There is a service bulletin on Freightliner trucks that have the dd13 or dd15. It is recommending removal of the coolant filter as they are clogging up. I believe it is all years but late model for sure. Check with your dealer for confirmation. You have been warned.
Yep. For me it was happenstance. Went in for some parts and was just talking to the manager and found out. By the way, that filter looked bad coming out and it wasn't even due for replacement by the Freightliner service schedule.
