Loosen the bolts on the water pump pulley, then remove the belt, then remove the the 4 pulley bolts on the water pump. Then remove the water pump bolts, I think there's 6 bolts, size 8mm then remove the water pump.

Not many of these cars to the euro here in spain ,best advice on this one is to ask a local mechanic how to do it and call on his services if you cannot do it or dont have the right tools .sorry for no instant fix
