I looked at purchasing the Eibach Pro-Plus Lowering kit and while configuring the order there’s an option for Autoride and w/o Autoride. How do I tell if I have it or not? Certain code in the VIN?

    2012 Yukon XL SLT1500 Rotors & Brakes

    Actually went with the Bosch QuietCast rotors with the Akebono pads. Discovered yesterday that one of my sway bar links is broken. Replacing with Energy Suspension is the general consensus or OEM? As with other bushings, etc mentioned above, yes I will eventually get to them.

    2012 Yukon XL SLT1500 Rotors & Brakes

    My '12 Yukon XL has reached about 160K (acquired with 140k) and it's time to change the front brakes. I've decided to purchase the GM OE front rotors and pads. I was able to find the rotors: 22950036, and Front brakes kit: 19369415, at GMPartsGiant, and looking to do the work myself. Other...

    Still leaks after 3 "fixes"

    I'll keep it in mind. Let's see what they say tomorrow. Also, I've been servicing this truck at a Chevy dealer. Would there be any reason to stop and start going to an actual GMC dealer.

    Still leaks after 3 "fixes"

    I am beyond frustrated. Back in Aug 2021 my 2012 Yukon XL started leaking oil. Brought it in for service and they fixed the leak, saying it was Oil Cooler Gasket. Brought it home the next day and noticed oil in the same location. Brought it back and they said it wasn't tight enough. A few months...

    2012 Yukon XL Oil Pressure switch code even after replacing sensor

    Yes, I clear the code every time it comes up. What is interesting is that I didn’t see a filter when I removed the old sensor. I even removed the new one once because after reading some posts as read about the filter and realized I may have forgotten it. I even tried with a pick to reach in the...

    2012 Yukon XL Oil Pressure switch code even after replacing sensor

    2012 Yukon XL SLT1500 with about 138K miles. So, I got a P0521 code and according to the scanner and app it’s the Oil Pressure Sending Unit. Well, I replaced the switch/sensor last week and I’m still getting the code. The oil pressure gauge on my dash generally is at 40psi and fluctuates to...

    2012 Yukon XL SLT 1500 ABS question

    So the million dollar question is where is the brake switch on a 2012 Yukon? I don't see anything that looks like the part I bought.

    2012 Yukon XL SLT 1500 ABS question

    Looks like it’s the brake switch. C0161 code. Symptom seems to be consistent with a “Stuck in park” video I saw on YouTube

    2012 Yukon XL SLT 1500 ABS question

    From the wife “Drove the truck, everything was fine. Pulled in to parking lot, turned off truck (AC was left in on position), exited the truck. Shopped. Came back to truck, got in and turned it on. Started fine, no issues. Put truck in drive and proceeded to go forward to exit the parking spot...

    2012 Yukon Service

    Just called the dealer back and they said they checked those and they didn’t need to be changed. Does this sound legit? Sent from my iPad using Tapatalk

    2012 Yukon Service

    Interestingly enough they didn’t recommend the power steering or the differential, transfer case after they inspected it. It is a 4x4.

    2012 Yukon Service

    Heading to the dealer to have my 2012 Yukon XL I recently purchased with 137K fully inspected. At a minimum I’m having them flush the transmission fluid, coolant, flush brake fluid (if necessary), and perform a fuel injection cleaning. Anyone recommend anything else? They said they will inspect...
