Does anyone know what size the upper radiator hose is (ID)on a '93 Escort wagon 1.9L? I looked at Oreilly's and Autozone. one said it's a 1 1/4 and the other said it's a 1 5/16.ut: My problem is that I want to install an Inline radiator hose temperature sensor adapter but the one I need is 1 1/2. I know it would be a tight fit, but does anyone know if it will fit in the escort hose? Any help would be appreciated.
