Diesel Site Replacement Coolant Filters

These are the NON-CHARGED FILTER UNITS. We recommend only the non-charged units.

We no longer offer the pre-charged filters and have never recommended using them.  Pre-charged filters are designed to maintain SCAs in the coolant by timed release tablets.  This does not replace properly checking and balancing your system.

For easier maintenance of your coolant system, use RMI-25 and the non-charged coolant filters.  RMI-25 requires no balancing.
