Hey folks.

This is for an '88 2.1 WBX.
This image: http://tinyurl.com/ppku2g4
shows a 0.5 mm step with a curved concave "groove" CCW from that step.
Wear becomes less deep as you look CCW from the step.

I think it is, but is this wear caused from a worn out coolant pump?
Will that amount of wear cause a significant loss of efficiency in
terms of coolant moved?

The pump I removed doesn't feel like it has any play and appears to be
a replacement part. I think it will make a good spare part though I
wonder if the seals on it will shrink.

I'll install the new coolant pump regardless. This is just a point of curiosity.

Neil.
