spark plugs and wires are as easy as a oil change. no way id pay to have them changed. all you need is a 3/8 th ratchet, a 5/8 th spark plug socket and a 3 inch extension.

Thank you! The video I watched made it look pretty complicated

It's easy....except for the psgr rear plug...atleast on my 2001 5.3 motor.

That was a pain and next time I will spend time to research tips for that plug removal.

Word on the street is that GM "certifies" the engines, etc. for 200,000 miles. I ran mine down the local 1/4 mile drag strip to hit 200K then took it home and pulled the motor for a refresh, cam swap, etc. Power, compression and oil pressure was great, just had a noisy lifter at startup. Inside the motor, the timing chain 'looked' fine and the oil pump still showed it's machining marks on the inside. The pickup tube O-ring was still holding together but was collapsed. Cam bearings were fine, cylinder walls looked good...

I say just maintain it to the best of your abilities, which includes keeping an eye out for possible hints of impending failure.

Thank you! Nice to know the inside of your engine looked that good. I would like to replace it someday with a vehicle with about 2,000 lb more towing capacity...but it's hard for me to make that change when my Yukon is still running so well. Thanks again!

Gives you a little more assurance, huh? My point was that 200,000 miles on these isn't anything to be overly concerned about if it's been cared for. Mine was well-maintained and driven easily the first 147K miles of it's life. Then I got it and have been giving it a firm whooping pretty much every time I drive it for the past 53K. Still maintaining it to the "T", though.

Thank you! I love hearing things like that. This is by far the toughest vehicle I've ever driven!

2004 Denali. 6.0 engine. I bought it 5 years ago with 90,000 on it and have maintained it meticulously. It had a great service record with the 1st owner. I had the transmission rebuilt 2 years ago, have replaced almost everything in the susepension and replaced the alternator and fuel pump. Yep, I've sunk some money into it, but it's still cheaper than a car payment haha.

This summer we're hoping to take a long trip with our trailer. I think the spark plugs might be original.

Does anyone have any thoughts about things that should be done at 200,000? I'd prefer to replace anything that commonly needs to be done at this mileage while we're at home instead of somewhere along our trip.

Thanks in advance.

Hey Dan, REPLACE THE DAMN CHARCOAL FUEL FILTER ASAP! That damn thing is up under the rear axle and spare tire. It won't give you an ounce of warning, then the truck just stops!!!! A road repair would be a mess. Don't forget to have a wood cone dowel to plug the tank so you don't dump gas all over you and the driveway. Seriously though, if you think it's original, CHANGE IT!!! It's a royal PITA!

I'm the oddball here, but I bought my '05 new in Feb '06, and it still has the original MAF, plugs, wires, and radiator. Still runs like a top at 215,000 miles.
