Jlo2001supercrew

Have a 2001 f150 supercrew with 5.4 I have been smelling coolant for a few days finally crawled under truck appeared to be wet on passenger side underneath bottom passenger side corner of radiator. Hose? Radiator leak? How do I tell which ?

You could put some uv dye into the coolant and check that way. Other than the 'dry finger, wet finger' check; it's hard to tell unless you can see it.

My gut would say a hose; unless you've had an any type of trauma to the front end. Those wear out faster.
