Smile 180 Thermostat for 3.7L V6

Im new to this forum and have researched in earlier threads about this. I recently purchased a JET performance module and it has increases mpg and throttle response greatly! They recomend using a 180 degree thermostat. Any ideas on where to find one? I have seen on other forums that people have found them for the 3.7L.

Any help would be great!

Re: 180 Thermostat for 3.7L V6

You do realize that running a colder temperature with increase engine wear, oil sludging, and fuel consumption if the ECU is not reprogrammed to not run rich while waiting for it to reach operation temperature?

Re: 180 Thermostat for 3.7L V6

Well, I've heard mixed ideas. Jet recomends using one with the chip. And theoretically, would cooler engine run better?

Re: 180 Thermostat for 3.7L V6

Re: 180 Thermostat for 3.7L V6

i dont believe they make a 180tstat for the 3.7, i know in the past we've searched and searched but could not find one...

there are a few companies that do tunes for the 3.7 but you have to get a spare pcm and tune and it is super $$$

Re: 180 Thermostat for 3.7L V6

JET makes a chip for all dodge/chrysler/jeep vehicles. It go in between your ecu plug and your ecu. helps a lot with low end torque and about +1 mpg.

I'll try and find that poster of who had a 180 deg thermo. and try to upload a pic of the one i have now

Re: 180 Thermostat for 3.7L V6

I can't seem to find the original post where someone posted about their mods to their own 3.7L and listed a 180 thermo. But It was on JG so lets hope they see this!

Re: 180 Thermostat for 3.7L V6

It could have been an older model though. I know they make a 180 for the 4.0
