Derale 16730 Single Stage Controller Review

This single stage controller is a fantastic addition to any performance car. It helps regulate the temperature of your engine, preventing overheating and potential damage. The controller provides precise readings, and it's straightforward to install. The fan runs efficiently, even in extreme temperatures, which is perfect for automotive enthusiasts who want to push their cars to the limit. The only downside is that it's a bit pricier than other controllers in the market, but it's worth…

The description says the switch closes at 180 and opens again at 165. The switch I got wouldn't close until 200 and then reopen at 180. I expected the fan to turn on at 180 and spin down at 165. Despite the detailed description, I'm about 20 degrees off the mark.

What I received was a switch with 1/8" threads on the base and adapters. Pictured is what I wanted, a switch switch with 1/8 NPT threads. The difference between the two is Huge. The part number on the box matches this listing. So the images used for this item are clearly misleading, especially if you want something very specific. I am disappointed with what I received. I would not give my money for it wasted if accurate images were used.
