    1998 Yukon low operating temperature

    Hey Guys, I have been reading here and I think I know what's going on now but looking for some clarification. So I got this thing from a guy who told me he had just put in a new radiator. The operating temperature is as shown in attached photo once warm. When I start it the temp creeps up to...

    98 Yukon 4x4 squeaky on cold start

    The 98 is doing great. Only issue (well besides the minor ignorable ones) is it has recently started squeaking on startup. See video. Anyone know what that is?

    Three random shut offs while slowing to a red light.

    So on my 09 Yukon I just had my 3rd random shut down while driving this year. Two times while I was slowing down to a red light. Pop in neutral and turn key and fires right back up like nothing is wrong. I read a while back that could be due to the battery cables (negative?) going bad and that's...

    2009 Yukon SLT XFE ride rough, body mounts?

    Quick back story, I bought this new in 09. Traded in 11. Another local businessman bought it and had it for 10 years. I told him I wanted it back when he was done with it. I bought it back in 21. Unfortunately his hunting camp was down some washboard clay road and beat the shit out of it but...

    Rear air acts funny after battery disconnect.

    A while back I disconnected battery for something and noticed the rear air was coming out of the vents by the rear evaporator. After a week or so it started working normal again. I also noticed that the DIC outside temperature reading was wrong for awhile too. Fast forward, I just had it in...

    09 Yukon rear window washer fluid sprayer

    Everything works on this thing except the rear window washer fluid sprayer. I can hear the sprayer motor but no juice on the glass. Yes there is fluid in the reservoir. The windshield washer on front works great. Anyone have any ideas?

    How do I know what transfer case I have? This is the only label I could find. 98 Yukon 4x4.

    Button has the 'Auto 4HI' button but I think its an aftermarket switch panel. I understood that the 98 4x4s with "Auto 4Hi" push button 4wd take AutoTrak II fluid. I bought the fluid but have been holding off changing fluid because I want to be sure I got the right stuff. Can I find the exact...

    "Honk" sound when stepping on the gas?

    Im surprised I haven't found any other posts about this when searching. I had a 97 Tahoe 4x4 in 2001 with 80k on it and when I hit the gas hard from a stop, it sounded like a honk from the back of the truck. Others heard it and would mention it, but I didnt think much of it. Figured it could...

    G80 code fluid change, additive or no?

    So in my 98 Yukon with G80 code, I have a rear axel seal leaking and am going to service rear end. Bearings, seals, fluid, gasket. From the AMSOil site, I have two quarts 75w-90 (ACD 10-4016) in my cart (ACDelco fluid, just using AMS site for amounts) but am conflicted if I need to order and...

    98 Yukon 4x4 steering wobble at 50+

    I picked up this super clean 98 Yukon 4x4 off a guy. During the test drive I knew it was shaking but I was guessing a balance issue. I got it aligned and balanced and its still there. I watched some youtube and apparently its an issue with the steering. Which is fine, I expected to put some...

    Shifter cable bushing gone. New one or zip tie?

    First under carriage inspection. My neighbor has a lift and I put up the 09 today and started checking everything out. The shift cable was just hanging on as you can see below. A doorman new bushing is $19 and they have it at oriley, BUT I have a zip tie right here for free. Is there any...

    Rear Bump Stop for 2009 Yukon XFE?

    It seems this XFE thing throws me off in search of suspension parts. @915_Tahoe, would you be good enough to tell me if the rear bump stop for my XFE is 15039397? Vin is 9R218071. Thank you brother! I went to gmpartsgiant.com and it says that 15039397 IS correct for a 2009 Yukon 2wd but when I...

    2018 Yukon SLE - Air blowing room temp air

    Warranty just passed of course. I had a 2015 that had the a/c gone out twice. They said it was the refrigerant lines cracking from too much stress. The second time they said a new bracket had been installed to take the stress off the lines. Now 2018 air not working. Under the hood the...

    Strange clicking... Possible exhaust leak?

    So I have a 15 Yukon I got in Aug 14. Shortly after I got it I noticed a clicking noise when its idling heard from the outside. Its loud enough that people comment on it and say things like "should it be making that noise?" and "that motor sounds funny." I have taken it to the dealer and...
