Review on Optimize Fluid Control with Derale 25792 Thermostat Kit: A Must-Have for Efficiency by Mike Bigglesworth

I was skeptical when I bought this but decided to save some money and it has worked well so far. It opens at 188 degrees Fahrenheit and starts circulating oil through my oil cooler. I recommend! I'm pretty sure Setrab buys them from Derale and calls them his own and takes a lot more. When you look at them, they look the same.
