The Ford 4.0L V6 SOHC engine is found in a number of models, including the Ford Ranger, Ford Sport Trac, Ford Mustang, and the Ford Explorer. It was manufactured starting in 2001<--- WRONG Started in 1997 for the Explorer
The SOHC version was introduced in 1997 in the Ford Explorer, alongside the original pushrod version

I replaced the thermostat on a 99 Explorer 4.0 SOHC and now it is leaking from the housing. It does have a new o-ring gasket Duralast/Flel-pro #35617 and the 3 bolts are tight. I don't understand why it is leaking? Any ideas or suggestions? Maybe use some RTV?
The lower housing splits apart from it's sonically welded seams. Never heard of a long term repair using RTV or two part epoxy.Before I replaced the thermostat, the housing was not leaking. Can I just use RTV to seal the housing?
See step 4 in the linked "how to" above. Looks like you broke the nipple for the bypass hose. Make sure the broken piece doesn't get into the cooling system. Be especially careful with the three lower housing alignment tabs, and o-ring seals when reinstalling.
I believe you are referring to the CKP harness, it attaches to the front of the engine, with a few of those dreadful white barbed wire guides. Definitely worth moving out of the way.
The aftermarket aluminum housing recently became available, however, it uses the newer non threaded sensors.Yes it is plastic, I believe they are all plastic. Even the OEM is plastic
