This is a great way to preserve your heater core from becoming clogged from loose particles in your cooling system.

This inline heater hose filter is a great device that prevents radiator and coolant system damage. It removes rust scale, gasket material and other foreign particles from the cooling system before they can build-up and clog or block radiator cooling tubes.

It is also used as a diagnostic tool for analyzing overall coolant system operation by providing a “window” into the over-all flow of coolant.

The Coolant Filter is an accessory to the cooling system, designed to be installed in one of the heater hoses of your automobile.  It is a full flow device, which traps foreign particles thus avoiding radiator repair or replacement due to clogging.
