2008 z71 Tahoe Maintenance – what’s needed what’s BS

[07Burb]

so what about the Fuel injectors?

Run fuel injector cleaner through the system and call it good

At 50k miles, my dealer wanted to flush the coolant and replace (BS) and flush the rear differential and replace with new fliud (which I actually heard was not a bad idea).

I was also told to replace the belts, but they wanted like $200-$250 to do that and I can do it myself for alot less than that!

Other than that, I have a K&N Drop in Filter that I check periodically and that thing looks brand spankin new.

ok, so what do i actually need to get done at 60k?

anything not done at 50k + oil change? What GM "Recommends" and what should be done are two different things. You can probably go 100k without any maintenance other than oil changes and be fine.

I read that dif fluid, tranny fluid and brakes don’t need to be done till 100k... $ isn’t the issue.. Just want to do whatever the truck actually needs...

btw, all I’ve ever done is change the oil and I’ve had the truck for 4 years now...

Any and all feedback is appreciated...

I'd say the brakes need to be done when they need to be done. You have a larger offroad style tire which is going to have a higher rotational mass, therefore the brakes will need it quicker than what the normal life expectancy is.

Not only the dealer but a local shop that a friend owns recommended the rear diff flushed at 50k.

Tranny fluid should be good for 100k, as is the coolant flush.

Chevy recommends all that at 50k if I remember correctly, but wether you should actually do it is a whole nother' story.

Sorry I can't give definitive answers, only theoretical ones.

Monroe recommend shocks every 50k.

You've had the same air filter for 82k miles???? Is it the stock filter I'm guessing? I replace mine every 6k and it's really dirty when I do too.

yeah its the stock air filter. I live in Cali but im always on dirt roads its my hobby. lol. ATVs all the wayy. I just checked it last week and all looked good.

Follow the manual. What I did at 60k was tranny (dealer flush), transfer case, front/rear diffs, oil and filter, air filter, brake fluid. You can change all those fluids yourself but I would recommend getting the tranny flushed at the dealer.

I am sure the tranny flush will be discussed here... IMO if you do the tranny yourself you are only changing only 1/3 of the fluids. Also it will not cleanout any deposits/particulates. Any blockage in the numerous tranny passages will eventually destroy it.

Just my 2 cents.

I'm think I'm going to do the tranny and rear end on mine when I hit 50K. I think doing my 02 at 200K was the first time it was ever done (thanks previous owner!) so if I do this one at 50K it'll even em both out! The rear end is easy and cheap. Like me.
