MishimotoMMTS-JED-06L Racing Thermostat, Compatible with Dodge Charger & Challenger Hemi, 2006-2019

Exactly fits to the car. Was as described. Heat level was less than before the engine temperature. Not rising same as before to higher levels. The temperature stays long time between 82 - 85. Celsius. Before it rises a little a little bit but still within reasonable level. I recommend. It’s really a good product. Thanks

Excellent product, met all my expectations, keeps my vehicle's engine temperature lower than the original thermostat.

It works perfectly with my cooling system and tune on the truck, never see temps above 180 degrees on my coolant, even in traffic and in the city. It does have a coolant thermostat below threshold code, but I stuck a sticker over the check engine light my tuner runs diagnostics, and accurate readings on everything.

Works as intended, my ‘18 Durango RT now runs cooler, no need for a tune, but I’m sure if you are tuned it will benefit from it.Took me like 10 mins to swap them out, super easy!Update 8/20/24 - -Do not buy this thermostat, almost $60 dollars and failed after a year, got so bad it almost caused my 2018 Durango to start having major problems because of it…Go to O’Reilly and buy yourself a 180* thermostat for $22 and works way way better!

Loving this product so far had it for now 2 days and has been keeping my temps down I went about 70-80 miles an hour and the highest it went up was 188 then after it dropped back down to 185-181. Also it’s better to have a tuner too. Highly recommend it I’ll be writing another review later to see how it does. Also test it in boiling water to make sure it opens up before installing. I tested it in boiling water and it opened up about 179 which says 82c. November 12 2024, So far it doing good if you have a tuner tune this to 175 for low and 185 for high. When your going high speeds it will drop and should going above 185 maybe 188 at the most. So far nothing working great. If this fails I plan on going back to 203 thermostat just to be safe.

This product effectively fulfills its purpose by efficiently cooling your engine. However, it has the potential to trigger error codes in your car due to the prolonged time it takes for your car to heat up. Fortunately, if you possess an OBD device, clearing and eventually resolving these error codes is a simple task. I have personally observed that my Chrysler 300 5.7L Hemi engine maintains a temperature range of approximately 180-195 degrees Fahrenheit when I push it to its limits.

I installed it last night. Took it for a 35 min drive from my job to home and it stay at 185F. I was sees it like low 200F but this time it surprise me. I was so surprise since it’s my first 180 thermostat.

Fixed the overheating on my 2015 RT Durango even when it’s 100 degrees out
