Thanks amc, i did read about that in one of the ford manuals. The mazda cooler looks a bit different than the ford cooler, but is probably similar internally. The mazda manual says to flush the cooler so I flushed it backwards and forward with mineral spirits and compressed air and the flow was normal. I will research the mazda cooler more and price out a replacement.

Thanks again for all of your help!
