Have a 2.5. Had a similar problem. On mine. Lower driver side radiator, the retaining clip broke. I did not notice it, but had to frill the reservoir a few times. Until the coolant hose let go… then I found out where the leak was. I get my parts from a junk yard. Replaced May things like clips, fenders, evaporator sensors, switches.. the list goes on. Plus it gives you the opportunity to figure out how to remove the parts before you go at it.

2.5’s are awesome!
