Lubricating the Water Pump

The small plug which seals the lubrication point on the water pump, just behind the fan pulley, is apt to be overlooked. When carrying out the 6,000-mile service, this plug should be unscrewed and a few drops of SAE 140 gear oil should be dripped into the opening. It is important not to force in oil or grease with the grease gun and not to overlubricate the pump, as excess oil will find its way past the bearings on to the face of the special carbon sealing ring, reducing its efficiency.
