I have a '05 Ex 6.0 with 108K miles that seems to be leaking coolant on to the passenger side cross member. Everything on top seems dry. No white smoke on start up, clean coolant (no oil), and a 8 degree delta. The last thing done to the Ex was changing the alternator last week. Any help?

 

Moved to the 6.0L Power Stroke Diesel forum.

 

It maybe the EGR cooler hose , runs from the oil cooler to egr cooler . Look down in front of turbo and behind oil filter you will see a small orange or blue hose if its leaking you will see it dripping down to the engine valley. Or could be heater hose valve they leak sometimes.

 

egr cooler hose or heater controll valve.

 

I won't be able to check it out until Tuesday, I will post up when I find it. Could that hose leak static or am I seeing the after effects of it leaking after its been running?

Thanks for the replies,

 

either is possible.

 

Update: Unable to find the leak, had the shop look and couldn't find the leak. But this morning I looked and no puddle, started her to warm up for about 7 minutes came back out and there was a puddle. About 14" circle. The shop said it's gota get worse before they will be able to find it. Any ideas what to do next?
