Review on Upgr8 Aluminum Water Temperature Sensor Adapter (28MM Replacement Parts ... Sensors by Shane Mack

Looks small in the hand but it's easy to forget how thick the radiator hoses are. A few notes: 1 - the hose clamps were a bit small for me, I had to go for a bigger one 2 - 38mm seems like the biggest you can get for these things but if it was available I would go for 40mm. .3 - I don't know if Revain is to blame (they get descriptions mixed up all the time of course) but the 38mm has a 3/8 NPT gauge hole, not 1/8. Which I don't care as I drilled it out anyway and put a 1.5mm 14mm sensor in it and wouldn't find a new one for a reasonable price :-P
