Have I Gone Bankrupt Driving My 8.1 Liter GMC Yukon 2500?

Having owned many GMT800s, I can confirm his lack to fear towards taking this truck on long road trips. This rig is more reliable than most new cars, even with 300,000+ miles

yup, i can attest to that. I have owned 4 GMT800s and never had any major problems with them. My dad had a 2003 single cab 4.8L 2wd that he would use for work and got that thing to right around 340k miles!

We owned 3/4 ton Suburbans from 2000 till 2020. They actually made the 3/4 ton package until 2014 when it ended with GM900 platform. The 2015 and up was only available as a fleet or government package and are extremely rare. The last one we owned was a 2005 that we had converted to diesel using a 2006 LBZ Duramax with the 6 speed Alllison transmission and 10.5" HD Rear Axle. The Diesel made it absolutely the best SUV on the planet. It towed our 38 foot Travel Trailer, took the kids to School and was just a great all around family vehicle. Plus, it was just the coolest rig that everyone asked about when sitting at the Diesel Pump.

[@alale923]

My dream Off-Road/Camping/Hunting Rig is a GMT800 with a 6.6 Duramax and a 6 speed (or maybe 10 speed?) Allison, and also Quadrasteer even though I am WELL aware of how much of a pain it can be the system is just like the rest of the truck. ie- Looks/seems complex but the tech is old enough to be robust, but new enough to be luxurious too, and if you can turn a wrench you can be back on your way.

[@meadmaker4525]

I owned a "GMT800" in Polo Green with a tan leather interior. What a magnificent truck!! It wasn't perfect, but I truly loved it. Probably the most comfortable ride of any of the trucks I've owned (which is many). The owner is right, you just don't get comfy seats like those anymore. All the seats in the newer trucks nowadays are too small and too firm. You notice how slim the center console is in the GMT800? That's to make room for the extra width of those fantastic seats. Still sad I got rid of mine, but it was having transfer case issues and I couldn't afford the repair bill at the time. Just looked online and one exactly like mine (1 owner, less than 60K miles) just sold for $24K. I think people are starting to remember how good these trucks really were and they're starting to command more money for good examples. Also, the Vortec 8100 was a monster. Absolutely loved the effortless power.

I do remember driving it when I was first learning how to drive and it was pretty easy. Eventually my older siblings moved out and we no longer needed this large SUV but it was great when we had it. I think we average to around 11 mpg something like that. When my parents bought it though gas was like $.95 or a dollar at the time.

[@surfride101]

that clicking is likely a blend door actuator. I have an 05 duramax since new. Over time, the grease for the gear/stepper motor compromises the potentiometer causing the HVAC control module to lose visibility as to the position of the doors; there are modules four... the fresh/recirc is the most difficult to r/r so I replaced this unit and cleaned up the others (2015), the only unit to fail again was the dorman (meidiot) for the recirc door, went back to ACDELCO on that one. If you have a decent scan tool you can go into the hvac module and observe commanded v actual for the counts of each blend door. This dash is a snap to r&r. Other common failure is the stepper motors for the gauges another simple DIY fix as well, steppers are available on Amazon. MN plates made me sad, cannot imagine what the frame looks like.

[@mikesweet5848]

Can just send out stepper motors. But yeah that blend door actuator might not make that noise if you switch between recirc mode and external. They also have noisy ambient air temp sensors for the auto climate. They look like tweeters in the headliner.

To me this platform is much better suited for dedicated work trucks and vans considering the gas mileage is not justifiable if it’s not actively making you money.

[@rockymountainjazzfan1822]

The biggest weak spot to watch for if buying this generation of a GM truck is the A/C condenser or the heater core. When they go bad, replacing them is about a $2,000+ job because the ENTIRE dashboard assembly must be dismantled to get to them. That can easily run into 12+ hours of labor, plus the parts. Aside from the that, they are pretty bulletproof trucks. I've seen a lot of that generation of GM pickup still going strong after 300K miles of hard use. Don't expect good fuel economy, though. Even the 6.0 V8 in the HD pickup was only good for about 15 mpg tops, often down in the 10-13 mpg range.

I do like it, sucks the gas but will tow anything

[@rambo4war]

I’m guessing I’m a little late for the Overland Expo?

[@goodlife1500]

I found one the but the MPG is scary with current gas prices

[@johnnorvaisas]

I found a 2004 Motorhome with the 8.1 with only 18k miles I'm looking to travel the country and live in it. Is this engine worth buying? I'm more of a Ford guy but this 8.1 is really nice.

[@RandalColling]

I have a 2003 Suburban 2500 LT 4x4 with a 6.0L. 158,000 miles. Bought a 2022 Tahoe for the wife. I prefer the 'Ol Sub.

[@Kotaztrafee]

Put it in tow mode with overdrive off then smash the throttle.

[@Longneckmexican]

Got an 04' Silverado 1500 cateye 4.8liter V8 4l60e 243,3xx miles bought it july2020 with 186k it's my daily drive the piss out of it

[@afarrell10]

Why not put a LPG/Propane system in it? Popular in Europe on big petrol engines.

[@simonorr594]

I know, but propane is the same price as US gas!

[@shitloveaduck]

It’s a pain in the butt and there’s no savings when you figure in the costs and less efficient the motor is.

Did I miss what year this Yukon XL was?

[@kevinlogan2306]

I have 2001 Yukon XL 2500 with a 6.6

[@motofunk1]

Just carry an extra fuel pump, crank position sensor and a spare alternator.

[@3wrapframe]

The next gen suburbans sure did have the 3/4 ton with a 6.0 and were loaded too… just not very common.

[@R.Nelson]

That's an Awesome truck!! 8.1... So that's a 454 cu in motor? Nice truck!!

[@WheresHerb]

[@Jorgrbryce16]

[@NWI_Steel]

496

[@shitloveaduck]

[@R.Nelson]

@@WheresHerb Thanks!!

[@Ceo8203]

Mine make the same noise behind the dash

[@wmkess]

How is the ride on these? I’m contemplating getting a suburban or XL of this generation. We have a much newer XL as the main family car my wife drives so this one would just be a second vehicle I can use to haul 4+ kids in since my ext cab 04 Silverado lacks the space.

[@dannysmith9882]

A little stiff. I think they ride better than the 1500s of the era, which are floaty. The steering feel is well judged.

[@delbertlayman3693]

Looking for one of these. Hard to find in my area... .wore out or just not for sale

[@danhambrick6331]

Nice score Big Steve...💪👍👍
