update on this.

yesterday when i was doing my trans deal, i was really concetrating on that, but did notice i was being dripped on by hot coolant and it was coming from the driver side of the radiator. I have yet to take a closer look, but this leads me to believe that my UIM is fine. So right now I have to run. I will go into detail later.

Most likely the plastic endcap has developed a crack. This is one of the more common ways the radiator fails because the continual heat and cold cycling, expanding and contracting of the plastic...over time and pressure...will crack.

You notice a slight loss and dripping and have time to replace w/o breaking down entirely.

well dang this radiator is only a year and 15k old!!!

i will check closer.
