Here it is middle of January and I have to change the themostat on my 99 Explorer. Garage filled up with crap, so it's of no help.
I changed the T-stat about 15 months ago, it didn't help my low heat output in the cabin, nor change the low water temperature gauge reading. Because its a cheap fix, I'm going to change it again, hopefully this morning.
It's -14C outside and I'm planning to warm up the truck, then shut it down and put a ceramic heater in the forward part of the engine. I have some 6 mil vapour barrier and 1 inch sheets of rigid insulation with which to build a small "tent". We'll see how that goes...

By the way, I assume there is no need for RTV sealant, as I bought the O ring gasket? Rookie question I know, its been awhile...

Good news! Repair occurred yesterday as scheduled. Built a little tent around the engine compartment first. Set up took about an hour, and the actual replacement of the Tstat took about an hour. Didn't remove any other parts, just used a swivel-head attachment and a small extension for the ratchet.
The actual working conditions were quite pleasant, with a trouble light and radio helping. The small ceramic heater was at the limit of its capability, but did keep my fingers warm. Outside air temperature reached -7C (+20F).
Once repair complete and RTV sealant allowed to set, a test drive showed immediate results. Loads of heat. I now think that I installed the previous thermostat with the air valve not at the top, hence little or no water circulation (Yikes!) for the past year, and a low gauge reading, and little heat in the cabin. Remember...slow...down...

96 XLT running cold.
I just did that repair yesterday.
I used the Ford factory T.stat and a factory sender.
I removed the T.stat and did the boiling water on the stove trick.
The old unit DID open up sooner than the new one.
I also replaced the sender but all I really needed was the T. stat.
I have replaced it about 20K before. The German units seem to fail quickly.
It fixed my problem. The needle is just below the "waterline" on the guage.
If I have the problem again I might try a different manufacturer of Thermostat.

av8r4aa, i just got your handle. Airboos, MD80something or Boeing? I am in the sim tomorrow doing my cap'n upgrade on the 73NG. Cheers, and BTW, my temperature gauge is showing well into the normal temperature range
