just FYI, you can buy a dye for about $8-10 that you pour into radiator and it will expose leaks and let you trace to source. it glows a bright yellow/green and you WILL see it. oreillys and napa usually keep it.

Most of them are UV sensitive too, so if the leak is so small it's hard to see you can hit the underside of the truck with a black light and still find it.
