  Q: How is the water pump attached to the cylinder block and what considerations are there for installation on Volvo 245?

  A:

  The water pump is bolted to the cylinder block through screws, thus having a gasket despite not having a water outlet from the pump into the block. A sealing ring is located in the groove at the top of the pump that will be compressed by the Cylinder Head when the pump is installed. Fitting the water pump with the head removed is easier than with the head in for pushing the pump against the head and making sure the ring is in the correct position while inserting the bolts. This procedure is required if the pump has been removed from its position while the head is left in place.

  Q: What should be done if the water pump starts to leak, shows excessive movement of the shaft, or is noisy during operation on Volvo 245?

  A:

  If the water pump starts to leak, shows signs of excessive movement of the shaft, or is noisy during operation, it should be renewed. Begin by draining the cooling system, then remove the two screws securing the fan shroud and push the shroud back over the fan. Next, take out the fan center bolt, remove the fan and shroud, slacken the tensioner bolt, and take off the belts from the alternator. Remove the fan hub retaining bolts, the fan spacer, and pulley. For 821A and 821E engines, take off the timing gear cover, disconnect the radiator hose and the return water pipe, then remove the bolts securing the pump and take out the pump. Clean the residue of the old gasket on the cylinder block mating surface and the rubber ring contact surface on the cylinder head. Fit a new rubber sealing ring on the new pump, ensuring the correct ring is used, as varying heights of rings are available for different thicknesses of cylinder head gaskets. Place a new gasket against the cylinder block, using a smear of grease to hold it in position, then press the pump upwards against the cylinder head and fit the retaining bolts. Install a new rubber ring on the water return pipe, attach the pipe and the retaining bolts, and connect the lower radiator hose. For 821A and 821E engines, fit the timing gear casing, then fit the fan pulley, tension the belts, position the fan shroud, and fit the fan. Finally, secure the fan shroud retaining screws and fill the system.
