Review on πŸ”₯ Painless Performance 30111 Auto Thermostatic Switch - 185 Degrees On/175 Degrees Off with Adapter by Kirk Womack

Revainrating 5 out of 5

Works great: engine cooling and air conditioning

Accidentally ordered the wrong size but finding the 1/8 NPT fan switch is a nightmare. I decided to use a larger thread in the coolant adapter, soldered the pigtail, it works fine. still easily manages two Mishimoto electric fans on my ae86. The temperature was off by a few degrees, but only one gauge was used to check, no cross calibration. In any case, the car remains nice and cool so far.

Pros
  • 1/2" NPT to 3/8" NPT adapter only
Cons
  • poorly thought out
