Your best bet is to get the part number of a water pump with a metal impeller.
(SP motersport has it)
Find out what it is and order it somewhere in Canada. Do not buy the ford
replacement pump because it comes with a plastic impeller. Unless it's to
late, get the pump and install it your self. When my water pump went on me,
the dealer wanted 285 (US) on top the the inspection fee. My buddy did it in
one hour and it only cot me the price of the new pump and case of beer.
