Thanks for the info on the coolant flow.  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 down side would be that
the pump would see the hotest coolant.  Are there other issues?  Thanks for
any help.
