22re Upper Radiator Hose Diameter?

I've been searching and searching and I can't find what the inner diameter of the upper radiator hose is. Any one know or have one they can measure for me?

The Dayco #71262 spare I have is 1 and 5/16 inch inside diameter, near as I can measure.

Perfect!

I'm assembling what I need to quickly install an aftermarket temp gauge and I'm going with the sandwich style in that upper radiator hose. Someday I'll relocate it near the OEM cluster temp gauge sender, but need it now.

Get a 22RTE thermostat outlet pipe

It has a temp probe fitting built into it

it measures the temp AFTER the thermo, not before, so its useful for seeing if the thermo is stuck.

In fact - its how I found out that in cold weather the thermostat "cycles" very few min or so - I can watch the temp swing up / down every time it opens...

Are you talking about the thermostat housing? Mine already has a sender in it.
