Year One’s Hot New Aluminum Water Pumps Keep Big Blocks Cool


Dropping a few pounds never hurts anyone significantly, especially if you can reduce pounds from your ride rather than your waistline. To help your weight reduction program, Year One has an all-new aluminum water pump housing (part no. FDR8006) for all the B/RB and Gen II Hemis. The housing is a driver-side lower hose casting that weighs in at just over 5 pounds.

Compared to the cast iron unit, the weight savings is almost 8.5 pounds. Year One’s housing has both the early- and late-style alternator location bosses cast into it, making it compatible with nearly every driver-side inlet application. In addition, the housing is cast with oversized cooling passages to maximize liquid flow. Year One offers the pump housing gaskets separately (part no. MJ1007).

Continuing with the weight reduction, for the owners of ’68-’69 engines, Year One has recently introduced the all-new aluminum water pump (part no. YQ90). Contact Year One for other engine year applications. The pump comes with a cast-iron 6-blade impeller and a 5/8-inch pilot shaft, which rotates in the factory clockwise direction.

Year One states, “The aftermarket water pump looks and functions like the original. It differs in appearance from your original pump only in the lack of an original casting number and the finish.” To complete the installation, Year One suggests using a pump gasket (part no. MJ1006).

Whether you take off a few pounds to increase track performance, enhance fuel economy, or for better cooling efficiency, Year One’s aluminum cooling system components are for you. For more information about Year One’s cooling system parts and applications or all its restoration components, check them out on the web or contact one of their knowledgeable representatives.
