Steve, I have no experience with the mazda pump, at the time when I looked
at it, it just didnt seem a good impellor design. in hindsight I think
they're fine as I have not heard of failures. I chose Re-medy over
Electric. Next time I'd use EWP just so I could control coolant flow to
just what is needed.

Andrew
