In addition to sand, there are other things that the filter is removing. SCAs, or supplimental coolant additives used in protecting against cavitation, often flake off the walls. This "precipitate" is a very abrasive particle - like a scale - floating around freely in the system unless caught by a filter.
The DIESELSITE Coolant Filter Install Kit will remove the loose particles in your cooling system and give your water pumps, radiators, water necks and radiator hoses the protection they need from these abrasive materials. Wear is virtually eliminated by the removal of undesirable elements in your system. The desireable elements, like the actual chemical used in the SCA is not removed.
Recommendations on filter changes:
Use one filter every three months for the first nine months after installation. The lack of flow into the expansion tank is an indication that your filter is plugged. Change the filter if it should plug before the 3-month interval. After the 4th filter is installed your filter should be changed once per year.
