Review: Sensor had slight issue, but seller solved my problem. - 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.

### ⭐⭐⭐⭐⭐ Is as described - Made of Aluminum - I think it will do - what I got it to do -
*by A***2 on May 6, 2023*

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.
