On the passenger side, under the radiator is a short rubber hose approx 10" long 1/2" to 5/8" dia with metal fittings on both ends, one end goes to something under the radiator, the other end, goes to a long metal line that goes back fore/aft. It is dripping at one of the hose crimps. I was not dressed to crawl under all the way to have a better look. Is that an oil cooler line or something else?

I had a similar problem of a small leak at the metal/rubber fitting area under the radiator.
I wrapped around a worn-out sock there and change it every 6 months. That is my creative way of fixing (or not fixing) the problem.
