When I bought the Explorer, it was not working. When we checked it with my mechanic we were thinking it is a cylinder head gasket problem.
Confirmed it was a cylinder head gasket.
Air filter housing assembly damaged.
Center arm rest broken.
Drivers door handle broken.
Driver's seat a lot of cracks and some portions are torn.
Radiator clutch fan a lot of cracks.
Wheel alignment caster, camber & toe going to the right a little.
4x4 and low range switch not functioning.
Auto cruise system not functioning.
I bought it very cheap. As an engineer I think I could make it work & run again with an expert mechanics help.
I replaced all the above things and fabricated & adopt parts that can be done except for the last two items the 4x4 & low range switch & the auto cruise system.
It is working fine right now.
The comfort is good. The reliability still needs to be tested.
Maintenance repair engineering side without the manual you'll be lost; the engine space and design to work ergonomically not suited for home garage repairs. Tools usage good - no special tools required except for door sidings I fabricated a tool to dismantle it.
Diagnosing module hard to follow and troubleshoot need more feedback from the INTERNET and other sources to accomplish.
