Looking to buy a rad hose pump and I need the inside diameter of the hose but I don't want to drain the fluid just for the measurement. Anyone know the size?

 

The hose or water pump?
Can't you just tell parts store your engine size?

 

the parts store says that they don't have the size on file, and the hose I believe

 

Should be 1.5" on both upper and lower Rad connections

You can look up a replacement rad for your year and model of 4.0l, OHV or SOHC, and it will tell you hose connection size
But in general 1.5" was what ford used on V6 engines
