I just had a 180 degree thermostat installed and the temp is running around 195 while driving and around 220 when sitting in traffic. I thought it would be running a little cooler with the change. Is this normal or does anybody have any suggestions? Thanks!

J.D.

Sorry, can't answer your question, but I have one for you. What brand did you get and where did you get it?

Thanks

Research the red and blue forum. You changed the thermostat, but the fan will still not turn on until a preset temperature as designated by the factory. You can bypass this by running the A/C continously, or look at InfernoSRT's comments and schematics on how to bypass the fan so that you can manually turn on the fan with a switch (blue site). The commercial alternative to the fan switch bypass is GSM's fan/traction control kit for the Jeep

SRT8 engs strongly recommend not changing the thermostat.

I can't think of many if any applications that didn't benefit (performance wise) from a cooler T-stat. I've been doing quite a bit of reading on these forums reg. a stat swap, including what the SRT engineers have said, but I have yet to see a reason to back their claim.
For now it's a backshelf mod, but I'd love to see some real tech on this (among other things) sometime soon.

I'm sorry, but I can't imagine why an eng. would ever say an aftermarket mod was good....they would then be on the hook for any associated liability...take their advice with a grain of salt. I bet if they had their own jeep it would be modded to the gills.:eek:

You can see my temps with the factory and a 195 here:

Lower thermostats and performance improvements (http://www.***********/forums/showthread.php?t=3010)

I would never go back to the 203. Now, I am just trying to decide if I should go to the 180 like you did. Winter is coming here and this won't be an issue until next summer.

I'm sorry, but until you have documented HP gains, your thermostat is just a superfluous accessory. Stanko has done numerous dyno test with the 180* stat, CAI, and Corsa exhaust. The 180* stat provided a minute HP gain with the CAI, and a minute HP loss with the Corsa exhaust. Go to the blue site and read for yourself...

I will believe SRT and Stanko over conjecture every time.

Where does one buy a stant 180 T-stat for a JCG SRT8?

Thanks

GotStroke, I could not find one here in Minnesota, although I did not look that hard. The local Walmart had Stant thermostats, but not one to fit.

I got mine at the Advance Auto Parts in Naples, FL. The part # for the 195 is 14429.

If anyone knows the part # for the Stant 180, let us know.

Correct on Stant 195...#14429 balanced sleeve for a Ram diesel..Believe Napa number is 532090

I am also pretty sure on the 180 that Napa is 532080..and Stant # is 45478. I would call Napa or Advance first to double check though.

Hope this helps...

This is the general.......and stanko said you are correct. The Stant is a balance sleeved thermo for a 2005 Ram truck. This design (balanced sleeve) helps in preventing large temperature fluctuations. The engine will run about 200 on the highway and 210 in stop and go.

The 180 has a real small orifice.....the stock 203 is large and the Stant is pretty close in size for flow capacity to the stock thermo.

:D

Just curious on why you changed your t-stat to a 180. I am running one in mine but it is recommended with the supercharger.

i have the stant super stat 14429. I got it for 32 bucks from pep boys. No probs with it

Yep...Sarge gave me the info. on which stat to get.

i have a 180 stat and a e-fan with a radiator mix from Royal Purple and I might be running around 170

I'm pretty sure everyone is referring to the SRT8 Jeep platform. There are going to be differences when comparing your Ram.

By the way, a noob question: Can someone please PM me info on the "blue site" ou keep referring to? I think I know which site it is, but trying to get all the info I can on the Jeep SRT8 before I sell my CTS-V for one.

is there any larger Radiators for our jeeps?
does anyone of you knows where can i find one?

He is running the 6.1L Hemi in his ram... I would think it would be relatively the same for his and our jeep.

why?:cool:

They dont want to see you turn your 6.1 into a 2.7 ;)

Mainly because the tight tolerances of most new engines require the higher operating temps and is the best choice for day to day driving. A low temp thermostat is mainly a benefit on hot track days.

I'm not sure where you got that from? Cast/hypereuctectic pistons don't expand like forged/aftermarket slugs. Even so, built/forged motors also run better with a lower T-stat.
The only reason I can see not to change so far is due to our ****ty speed density based engine management. Once a tuning solution becomes available it should put this discussion to rest permanently.

Engs commented on this at the Nats. Negative Response! Trans oil temp raises the coolant temps. (mine goes over 235* racing) SRT TE wouldn't allow power brake strats on the Drag Strip Driving portion! Why? Heat! Once the thermostat is open, what is left? (Cooling System) Fan mod, larger radiator, more tranny cooling, all would lower operating coolant temps. MO Experienced on this subject after dealing with it in the past on another vehicle, not my JGC. HTH Gene

Maybe this has been asked before, but shouldn't a good tuner allow you to change the fan temperature settings? This in combination with a lower temp thermostat would obviate the need for the GSM (or any other) fan mod requiring the wiring harness to be cut into. Correct? :confused:

When the tuners become available, you will probably be able to tweak the "on" temp of the fans. However, the computer programming will also need to be adjusted to accept the lower temp(from a lower temp thermostat) as "normal" so that it doesn't throw a code. Usually the particular cell that handles temp will need to have the value changed that it looks for under certain conditions. There are probably several cells that will need to be "convinced" that it's OK to have temps in the 180* range.

Guys ... Hello ... Can some1 give me a feedback on my Q.

I would contact several radiator companies to see if they would custom build one? Maybe a group buy? Let us know. Gene

I've read somewhere recently that the radiator has more than enough reserve. Get the GSM fan mod instead, or mod the fan wiring per Inferno SRT8's thread on the "blue" site, and keep your temps down. Sarge has clearly shown on back to back dyno runs that the Jeep runs better with a cooler thermostat, though the biggest gain was from 203 to 195, and not so much from 195 to 180. Given that one person had a CEL with the 180 degree thermostat in cooler air temps, I'd say go with the 195 stat.

A slightly cooler thermostat along with the fan mod will effectively incease your radiator cooling "reserve", given that the radiator (as well as the transmission fluid) is kept at a cooler baseline temp before any "strenous" driving is initiated.

One last comment. I pulled a boat and trailer with the "beast" for 1200 miles round-trip in 90+ degree air temps this summer. The temp guage was rock solid stable. Never did the temp rise above the baseline when the radiatior fan was running (I used the A/C at that time to keep the fan running continuosly)

A bigger/better radiator is this vehicle's current state of tune is probably a waste of money. Who knows with a supercharger (ask GSM Motorsports) or turbo (ask John Hennessey) installed. Just one person's experience over the past 9 months.

Thats normal unless you have a fan mod or the B&G flash, With the B&G flash it turns on the fan for cooler coolant temps, in traffic it does not go up more then 207 now, on the highway 190-195.

yes cooler is better, i work at a performence shop and yes it works, it helps w/pre detonation, less heat and kicks the fan on a lot more,180*is better then 195* depending on your location!!!a++++++ to the 180 users

I like my 170* as long as the ambient temp is above 60* no codes. It IS better at the drags so at least change it before taking to the drags.

Bill, I had the 170 stat but took it out after I got a cel. The ambient temps were 45 to 55. I have the 180 now w/no cel at all. However, for the record, I noticed a significant temp change w/the 170. The temp indicator when cruising stayed full left-below 185. I am considering going back w/the 170. I have the B&G2 now. My best time prior to the B&G2 was 13.16 w/ambient temps of 35-40 w/170, Volant, & Corsa-45min cool down.

With ambient temps of 57-62, B&G2, 180 stat, Volant, &Stock Exhaust-60min cool down, I ran 13.03. I do not have the fan mod. I do have the GSM ESP Fan Mod but never install due to warranty concerns.

Just thought I would share this info. The lower stats do work and is a common hp/tq builder for almost every performance vehicle on the planet.

I would go in person to Autozone and ask for that thermostat. And do not let them try to pull it up by your vehicle description because it won't come up. Just tell them to get that part number.

hellow everyone, im new here, just got my GC SRT a month ago. i live in the Puerto Rico and outside temps here are about 88 to 95 dreg, so im going with the mod. i went to autozone and didnt find it (just with the description of vehicle).

question: is the stat the same for the 5.7 engine?

thanks

Tell them you want a MotoRad/Valucraft 383-170 (tell them to look it up by the part number).

I have the JET 180 thermostat and has worked fine, but the other day it was kind of cool out and on my way to work I had a CEL come on. I do have a dashhawk with cleared the CEL but i don't want to have to deal with this all winter. I live in Maryland and It can get cold. Has any one with the 180 taken it through winter and if so did the jeep push out enough heat to keep you warm?

Just hang on to your OEM thermostat. It only takes 5 minutes to swap them out....

The only reason I can think of for the SRT engineers to recommend staying with the stock thermostat is for emissions purposes. The hotter the cat, the better the emissions.... and the emissions system is built around many things...engine temperature being one of them.

Hello all,

What is the level of difficulty in swapping out the OEM stat to the Jet 180 stat? Also, on top of the CAI and exhaust sys upgrade is it advisable to add on the stage 2 Jet PCM? Anyone, have this done? GOOD or BAD? Thank you for your time.

Best regards,

Treb (the newby)

Difficulty level is .001 outta 10.000 Good luck.
