The cooling system is one of the most critical operating systems in a modern automobile. If it fails, the car will breakdown and this can result in extensive engine damage. This bulletin will provide you with the recommended steps for installing a new water pump on the below listed 1.1 and 1.4 petrol engines applications, minimising the risk of early failure.

Always install the belt, tensioner, and the water pump, as a complete kit.Toonlyreplacethetimingsystem and not the pump is false economy, and will only lead to further repairs due to damage caused by the bearing, and or seal failure of the water pump!
