Volvo sells a coupler to drive the seawater pump, but that wouldn't work since this is a car engine. Iwould have to buy about 200.00 worth of parts to change the sprocket over, so I welded a piece of flat stock steel to the head of the bolt that holds the sprocket on. That worked very well, and cost me NOTHING!!!!! HAHAHA!!
Someone told me once that desperation creates a vision.
