You didn't tell me fluid would come gushing out when I removed that bro. You need to add some details there
Hoses: Welded on, couldn't remove.
Wire clip: Impossible to figure out as usual, left on.
Forced to try and scrape at awkward angle with everthing still attached.
Wiped as best as possible with microfiber, and reasembled. Tightened to the point of stripping.
Started engine, leaked fluid through gasket everywhere, ran all over driveway. Nice.
I'll try again tomorrow. Of course, if it doesn't rain, which it will.

Yea, I didnt use a torque wrench on this. You need a torque wrench and the specs in order to torque it properly. I just tighten it to what I think is good from my experience. It helps if you know if the bolt is steel or aluminum, and if the threads are steel or aluminum. Also, smaller bolts typically dont get torqued as hard. Does this answer your question?

Make sure you boil the new thermostat on the stove. This is to make sure it opens at 195F. Use a candy thermometer to check the temp. You'd be surprised at how many cheapo thermostats don't open at the correct temp. Use a coat hanger to suspend the thermostat in the water, don't let it touch the pan to get a correct temp reading.

It helps if you loosen the serpentine belt which is in front of the thermostat housing. The belt is a real problem when changing the thermostat although it can be changed if you have strong nimble fingers. Chris has a great video on changing the belt as well as this one on changing the thermostat.

Hey man how do you know if you've torqued it to factor specifications? It's easy to tighten up some bolts but are you just supposed to assume once they can't be tightened anymore it's good? Torquing to factor specs sounds very technical, sounds different than just tightening the bolts.

Thank you that is exactly what I need to do right now on my way to Autozone because it's going to snow in a bit and its Cold. Put 2 gallons of Prestone antifreeze in my Jeep and it blows Colds so installing a new thermostat.

Great explanation! Short and sweet and hopefully everything I need to fix my p1281 engine light code. (The engine is staying cold too long - check your thermostat)
Thanks!

Thanks Chris Fix, once again you've helped me do the job myself. Mine is a CJ5 and this video was still relevant considering Jeeps haven't changed much over the years.

Yes. I even changed the waterpump without draining the coolant. You will lose some coolant in the process but not everything. Enough that you could just add water!
