I think (but do not know) that the gasket design is the same for all of the water pump vendors (Aisin, HEPU, SKF, etc.) because the mating surface on the engine is what determines the shape and location of bolt holes for the gasket.

I put a plastic bag on the outside of the car over the roof and back left corner of the tailgate during th...
