Paul,

Thanks for the coolant flow rationale.
Currently the Mazda pump pulls coolant from the rad and pushes it into the
driver's side water passage per the info that you stated.  The coolant comes
out of the block on the passengers' side and goes to the radiator.

Would it be possible to place a stand alone  pump inlet at the outlet of the
block on the passengers's side and push the water through the radiator then
back into the block inlet on the driver's side?  The flow would be the same.
The down side would be that the pump would see the hotest coolant.  Are
there other issues?  Thanks for any help.

You might get just steam from time to time.

If you are mounting the remote pump down low that
is the best place. If the water level is down the water input
to the pump will still work.
