  Q: How to remove and refit the water pump on Volvo V50?

  A:

  Before moving further, be sure to listen to some warnings given. Start by draining out the cooling system. For 1.8 and 2.0 litre petrol models, pull the plastic cover on the top of the engine straight up from its mountings, remove the auxiliary drivebelt and then slacken the bolts holding the water pump pulley using a strap wrench, to hold the pulley while you loosen the bolts. It is also possible to slacken the bolts in the pulley before removing the auxiliary drivebelt. Next, remove the bolts and pull the pulley from the water pump, then undo the three bolts to remove the water pump and discard the O-ring seal. For 2.4 litre petrol ones, timing belt, retaining bolts and water pump are to be removed, and the access to these components may be limited and a little engine adjustment is required. Thoroughly remove all of the old gasket from the pump and cylinder block mating faces. For 1.6 and 2.0 litre 4-cylinder diesel engines remove the timing belt and undo the bolts (seven for 1.6 litre engine, five for 2.0 litre engine) and remove the water pump from locating dowels, recovering the gasket and O-ring seal, as applicable. Clean any residue of the old gasket off the mating faces. For 5-cylinder diesel engine, open the cooling system, remove timing belt, brake vacuum pump and lower torque rod. Insert a camshaft locking tool in the aperture revealed by the removal of the vacuum pump, then undo the four bolts to remove the upper timing belt sprocket and the three bolts holding the rear timing belt cover in place. Undo the seven bolts for the water pump and slightly move the back timing belt cover forward. Support the engine from above with an engine hoist and move the engine slightly to the right, and the water pump forward a bit. Then, move the engine back to the left and remove the water pump from the locating dowels. For refitting, a new gasket and O-ring seal where applicable, to locate the pump in position, apply a little thread-locking compound and tighten the bolts in a diagonal sequence progressively to the specified torque. Finally, refit all the components as described and replenish the cooling system.
