Hey guys and gals, I'm currently searching for a Water temp gauge and radiator sensor adapter attachment for my 2002 EM2 Civic.

I'm looking for something like this, but want to make sure that I find the correct size.

I'm curious which size I should get for the Sensor adapter attachment, What size would fit my upper radiator hose? Does anyone happen to know? I greatly appreciate the help.

This is mainly because I'm about to replace the radiator, and am interested to see if the new radiator will help cool things down dramatically. Because currently, I've seen some signs of overheating on the previous spark plugs.

Take care yaw

26 to 27 mm is the ID of the hose. so shoot for an adapter with about 27mm OD so you don't get leaks

 

That was pretty close to my best guess. About 26 or 28 were my two guesses. I thank you!

 

I second that
