'02 Avalanche 100,000 mile service

[Falcon_LS]

I'm helping a friend of mine with an '02 Avalanche (5.3L USDM model) that is about to hit the 100,000 mile mark. So far this is what I've got on my list, with my choice of product in brackets:

- Engine oil and filter (Fuchs Titan SuperSyn LongLife 5w30 and ACDelco PF46)
- Air filter (AC A1518C)
- Fuel filter (AC GF652)
- Cabin air filter (CF104)
- A/T filter kit and gasket (GM 24208576)
- ATF cooler line flush (GM Vehicle Care Dexron VI)
- Front/rear differential fluid (CRC Sta-Lube 80W-90)
- Transfer case fluid (GM Vehicle Care Auto-Trac II 12378396)
- Brake fluid (Prestone DOT 3)
- Power steering fluid (GM 89020661)
- Coolant flush (cannot find G-05, don't want Dexcool - Motorcraft Premium Gold?)
- PCV valve (AC CV948C)
- Spark plugs (AC 41-985)
- Thermostat (AC 12T84D)
- Radiator cap (AC 12R27)
- Radiator hoses (upper and lower)
- Oxygen sensors (AC 213-819 Pre and AC 213-819 Post)
- Fan belt (AC 6K923)

Also going to do a tire rotation. Any suggestions on the coolant? Anything you reckon is missing on the list? Thanks!

I had an '04 Avalanche.

I'm guessing you'll need a few spark plug wires as they tend to weld themselves to the plugs over time (mine did it in 45k miles) and you have to tear them to get them off. AC/Delco sells them one by one.

I'd go with a 75w-90 in the diffs (in Canada at least the fronts are spec'd for this from the factory). Otherwise your list looks pretty good/thorough.

I have an excellent series of photos of where to find the 11 zerks in the front suspension if you're interested. Feel free to PM me.

Wires yes, no distributor - one coil per cylinder.

I would use the GM 75w90 syn lubricant in the diffs if you can find it. Next would be a synthetic 75w90 from Mobil 1, Valvoline, Castrol. Not sure the Stalube will meet the GM spec. Many synthetics do not meet it but are better than dino.

I would use GM 75w90 syn lubricant for the diff if that's what its specified in the owners manual. Also, does it need the additive for the diff?

Probably not, especially if it has the G80 Eaton locker (check for the G80 code in the sticker inside the glove compartment). As I recall, the additive can mess with the locker (which has clutch-packs).
