You need to get one from a second gen ram 5.9L and modify it a little. I dont remember what to modify on it though.
Keep me updated on the brand you go with and how its working for you? I reallly would like to run a 180 tstat in mine...Also have you ever ran aftermarket tstat on your 4.7? Just asking since, I have ran three to four aftermarket t-stats both 180 and 195 rating and neither one of them could keep my truck under the halfway temp mark. I ended up buying a oem tstat to keep the cooling operating back at normal temperature.
go to ANY autoparts store. tell them you want a thermostat for a 2002 5.9L. specify you want the 180 degree stant. there a couple different temps for that year (180, 195, and 210 i think) so check it to make sure it says the temp on the actual part - it should be stamped in the metal. if you will do a search for 180 thermostats you will find people who have posted pictures of the modification you have to do to your current stant. you basically just have to cut a notch like the oem stant in your truck so the rubber ring will fit tight around it. just search it though...
well guys i went to auto zone to get my 180* stat. They didn't have the stant like i wanted so i got the cheap one. Decided to change my power steering pump since it was bad. Changed it out, turned my truck on and stepped around only to see water all over the ground. I didn't even get to put my new stat in. I just got my truck out of the shop and it seemed to be running good only that i was putting water in my radiator everyday cause it would be a little low. It seemed like it was coming out of my blow back hose so i change out my cap. And here i am again. Well i went ahead and took my stock stat out and modded my 180* stat I'll see about my radiator tomorrow morning when i put it all together. Man this really sucks. . . .
ya you cant go to checkers, auto zone etc. those guys dont know wtf their talking about ..........i asked for a 180 t stat for an srt 10 and they still didnt have anything lower than 195 ...i went through jetperformance to get mine ......but ive also heard get the part no . for the 195 stock thermo tell them to read you the part . no to you and theyll read you it like ghsleh195 or something like that or its ddlgho19 and tell them you would like "dghsl180" or dkghsl18" and lol theyll look in their box and theyll have it ...a mopar tech told me to do that to get the 180 and vice versa for the 160.
no problem, another way to do this to bleed it good, put rad. cap on 1 click, not all the way, go on a 1-5 mile drive, then check the level, add some if needed then put rad cap on all the way. and you should be good.
