Why do I want to overhaul the pump?
It's not a frequent or common job but eventually the bearings in the IC pump wear and the pump will become noisy.
What parts do I need and where do I get them from?

The How to...
Working at a leisurely pace and taking pictures, the job took about 45 minutes...
Anything else I should know?
Removal of the 205 IC pump is a git! I found I had to remove the lower splash guards and radiator overflow bottle so that the 2 pump securing bracket bolts can be undone and the pump with mounting plate can be pulled free. The pump cannot be withdrawn from the mounting clamp as the wire loom is wrapped around and through the securing bracket and clamp.
