Does anyone know the inside diameter of a Crx Radiator Hose, I would measure mine but they are stretched at the end and i wont get a proper measurement, I want to order some Samco Hoses for a Zc Swap, If anyone knows the size samco hose i would need it would be much appreciated,

 

Measure the outlet on the radiator.

I don't know.

 

Do this. Sounds like your hose is junk.... Go get a tape measure. make the hose a circle or cut it and find out
