Hi Expy Forums,
I'm looking at used 2015-2017 Expedition ELs and was hoping for some advice. I'm coming from a 2016 Honda Pilot looking for a much more capable tow vehicle.
I see plenty in the 100k mile range and wanted to sanity check my inspection plan.
1. ATF fluid. Probably hasn't ever been changed at 100k. I'm expecting it to be burned pretty bad if the vehicle has been towing, but is that true with the HD tow package and ATF cooler equipped?
2. Spark plugs. Probably originals at 100k and from what I read the coil boots frequently break off when trying to remove them. Any concerns here other than swapping in new plugs? Are new coils necessary at this mileage?
3. Carbon buildup. Assuming no catch can, I figure the carbon buildup on the valves could be pretty bad by 100k, especially if the oil has been neglected. Is there any easy way to evaluate this without a borescope?
Any other suggestions? I know from the Used Expy thread to check for underbody rust, window motors, and give the 4wd system a good workout.
