Review on 🚗✨ Enhance Vehicle Performance with Derale 25791 Fluid Control Thermostat Kit - Silver by Daniel Shankle

Put a really cool 40k on my Sierra and it did exactly what I needed over the summer. 40+ degrees shaved when it's three digits and I pull a camper However, it excels too much in heat dissipation. Towing my boat back up the steep roads from the 110 degree dock it never went above 180 and dropped like a rock to 160 on the freeway. When it cooled down in the winter I had to turn it off completely. Entering the thermostat. In 90 degree weather, which was pretty good, I was only able to get it to 172, and if you're not in it you go right back to 168. That's exactly where I wanted my temps to be, and worst case scenario I subtract I don't expect it to ever surpass 180 and my transmission is more than fine with that. For the installation I used Dorman 800-606 transmission fittings. They have a 3/8 NPT to 3/8 quick disconnect like the rest of the transmission fittings on my truck.
