New Vehicle - Service Suggestions

[yolo33]

Howdy all,

After going back and forth about Tahoe vs Suburban, I ended up purchasing a 2011 Suburban LT with 125k miles. The truck is fantastic condition inside and drives like a dream, but does have a small leak in the oil pan, which I know will need to be repaired.

While at idle the needle jumps ever so slightly so the very slight rough idle is hardly noticeable but is there. However, it's due for new plugs and wires. Am also throwing on a new serpentine belt.

Other than plugs/wires, what other maintenance suggestions do you have for this model and mileage.

Thanks SO much!

Flush everything including brakes and power steering, coolant, diff, trans, transfer case.
replace heater hoses & T's
replace all 4 02 sensors
clean the intake, throttle body, maf
throw in a few bottles of injector cleaner for the next few tank fulls (use 2 bottles per tank) or 10oz if you buy the big bottle which is much cheaper
inspect your brakes and front wheel hubs, bushings, sway bars, end links
if the battery age is unknown consider a new battery and clean up the cables with a wire brush
basic stuff to keep you running smooth.............

What @Doubeleive said. I think we can consider this thread closed......LOL

i'll even roll the dice and bet the first thing to go is the radiator due to age, unless it's been replaced already.
they like to crack on the plastic end caps

Didn't think about that. It hasn't been replaced, so certainly wouldn't hurt to inspect that. Everything else suggested I'll add to the list to get knocked out. Appreciate it.

it's just something that happens especially if it has not been driven a lot and then suddenly starts getting driven and of course it's getting warmer now, if it happens it's usually a slow leak and most likely won't leave you stranded on the side of the road
or it might last another 10 years.....lol

Sorry to revive this thread lol, however I was provided all of the maintenance records for the vehicle this afternoon. It looks like at 100,000 miles the plugs & wires were replaced as well as the throttle body was cleaned. HOWEVER, there is still a very slight rpm needle jump while at idle.

It's now at 125k so would you try and change the plugs/wires again or what direction would you suggest to figure this out? I still need to clean the MAF and install a new air filter. (Our local service center is ran by a "Gomer Pyle" kind of fella so I am avoiding going there at all costs)

I’m no mechanic but I’m pretty sure the plugs/wires should not have issues with 25k miles.
You never said what motor is in your truck.

Best to find a good mechanic (someone who knows that motor) to diagnose the rpm jump. 125k is not a lot of miles on that truck and V8 motor

Yeah that was my thought with the plugs and wires. Its the 5.3

I clean my throttle body & maf about every 3-4 months regardless of "mileage" I also intermittentley add injector cleaner every 5-6 tanks
if you wait until 100k to clean your throttle body it's gonna be nasty asf, no sense in putting off maintenance that can be done in minutes on a regular basis
I would recomend at least once every 6 months just to keep everything copasetic
usually minor idle issue's are cleared up by cleaning the intake and adding injector cleaner to each tankful for a few tanks (back to back), one dose is not going to do much
you could go a step further if you suspect there may be some other issue and monitor the fuel pressure with a gauge, harbor freight sells them for like $30, you don't need a $300 snap-on kit for something that may only get used once in a blue moon
