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.
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?
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!
I have a theory thaat the 3.7 tstat is the same or similar to the 4.7. they share a few items from thr 4.7 cooling system...so the tstat may be one. The easiest thing to do for a 3.7 owner is to go to an auto parts store and ask for a tstat for the 3.7 and the 4.7 and compare them...
Not that I know of, but like scott said you would just have to test fit one and see if it would fit as there is NOT on that specifically says "fits 3.7L"Doesnt the hypertech control that anyways?
Yeah that's what I figured, just thought I would check to see if anyone else had any luck.
Yes, the Hypertech programmer will adjust the fan settings.
I just need to find out what the optimal decrease in temp should be set to? I believe the stock T Stat is 195 degrees(but not positive), so was planning on running it at 180 - 185.
Well the idea behind it is the cooler the better, but some have said that doing that won't let the engine reach optimal operating temp and can hurt the engine.
Who knows, I'm no mechanic. Others seem to be using them with no problem
