I’m reviewing the manual recommended intervals on my new-to-me ‘21 Powerboost and came up with a few questions. The truck is at just over 60K miles, for reference.
I see spark plugs are recommended at 60K instead of 100K due to assumed idle time from generator usage. Is changing plugs on the hybrid the same the non-hybrid 3.5L? I’ve been googling tutorials to make sure there’s no weird high voltage stuff to move out of the way but couldn’t find anything.
The manual mentions changing fuel filters every 30K, but I’ve seen on a couple places that the newer trucks don’t have serviceable fuel filters. Anyone checked and know for sure one way or the other?
Do these trucks have zerks anywhere? Again, read in a few places that they don’t actually have any to lube.
Lastly, to really open a can of worms, is there a consensus on if the 150K interval for the transmission, diffs, and transfer case is good to go or the recipe for a broken, out of warranty truck?
