Advice Before Changing Coolant/Already did EGR Delete and Oil Cooler
Hello everybody, great forum. I have spent a lot of time here recently researching and trying to figure out how to best protect my 2006 6.0. I now know that I need to change coolant but am unsure how to proceed given my specific circumstance.
My truck is a 2006 6.0 with 65,000 miles on it. I bought it used in 2006 with only about 4,000 miles on it and at the time was completely unaware of the issues with the 6.0. About 10,000 miles ago I got a little wrench light on the dash so I took it to the dealer only to find out that the my EGR/Oil cooler needed to be replaced. Despite the low miles the truck was 2 months out of warranty and I was going to be stuck with a big bill. Since I had to foot the bill anyway I decided to do the EGR delete and replace the oil cooler myself with the help of a friend who is a fleet mechanic and diesel master tech.
Fast forward 10,000 miles on the new oil cooler, my temps are good. (I have an SCT monitor) Now I find out that the real culprit is the coolant and that I need to flush it out and change to the EC-1 rated coolant but I am afraid that doing so might plug up my new oil cooler.
So, finally on to my question. Is there a way to the coolant change without clogging up my new oil cooler? Since I deleted the EGR can I safely bypass the oil cooler during the flush? Should I install a coolant filter and run it for a while before changing?
Any advice for my specific situation would be greatly appreciated, thanks!
