Hey what's going on everyone so check it out I wanna put in a gauge system for 03 lancer for the water temp but I wanna hook up a water temperature radiator adapter. So the main question is does anyone know the size (diameter) of the upper radiator hose?

 

i just checked a few 3rd party websites and the inside diameter 1.31" or a little more than 1 1/4" (1.25")

 

Sweet thanks man

 

I should be able to fit a 1.5 water temperature adapter on it then right

 

1.5 inches is bigger than 1.31 or 1.25. More info please. Is the adapter a inside diameter fitment? To clarify, does the adapter fit inside the radiator hose or outside. I'd assume inside and it'll be a some work to fit a 1.5 inch pipe into a 1.31 hole.

 

Yeah it's a figment inside the hose lol it be tight fit

 

Good luck! Post a pic when you're done?

 

Oh hell yeah I will man thanks for the help though

 

Anytime!
