We have been rebuilding the water pumps on the 6-cylinder DB cars for years but now we are using this new and improved unit made by JMB Services in the UK. We still carry the rebuild kits in our store for those of you who wish to do so but this complete new water pump is another option. Not only is the casting brand new but the pulley and sealing system are much improved. The impeller is an uprated design with curved vanes that circulates more water than the original straight-vane type. We usually spend about 3 hours rebuilding these pumps so when you add that to the cost of the rebuild kit this might be a good way to go. Comes with a gasket and stainless steel mounting hardware.
