Hi my question for anybody that might know about the egr acctuator on a 2012 freightliner. My question is mines is leaking coolant, do i have to buy a new one or can i have new 0 rings put in. Thx

Hey, i have a 2013 cascadia, i also have the same issue, i have to buy the whole thing not the gasket. It's all one piece and they don't sell the parts separately. Hope it answers your question. Dd15

Should be the o rings

My EGR in my 2015 Casscadia was leaking coolant and freightliner only changed rings. It a depends how badly that leak is. If it's a steady or continues leaking, replace it!
