Automotive Engine Radiator in-Line Hose Fitting Adapter Water Temperature Thermostat Sensor Electric Fan Switch Kit (38mm, 180'F On - 165'F Off)

Adapter is great quality. Only issue is have is the sensor seems to have an intermittent connection issue. The blade connector coming through the black resin is loose and slightly moves causing two issues, a coolant leak and the fans to kick on and off. **Edited rating. The seller quickly resolved my issue and sent out a replacement temp sensor to fix my issue. Thanks again!

Functional. 10 out of 10.

Cheesey China clamps though. I Bought One size over so ID doesn't restrict flow and lip actually seals in ID front of the clamp. SAE 1 3/4 Hose stretches over fitting 46mm Lip and Clamps 1 13/16 "NECK" easily. Actual Lip is JUST barley over1 7/8 in. > Hose is 1 3/4 < Note they do state " Fittings are sized by the outside diameter raised lip edge. I bought This for bottom Radiator hose for Mopar " BIG BLOCK" 383 in 69 Barracuda "Electric fan" conversion.

I gave this item4 star ⭐️ Due to the fact that is really hard to find a temperature sensor switch that fits this fine 10mm thread I bought the fitting without the sensor to save money ( you can get it with the sensor ) but it was imposible to get a sensor switch on any auto parts ended up buying the sensor here (Amazon )only to find out that the sensor switch turns on at 180F• but won’t turn off up until is really cold . Not recommended .

Don't forget to ground the thermostat hosing for the switch to properly function... too me a hour to figure out thats what the bolt is for lol.

El envío fue relativamente rápido y llegó en buen estado, funcional y económico.

Ok so it definitely solved my problem of not having a place to put my sending unit on my engine. The problem I realized is that it’s not grounded as it would be if I screwed it in the block of the engine. I added a wire around the base and grounded it to fender. Now it works perfect. It’s a great idea but needs redesigned to allow for a ground wire.

I prefer that this thing just worked, especially with a name like "American Volt Automotive." Unfortunately, this is the second one that did not work. After cutting an inch out of the radiator hose on my 1969 Saab 96 V4, a hose that is hard to find and expensive when you do, this second electric fan sensor has failed. The first one triggered the fan, as it should, but then stuck in the "on" position. The replacement that was sent did not come on, causing the engine to overheat. The attached images show my testing of the sensor. Connecting a 12v power source and a 12v LED light, simply touching or shaking the housing/sensor, caused the LED to illuminate, as shown in the video. You can see in the static images that an infrared temperature sensor is used to show the fan sensor temperature. (73.5 degrees Fahrenheit) the sensor is triggered, and the LED is illuminated. I'm keeping the second housing as it is a well-made unit, but the sensor seems absolute junk for such a critical device.
