Worth to buy. This product
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. Itâs really a good product. Thanks

This one has lasted longer than all of them and still has not failed or allowed my car to overheat ones so good buy ðð¾

Really lowers temperatures at high speeds
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 itâs better to have a tuner too. Highly recommend it Iâll 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.

Failed after 1,000 miles.
Junk. Failed after 1,000 miles and stuck closed.Update. They will warranty this but youâll have to pay $15.00 in shipping. Go to your local part store and spend the $21 on one with a real warranty.

Worked great for about 15,000 miles
To get the full benefits of this product you have to adjust the fan temperature to turn on at a lower temperature. But even without that ability you will still see benefits. I installed on a 2012 Jeep Grand Cherokee. Watching both oil and coolant temps before and after the thermostat showed those temperatures stay within 5 degrees of each other. Before installing 180 degree thermostat temperatures would consistently stay in the 203-213 degree range pretty much all the time. After installing the thermostat both temperatures stay 180-190 degrees while cruising but will rise a little in stop and go traffic but still stay under 200 degrees in most circumstances. My heater still works great, There is no difference in it’s function.Vehicle 2012 Jeep Grand Cherokee, 5.7 Hemi, 5W-30 Synthetic oil, 6 Speed trans, stock tires. No mods to engine or drive train other than thermostat. I hope this is helpful to anyone considering this mod.Update: the thermostat failed around 15,000 mile. For comparison my stock thermostat has about 90,000 miles on it and still functions perfectly. There is a lifetime warranty but I’m not sure I would want to put another one in even if it was free and risk blowing my engine. Sucks because it was an awesome mod when it worked.
