Got the oil cooler flushed, hoses and radiator replaced. I got a ton of debris out of the oil cooler.
You have to remove the egr cooler plate which is difficult. If you don't have one of these icon bit drivers, I recommend you get one. I use it all the time.
Oil cooler cap directly under the turbo.
I tried flushing with just the hose and got a little debris.
Then I added some compressed air at 30psi with this setup.
Bumping the air seemed to get the best result. I got 4 flushes with about this much debris using compressed air.
Most of this is iron. Some sand colored flakes.
Once it was running clean I replaced the radiator. The old one weighed about 10 lbs more than the new. Likely sediment and dirt built up.
Bulletproof diesel includes the tool for removing the trans cooler lines. I thought that was an awesome extra and wish more companies did this. Here's the tool number in care anyone needs it in the future.
Got it all buttoned up and refilled with Rotella ELC coolant.
I think I have an air bubble, it only took 5 gallons of di water and coolant. I'll drive it some more and see if the air works it's way out. Hopefully this will improve my oil/coolant temps and get me a few more years with the truck.
