Hey guys,

About to roll 170k in a few months, would like to prepare for regular maintenance.

I came across this list: https://www.driverside.com/service-...et-tahoe-2007-4994-12286-32424&mileage=170000

Is there anything that should be added? Do the timing chain tensioners on these motors ever have to be changed?

I may do a trans drain and refill but currently have no issues.

The truck was serviced regularly prior to my ownership and is in great condition and I want to try to keep it that way :)

Thanks!
