stupid thermostat

[BeatDaSHO]

I need the part number for the 180 degree thermostat from motorcraft. I go to this freakin store about 25 mins away and he looks it up and says he has it. Ok great. So i look at it and i'm like now are you sure it's the 180. He goes i am positive. I said are you definately sure. He says yes. So i get it and come back home. I look up a post from SDPatt and here it's not the freakin 180. It's the 192 or whatever. These clowns say they have no part listing for the 180. What now??

It is the Motorcraft E9DZ-8575-B or RT-1112, but you still have to specify either the 82C (179.6F)or 88C (190.4F) version and it looks like the parts guy rather than the thermostat is the one you should be calling, "stupid."

LOL I thought the t-stats were just dumb and ignorant!

well i told the guy that it was the 180 degree one and he still didn't get it right. i also called ford and the guy said that it wasn't specified at all so how do i know if i'm getting the right one??? can i just use the 192 that i bought and be ok with it?

It seems strange to me that two different units would have the same part number. That just doesn't make sense. More likely is the belief that the 82C part was discontinued. Maybe some old stock was getting sold under the new part number. I'd like to hear a more definitive answer on this. Several people have said the 82C part is discontinued and you can only get the 88C part now. Scott says you can get both. We have a conflict here. Who's right?

You can purchase a 180 thermostat at autozone it even has the ball valve to purge the system. I don't remember the part number I asked for the medium temp, it was listed as high or medium temp. but had 180 stamprd on the termostat.

I replaced my thermostat with an 82C Motorcraft part purchased at a local Ford dealer last year. If they have been discontinued since then, that is news to me. The Robert Shaw brand has a good looking thermostat in their new Generation 2 line that has a ball bearing "jiggle" valve and the rubber seal in a 180 degree thermostat for about $8. I could not find the parts cross reference to confirm it, but I am hoping that there is one for us.

well i installed the 192 degree thermostat into it tonight. Turns out, that's what i had put it originally so i was happy. The old thermostat was stuck closed. I get it all back together. Fill it up and start the car. It heats up to the M and then the thermostat opened and it moved to the L. I was like sweet. so i put more fluid in and all of a sudden the temp shoots up to the N. The thermostat opens and it goes to the O. This was the same crap it was pulling before. So i open the radiator cap and fill it up and watch it. It goes back down once the thermostat opens so i did this for about 10 times. I drove on it and came back (still heated up to the N) took the cap off, and filled it up. Same thing. I did this seriously about 20 times all together. I doubt there is that much air in there and plus i don't think it woudl heat up that much. I'm gonna try a new sending unit tomorrow and see what goes on but does anyone else have this problem. I'm stumped if it's not the sending unit.

Did you set it so the jiggles were on top? I just changed both my thermostats; the part on the box doesn't tell which thermo is inside; only whats stamped on the unit. As for filling it up, if you were still able to fill it "20 times", then there must have been that much air in the system. The easiest way to fill it is to pull the water line off the front of the throttle body, and fill till it flushes through the hose. At that point you're 95% of the way home.

Greg,

I had this behavior, but not as bad as you because I knew what to expect. It's tricky to get all the air out and if you don't do anything special, it just takes time. You will get that needle jumping hot and then dropping off because the gauge sender will get hit with air that's hotter then the coolant.

I remember the 2.5 liter camry V6 had two bleeder valves on each head for releasing the air when filling the cooling system. Removing that throttle body coolant hose is a sort of make shift bleeder valve. By now you probably have most of the air out so don't bother. But remember for next time.

Personally, I'm happy with the 88C thermostat in my MTX. The way I see it is that while the temperature differential is lower in the head now, it is higher in the radiator. This will even things out. Plus the computer controls the fan. Before, with a 82C robertshaw (non jiggle valve version my dad put ages ago), the fan would rarely come on except in really hot weather. Now my fan comes on and does some useful work every now and then. My needle goes to just below M and stays there except in stop traffic. But hey, in traffic it would go up with the old colder thermostat too.

Also, as an extra measure, I dropped my coolant concentration to 35% and am using water wetter as an SCA. Even though it's Dexcool, I'll just drain a gallon out of the radiator once a year and pop in another bottle of water wetter. No matter how much hotter that thermostat is, my cooling system is rejecting more BTU's then an 82C thermostat with a 50/50 coolant mix.

Scott, if they did discontinue that 80C part and you ever decide to try the 88C part out instead of the Robertshaw, I believe the Dexcool SCA package will allow for a 40% concentration with the same extended intervals. My containers of Havoline dexcool actually list the 40% concentration on the tables! It's been a long time since I've seen that since the 50/50 mix has been the American standard and most antifreeze takes that into consideration with regard to the corrosion inhibitor package. 40% should make up for a hotter themostat. It never gets below -7F in your neck of the woods, does it?
