I have a 2010 F-250 6.4L Lariat that has a small water leak at the point where the lower radiator hose connects to the lower outlet on the water pump on the drivers side of the pump. The hose appears to be attached with some sort of a snap ring and the hose is loose and leaks when shaken. How do I tighten up the hose to stop the leak? There is no coinventional screw down type of hose clamp????

 

You buy another hose. That is a quick disconnect. Your current hose is that of a single o-ring design to connect to the water pump.

Getting a updated hose will have the double o-ring design.

Just lift the wire and pull to disconnect.
