Bosch has launched an upgraded water pump program that features greater application coverage and heat-tempered bearings for most applications. It’s described in the company’s new 2007 catalog (#221144), which includes 66 new part numbers and supercedes the 2004 version.

This comprehensive 208-page catalog covers applications for medium-duty trucks as well as vans and cars. It also includes technical information, installation instructions, a troubleshooting guide, a buyer’s guide, competitive cross reference, and casting number reference.

The new program includes: 100% new water pumps with a specially treated heat-tempered bearing for most applications for greater strength and flexibility to resist shearing; more hardware and studs with each pump for easier installation; gaskets and studs wrapped and affixed to the inside top of the box to protect the gasket from getting damaged or tearing; and bubble wrapping for protection.
