🌡️ JET 10171 Thermostat: Optimize Temperature Control for Ultimate Comfort! Review

Great product, good quality and does what it says. When the truck warms up, the temp gauge used to show about 209°F and now about 180°F.

I installed this on my 2002 Chevy s10 4.3L V6 along with tuning to my Nelsons Performance Tune ECM and all I can say THAT'S THAT YES The temperature rises above 180 (depending on the outside temperature). max was about 210. You need an adjustment or the thermostat won't do anything for performance.

I was a bit skeptical but this thing works. Well constructed. Generally colder. Removes the water flow restriction when the stat is normally in the closed position. The water pump (as well as the pulleys and belts) doesn't experience as much drag, so it adds some power. Rather an improvement on what you have. So between temporary tweaks and a few caveats, this works. This gives you something a standard thermostat doesn't have, and that's important. I'm thinking of trying maf.
