Replace Aftertreatment DEF Dosing System Coolant Filter

NOTE: Aftertreatment DEF dosing system coolant filter location varies by application.

On some applications, a replaceable filter is in-line with the coolant supply hose to the aftertreatment DEF tank header. This filters coolant as it flows to the aftertreatment DEF tank header. See your qualified engine service provider for diagnostic and troubleshooting information.
