Differences in water pumps/part nos.

Posted By : Julian Saul, 22-Jul-2007, 01:03pm

My '79 !500 Spitfire is of Californian ancestry and is fitted with a water pump part : GWP205.

I noticed in the Rimmer parts catalogue, one of the few which separatley identify the US version peculiarities, that the late UK 1500 Spitfire water pumps have a different part (UKC774)/specification. The US version uses a separate electrically driven cooling fan assy..

Is anyone aware of any difference between these two items with regards to pulley size/configuration or impeller blades/diam. or are they interchangeable?
