Replacing thermostat on 2001 Crown Vic (base model)

I understand the thermostat on this model has an "O" ring seal rather than the standard gasket on the water outlet? Does this require any special sealant in place of permatex gasket sealer? Also is the OEM thermostat 190 degrees or 195? I see both temps listed as OEM......

p.s. any other tips on removing the water intake (outlet) w/o damaging it?

Re: Replacing thermostat on 2001 Crown Vic (base model)

Thanks for all the help! Yes it had an oring, sealant not required. Replacement oring (part # F2390 at Oreillys) leaked (to small) used old oring, no leaks. No traditional outlet/block (in this case plastic) gasket.....

Great you fixed it. I've taken the new O'rings and streched them to fit and installed it before they shrunk back. I've also used the old one as you did.

Where you live, either will work but maybe the 190 is better. No big deal though.

Re: Replacing thermostat on 2001 Crown Vic (base model)

thanks for the after thought, thermostat is opening/closing fine. I had R&R'd and flushed the antifreeze, hoses, cap, air filter, but didn't change the the thermostat (lesson learned). I think the durolast therm I put in is 195 deg. (autozone) and it came w/a flat therm to outlet gasket but didn't trust it as the old one was an Oring, not flat...Happy New Year ya'all!

Yep, they use an o'ring. You did right. They should know that. I've used the old ones many times. Is ypur manifold plastic in front or aluminum? My 2000 still has the plastic with 151000 miles. Hoping it hangs in there.

Happy New Year to you too!!

Re: Replacing thermostat on 2001 Crown Vic (base model)

I've had my 01 since 9/06 and now has 87,500 mi. and has the plastic bolt housing. I was careful not to over torque thanks to the website. I'm kinda amazed that my post had 63 views and no responses.......would of been nice if someone had confirmed my suspicions before I went in (it's my only vehicle and no part store for at least 30 miles).....If it helps somebody else then I'm a happy camper.
