By filtering these contaminants out of circulation, the filter reduces the risk of abrasive wear on water pumps, thermostats, and seals. It also helps maintain more consistent coolant flow, which is essential for engines experiencing large swings in operating temperature. If your engine begins showing signs of coolant-side debris, the Paccar 1843659PE offers a straightforward way to restore balanced thermal control.
