Yeah unfortunately I am not savy on the system. I would love a diagram to see how everything flows and what could be a fail point. Like - is there a TXV or thermostat that could have failed?
2015 -Yukon XL Denali with 190k miles. Transmission overheated 2 days ago. Changed out the fluid and filter (overdue). Nothing remarkable on the magnet or in the fluid - just dirty.
Just drove it after the change out and temp was 225-250 and rising in 25 min of driving. Am I just screwed into...
I am trying to program new fobs and am having an issue.
I follow the steps in the manual and get to the part where the DIC says “ready to program key #”.
After I push the start/stop button nothing happens. The key is not programmed.
I have done this before with no issue.
I have a 2015 Yukon XL Denali that has a rattle under the center of the vehicle. Replaced the muffler, checked all of the heat shields.
Comes in and out at certain RPM’s. Shop thinks it may be the mid-exhaust flex coupling (piece circled in red) but on the Denali’s it is welded into the...
I have a 2015 Yukon XL Denali with stock rear air suspension. I need to replace the right rear ride height sensor -
1. Any reason to use something other than stock AC Delco parts?
2. Does it make sense to replace both left and right rear sensors at the same time?
Thanks.
Have a 2015 Yukon XL Denali with Magride. Doing a delete of the front magride (have all parts in hand) but I also need to replace the right rear strut that went bad. OEM part (84176675) is on back order.
What other options can I use for OEM and do I need to replace both rear struts at the same...
What is the software/firmware update everyone is talking about? I have a 2015 Yukon XL Denali that rides rough. I have asked about TSB stuff at my dealer and they say nothing doing.
I had both front struts replaced at 56k miles. Just got told they are leaking - 50k miles later. Ready to delete...
Yeah I was doing that with the muffler tech.
But if it was that wouldn’t it be speed dependent and not rpm dependent?

I was under the car on a lift with two muffler techs and a mallet. First they thought it was rocks on the heat shield but disproved they.
Only thing that seemed even remotely possible was a little bit of noise from the flex joint when struck by a mallet but not expected to be heard in the...
So I posted this before as a muffler rattle - but then I ruled that out after replacing the muffler so new thread.
I get a rattle (which I thought was the muffler) with the symptom listed below.
Ok. Back to drawing board on symptoms.
Not speed dependent but appears to be rpm dependent...
