Motor Coach Industries - Parts Service Support - Coach Guard® Controlled Release Coolant Filter

Keep your high priced engine protected with our COACH GUARD controlled release coolant filter.

Utilizes a patented process that allows Supplemental Coolant Additives (SCAs) to be released into the coolant system only when heat and coolant flow are present. Field tests show that the supplemental additives are released at an even rate.
Competitors'' filters can "dump" all the additives at once, potentially overcharging the system and leading to additive drop-out. Or they may not release enough additives and leave the system vulnerable to cavitation erosion and corrosion. One competitor's design relies on corrosive coolant to begin the process that releases tech SCAs into the coolant system. This utilizes a magnesium plate in contact with a copper center tube that holds the SCAs. When the coolant becomes corrosive enough, the magnesium corrodes and the SCAs are exposed to considerable time and therefore the coolant system is left corrosive and unconditioned for a long time before release.
With the COACH GUARD Controlled Release Coolant Filter, all coolant is conditioned with coolant additives prior to being filtered. This ensures that no particles from the chemical mass can enter the system or plug the flow control orifice. Competitors' products have a flow pattern that routes the coolant through the filter element first.
The COACH GUARD Controlled Release Coolant Filter media is a high-capacity synthetic media designed to trap contaminants and maintain its structure through a long service interval.
