That pump was located on a bracket on the front of the engine and was driven by a v-belt running off the crankshaft dampener pulley.

Not sure if your set-up is the same, but to me it would seem like the logical place to start looking.

PS...Follow the hoses from the heat exchanger to your engine.. one of them probably goes to the pump.
