well i have a water leak on my 03 Powerstroke 6.0. i have water in the valley but i cant see exactly where it is leaking. it only leaks if i leaf the truck sitting for more than a day or so... if i run it atleast once a day it does not leak at all.

any ideas of where it might be leaking?

 

Try looking here:

Is this hose in your truck "blue" or "Orange"?

Good place to start.

 

If it is leaking there, follow this thread:

Oil cooler to Egr cooler orange connection hose. The new one is blue and a better quality.

 

Good work,I was just digging something up for him.It is a very common leak on the early trucks that had the orange hose.

 

And here is a thread for suggestions and part numbers to buy replacement parts.
