2015 DS 4369 coolant filter?

[Buly]

Just reading the engine manual, and it mentioned to change the coolant filter "if equipped" at 15K miles .
Is there a such a filter, and location, if someone knows.
Thanks

Usually not one on the ISL. If there is it should be right beside the oil filter toward the rear of the RV.
My '02 ISC had one.

Since the main purpose of this "filter" was to provide a means of adding SCA to the Coolant it was dropped with the advent of OAT or Lifetime Coolant.
It did little in the way of filtering so as a cost cutting measure (I believe) Cummins dropped it as a standard item.

When I changed over to OAT Coolant on my ISC, I installed a filter cartridge with zero SCA additives and will leave it for as long as I have this coach.

Regarding the lifetime coolant, the still ask at the manual, to check the coolant with test strips every 6 months. Just ordered some.
