How often should that be changed Jim, or at what signs should service be done?

I guess I’ve never heard of anybody ever talk about it, the iveco sure, but not the Cummins.

I’ve got one Cummins engine that’s making some weird squealing noises that our tech thinks is the egr cooler gaskets, but I myself can’t isolate it to that area.   Maybe something else like this?  It’s got about 3000 hours on it.
