I don't know about a 2001, but on a 99 v70 it is located in center console glove box between driver and passenger seat.
under the hood on the passenger side toward the frount of the car. With the engine off look just below the windshield washer filler neck and there will be a hex shaped cap, thats it, remove and this is your low side port. Volvo 850's dont have a high side port.
Hi, The port is between the engine and the radiator. I have included a link that shows its location. Good Luck
