Audi A4 Water Pump

The Audi A4 Water Pump is applied to maintain the temperature in the engine by pumping coolant through the block and radiator to allow the heat to dissipate before it does any damage to the engine. The Water Pump of present powerplants in Audi is driven by a belt off the crankshaft, and consists of a bearing-supported shaft on which one end carries a pulley and the other carries an impeller that forces fluid through the lower radiator hose into the water jacket and back towards the thermostat and radiator. The more recent Audi models are becoming more electric-powered pumps which rotate autonomously of engine speed and efficiency and reduce the warm-up time whereas older belt-driven type pumps are mechanically based and use a pulley, but they all share aluminum casings and tight shaft seals. Cast iron versions are now rare throughout the Audi range. The indication of a faulty Water Pump can be loud shaft noise, dripping coolant or an increasing temperature gauge reading. Since this Water Pump has a service life of approximately ten years, Audi owners are encouraged to maintain it by filling the tank with distilled or pre-filled coolant rather than mineral-rich tap water, checking under the car to determine any damp spots, allowing the engine to cool off, and replacing worn-out belts at regular intervals, which will help their A4 remain cool in all seasons.

Choose original equipment manufacturer Water Pump for great performance and strong durability. They use Audi's official craftsmanship and high-grade materials, and meet strict quality standards. Are you looking for quality Water Pump at a good price? Come to our online store. We carry a wide range of genuine parts for your Audi A4 and the prices are competitive.
