If you are dealing with plastic threads or inserts in the plastic, don't over tighten them. I'd say use a 1/4" ratchet or a hand driver, and use wrist strength, not the arm. Meaning maybe 5-10lbs.ft or so. There are rubber seals there I think, which don't need a ton of torque.

BTW if you have a leak of the T housing itself, I read that the later 2002 version is possible to install, and cheaper to buy. It takes different sensors to match, there is a thread about that here somewhere. Welcome,

Well according to the Haynes manual it specifies 78 to 92 in-lbs for the 4.0L SOHC v6.

question.. surely not that much torque on a plastic thermo housing or are they ?

I'm just reading my Haynes manual.
Yeah, I hate some of these plastic parts. I don't think my intake plenum could take another un-install re-install procedure without one of the screw holes getting stripped.

Are you thinking of changing your thermostat? Or you have a leak? I think mine leaks every now and then.

And don't call me Shirley.

Alldata is calling for 10Nm or (89in. lbs)

Very good, a torque spec, that's about 7-8lbs.ft. As I said, do it with your wrist/hand, not your arm. It is easy to apply more force than is needed. That is a snug tightness for most people.
