Hoping someone will know the Mopar part number for a 195 degree thermostat to fit a 99 ram v10 2500. It is definitely NOT part number 52028185AC that rockauto has listed in their v10 thermostat lineup. The thermostat I need fits down into a 3 inch metal seal. Its a very odd setup. I am not looking for aftermarket part numbers.

Try p/n 53041087AC. It looks like what you are describing. Paul TRW1982 is correct, the p/n is 53041078AC , I typed it in wrong

I got one from Napa don't know part no.

I tried the part number 53041087AC into many different sites. Its producing no results.

I tried looking for a factory T stat for my 99 V10 2500 Ram (so little support for these vehicles aftermarket or factory), everything that was supposedly factory PN#'d that I bought of Ebay ended up in the trash because it didn't fit, the best results I've had is with the Murray brand T stat set up from AutoZone/O'Riely's (been running it about 3 yrs now, no issues)....it is quite an oddball set up, if you haven't change one before there's 3 pcs required, the 6 bolt housing gasket, the T stat and the large ring seal that's pressed into the manifold under the T stat... you'll need a few slide/seal pullers to pop the factory cast brass T stat and ring seal...fun job!

op, not sure how or where you looked up the number but 53041078, 53041078ab, 53041078ac comes up all over www. says it fits dodge 2500, 3500, viper v10. also napa number for 180 deg is 613080, 190 is 613090.

OK. The last 4 numbers are 1078. I was putting in 1087. That makes a difference. No. Its anything but fun in removing and replacing a thermostat for the 99 ram v10. I did find out, after trying many different ways to remove the metal seal thats pressed into the manifold, there is an easier way. I just took a large punch and hammered one side of seal as though I was driving it down. One side of seal went down, the other side went up and I was able to grab it. I learned this after fighting with it for over 30 minutes. Thanks for your help Moparts community!!!!!

I scored a MINT V10 aluminum tstat housing last year. Had no problem finding a buyer. Wish I could have scored the front engine/timing cover, but the yard was closing up for good.

I could not believe what the aluminum thermostat covers were going for on ebay. Used. Nearly 300.00. Unreal. But if you need it, you'll pay it. Anyone know anyone who might have a v10 thermostat for sale? Mopar. No aftermarket.

My 96' Ram V10 had the black plastic housing originally. I bought a replacement cast aluminum housing back in the early 2000's. I think it was $90.00+ back then from the dealer.

So if someone is selling a whole engine for 300 bux that has the aluminum housing, I should buy it? I know parts are in short supply for these trucks but I don't want crap sitting around I might need someday.

If the tstat housing and timing cover are free of corrosion you’ll make $$ on that

Actually, I was referring to things maybe I should be buying if I find it cheap as I recently purchased a V10 truck. Otherwise, people be makin' $$ on me!
