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

It is an International cast-iron pump, machined to fit the Powerstroke. You get a 205-degree thermostat, a billet housing, a silicone lower radiator hose, the plumbing, the bolts, and three Baldwin B5134 filters. The upper hose is the dual-alternator style, so it does not run through the belt. The second alternator still sits where this pump goes. That alternator has to come off, and the belt has to match.

It fits 1999–2003 Super Duty 7.3 trucks.
