2013 Tahoe..Preventive vs Reactive

[Seamus]

My brother just sent me an email asking the same thing...he is at 105K...:

My detailed response:

Differential fluid is very 30-50K depending on use. Amsoil sever gear fluid only. Order online-- you need 2.5 quarts buy 3.

Transmission is 50K for sever use (Florida is considered sever due to heat) or 100K minimum. I do every 30-40K depending on towing. I use only a Wix filter from Napa auto and Valvoline full synthetic (red bottle) from Walmart---18 dollars. You need 2 gallons to do flush and filter.

At 100K change all 4 O2 sensors AC Delco only--(comes with all proper clips and mounts) Rockauto.com best place for this. It pays for it self in fuel mileage.

80-100K change spark plugs. Iridium stock replacements only. Wires too.

at 100K or when doing brakes-- check hubs and bearings.

100K change tensioners and serp belt. AC belt at same time

Oil every 4-7K Mobil 1 depending on use.(Walmart best price 25.88) Wix gold filter Napa auto parts only.

5 years 100k change antifreeze. Inspect lower hose for bulging.

Flush power steering fluid

front and rear sway bar mounts and end links bushings ( barely make 100k normally)

I know that this has been a while. However I am following your recommendation for my 13 Yukon.

When you say “ sway bar mounts” is this the part you mean?

These, whichever ones fit your sway bars where they mount to the truck.

Some good advice here, I would 100% add a PROPER injector flush and top end decarb every 30-60k- the kind where the fuel line drinks from a separate can mixed with gas and a cleaner (Wynn's, BG, GM Top end, etc). Really, it depends on how long you keep cars. If you plan on keeping it 10+ years, do everything you see here that you can. If you turn them every five years or so, just follow the owner's manual and fix things as they break. Staying ahead of it DOES help - my 1995 Suburban has 370k on the original engine...after it seized while starting at 200k. I haven't seen many LS engines will do that but if you delete the AFM/DoD and stay in front of it, you might. About to replace shocks, sway bars, rear brakes, and some fluid changes myself.
