Audi A6 Coolant Reservoir

The Audi A6 Coolant Reservoir helps to control engine heat by holding and releasing excess coolant to ensure that the driver has peace of mind the next time on the road. Constructed of tough reinforced plastic and supported by legendary Audi quality, this small tank can withstand continuous pressure variations; thus the cooling system in all generations of the A6 series since the initial C4 sedans is built simply to neither add nor subtract water, thereby it remains in the right amount without any air space, which can lead to corrosion or leaks. Due to the Audi reservoir being elevated in the bay, it releases the superheated fluid, which is then reabsorbed at a later stage once the temperatures are low; this simple action enhances overall efficiency and removes detrimental temperature changes to the aluminum block. The Coolant Reservoir would also be a perfect match with both front wheel drive and Quattro versions, so regardless of the car being a light four-cylinder cruiser or a strong V6 powerhouse, it will not fail cooling performance. Its durability in terms of service life is commended by many Audi drivers who state that cracks or discoloration hardly show up until extreme mileage, making it a testament to the durability of the part. The Coolant Reservoir maintains the optimum operating temperature, which in effect enables the electronic control unit to provide optimum fuel mapping that is then translated into better mileage and reduced emissions, which is a significant safety and environmental advantage to present motoring. All Audi owners celebrate the way the Coolant Reservoir fits on both petrol and hybrid models of the A6 and does not require any adjustment, which makes the regular maintenance process easier and reduces overall ownership expenses. The added heat resistance, ease of monitoring, and precise fitment in more than a single model year punch this small part nearly out of proportion to its size, just adding to the reputation of the Audi engineering department as being much more durable and intelligent in design.
