Everyone talks about buying the kits anymore. I just can not find my old one and I need to go buy another. Does anyone know what size the tube needs to be for the 2 hoses. I am thinking like 5/16 but I am not sure. NO search did not help. Thanks

5/16"

The nipple on the coolant tube (on the motor) is about that size, the fitting on the radiator is bigger. You may have to ream out the inside of the hose to make it fit over the radiator fitting, but it'll work.
