The DieselSite WPCF-H is a water pump and coolant filter for a 1999–2003 7.3 Powerstroke, with the silicone lower radiator hose. The kit with the billet thermostat housing is WPCF-C. The pump without the filter is WP73.

It is an International cast-iron pump, machined to fit the Powerstroke. You get an International thermostat, a silicone lower radiator hose, the plumbing, the bolts, and three Baldwin B5134 filters. The filter catches SCA scale and sand before they eat the new pump. A truck with dual alternators has the second alternator in the way. That alternator has to come off, and the belt has to match.

It fits 1999–2003 Super Duty 7.3 trucks.
