EGR cleaning on 03 6.0L

[Guada trucking]

Ford is telling me that I have a plugged EGR cooler and oil cooler. My Excursion was running good except in this cold weather, it would smoke and hesitate so I took it in to check it out. 4,500.00 to fix it. I thought that changing the oil Mobil 1, air, and fuel filters and my diesel would keep running well forever. I guess I should have changed the EGR valve sooner.

Changing your EGR valve would not have made a difference. The oil cooler, and downstream of that, the EGR cooler, are plugging up due to coolant contamination/sediment. A good preventative measure is a coolant filter. Is your warranty up? Should be covered under the 5/100k engine warranty.

Thanks Mark for your reply, my warranty has expired, I have 110,000 miles on my diesel. Never heard of a water filter or having plugged water systems on this service. I will get my vehicle back next week.

There are a few sources for them. The below is pretty popular- nice kit that is easy to install:
