Audi A6 Water Pump

The Audi A6 Water Pump circulates coolant through the engine and radiator to maintain safe operating temperatures. Located between the lower radiator hose route and engine block, a shaft spins in bearings in the Water Pump. A pulley at one end takes belt drive off the crankshaft. An impeller at the other end pushes coolant into the water jacket passages of the cylinder head and block. The Water Pump inside an Audi A6 is at the core of the cooling loop, and any Audi model that uses this feature relies on exact shaft sealing to avoid leaks. The liquid absorbs the heat of combustion and travels to the radiator, where that heat goes to outside air. Coolant is unable to access the bearings thanks to a seal encircling the shaft. Many examples in the Audi cooling system are aluminum die-cast. Two working styles exist: the mechanized model that generates motion via a belt and the electric version that drives the shaft through a built-in motor. The Water Pump links directly to the thermostat housing. Audi engines can overheat if circulation breaks down. When driving the A6, a constant flow of refrigerant prevents overheating. Common indications that the Water Pump requires replacement include coolant drips, grinding or whining sounds due to failing bearings, or temperature readings that are climbing, which could indicate the impeller is not moving fluid properly.

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.

A:
This procedure applies to engines where camshaft timing belt has driven the coolant pump. When taking out the pump, mark the direction of rotation of both the accessory belt and timing belt before their removal to ensure they get in the right way again. To begin with, lift the vehicle and duly support it, then unbolt the front bumper and place the lock carrier in the servicing position. Next, remove the Viscous Fan and Accessory Belt. In case of reusing the belt, marking the direction of rotation before removal is crucial. First, remove the timing belt, marking its direction of rotation if it's going to be reused. Draining the coolant and, at the front of the engine, remove the timing belt tensioner and idler pulley. Remove the timing belt guard mounting nuts and the coolant pump mounting bolts at the coolant pump, and remove the coolant pump. Prior to pumping installation, be sure to clean the gasket and sealant residue from the engine block sealing surface. The installation is the opposite of removal and uses a new gasket for the coolant pump.
