Re: Volvo Engine Water Pump
Those engines have closed cooling systems, ie they use a heat exchanger and anti-freeze coolant. When I replaced mine, I just bought a new automotive one, cost about $75 if I remember correctly. Had to do a slight mod to make the plug at the back fit tight, but it worked out great. So go to your local autoparts store and get a new automotive one.
Have a great day
