I am looking at installing a Jet 180* thermostat but when I search for the part a warning comes up saying that it wont fit my engine, but I searched for it under the 5.7 Hemi info. Can anybody clear things up for me? Also, any suggestions on what dyno software to use that works best with the Predator tuner? I have the usual upgrades on my Challenger, K&N CAI, Corsa 2.5"in dual exhaust, Predator tuner running the 91 octane CAI performance tune. Thanks.

Go to NAPA, pick up part number 165, pocket half the cost of the overpriced Jet.

I agree with Mike. Or ask for Motoraid 4127 or 4128 which is also packaged under Valucraft. Those are 175 and 185 degree thermostats. They require just a bit of filing on their edges to fit nicely.

Couple of other comments. Some cars are sensitive to not getting warmer than 180 degrees and will throw a code. I run the 185 degree thermostat year around in Minnesota and not had a problem for years. The suggestion to set the LS fans higher than 190 may not yield the performance results everyone wants. Some people believe that at temps over 190 for various reasons often debated from engine temps to intake temps effected by the heat; the PCM is prone to pull precious timing, thus not allowing us to achieve optimum results and get the full advance in our timing that we set-up in the PCM with our little devil of a Predator.
