Just picked up a 2007 Ford Explorer 4x4 with 85k miles for 4k. One owner and well maintained. I know the 4.0 motors have an issue with the plastic thermostat housings failing. Is there an aftermarket fix for this? I thought about keeping a stock replacement on hand in case it develops a leak. The swap looks very easy, almost easy enough to do in a parking lot if needed. Any experiences with this thermostat housing out there?

I owned many Ford Explorers for my work. Most were 2007 4.0 SOHC They were very reliable with several over 200,000 miles. However one broke a valve spring at 120,000 or so. One tranny went out a little over 95,000 miles (extended warranty covered repairs) and one of our white 2007's the paint just started coming off. Roof rusted, rear side panels...even the primer was shot. Never a problem like you mentioned. I hope it serves you well

I got a no-brand one from Parts Geek as a spare, but the casting could be better. Lots of pits and stuff, not sure if I will use it. The Simmons requires new sensors to work on my older model.
I would not want to replace the thermostat housing on one of these in a parking lot, but usually it's not an emergency repair. Getting hoses back on is the hard part.

Ok, that is good to hear. The reliability of these motors is good to know. I would hope the valve spring issue is just a one off and since we live in AZ, rust should not affect the body. The PO changed the tranny fluid every 30k so that should prolong the life a bit.
I will pick one of these metal housings up. It looks like a more robust design than OEM.This is considered the best by many...
