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!

Perfect fit, works great

Listed as it is ! Good product.

Temperature switch is china junk. 1st did not turn off until cold, 2nd one sometimes comes on does not turn off.

So got system all wired 100% works great! Was a dummy for a second and thought it didn’t work but works great … don’t forget to ground the adapter!

That little allen head screw is for a ground.

Looks good and fit well. Make sure to clean the inside where they drilled for the sensor. Got two sensors but hey, prefer x tra then missing parts.

I first tried the 210 sensor and the needle went over the halfway mark so it worked perfectly but was running a little hot. I then switched to the 200 degree and it never gets above the halfway mark now. the fan runs a little longer which is no big deal. If they had a 205 degree sensor it would be perfect. Otherwise the OEM thermostat I have is a 192 degree and I have had the 185 thermostat before and the car ran a lot cooler but the 192 keeps the temperature more consistent. Also the sensor is mounted as the water is coming out of the engine so it’s not reading the radiator temp like most fans. I think it’s best to get the sensor as close to the radiator as possible which I did. This may depend on which OEM thermostat you’re using. I used the 40 mm version on the return radiator hose. No problem with leaking I did buy better hose clamps though. Just make sure the sensor threads are making contact with the metal pipe which should not be a problem even with teflon tape. Then ground the screw to a ground. I also used a relay. This sensor goes to ground when at the high temperature reading. Update sensor now won’t shut off. I may have to buy another one. Lasted a couple weeks. A few days later I plugged the sensor back in and it seems to be working again. I’ll give another update.
