Works great

They have a quality item and fantastic customer service that stands behind their product. The first item was defective which can happen in any product. I notified them and they gave me several options including a refund. I requested a replacement and they quickly shipped it and they even paid return shipping, AWESOME. The replacement works perfectly THANK YOU!!! Highly recommend!!

Does not turn on when installed in radiator Hose assembly , never gets hot enough. Wont get hot enough in upper radiator hoseDoes not turn on when installed in radiator Hose assembly , never gets hot enough.installed in a inline radiator hose inlet. but unit dose no get hot enough, try to go to a cooler temp sensor.OBDii reading said engine temp had to get to 215f before sensor turned on fan. probably would work if installed in head or radiator itself. I will try going to a cooler temp sensor like a 170deg.tested with heat gun and than unit did turn on fan. so it just wont get hot enough in upper radiator hose.

This review is for the switch to turn on at 200º and turn off at 185º . I don't know if I received the wrong switch or this is quality control. My car has been running bad because it adds more fuel below 185º and basically once the fan turned on it never turned off because it was continually running once it hit 200º and never got to shut off. Buy a different switch.

One wire grounding makes this switch simple and easy to activate a fan relay. Works great!

My 2020 Honda Talon x4 fan stopped working 3 weeks ago and I decided to go with larger fan with more CFMs and had everything installed except this temperature sensor which came in yesterday (quick delivery) and I installed it and grounded it properly and drove the vehicle around to better heat it up and after pulling back in and parking it with it idling I heard the relay kick in and fan came on and ran for about 2 minutes and relay kicked off as designed and fan stopped. Let this happen 4 more times and zero problems. I have no temperature guage to read the cut in cut out degrees as I have not installed my temperature Guage yet but it definitely keeps the temperature within the factory readings of only 2 bars which is factory specifications

The last switch I had (different company) lasted for over a year (maybe 2). I believe these shouldn't wear out for a decade or two so that leaves me waiting.The accuracy of the switch is very important to me as I run two and have two settings on my electric fans. These are about as close as I could expect them to be for their open and closed circuit settings.If the settings don't start having a mind of their own and they continue to live...I'll install these in all of my projects.I love to build the cars and trucks that I do...I hate to find out the weak links via upset customers.

Received a faulty thermo switch, it happens with sealed parts. Not the sellers fault! They placed a replacement in the mail, same day.

The unit looks like it's good quality - however-- the switch in not accurate. It comes on @ about 185 and doesn't open until the vehicle is off for sometime. It was supposed to close @ 195!!

Avoid this product and seller! As with other reviews, I installed temp switch and car overheated, as fan did not turn on. I removed temp switch and tested on stove with thermometer. Switch should turn on at 190 and off at 175, but did not open until 210, and not off until 140. Attempts to contact seller for exchange/refund have so far been unsuccessful.
