Audi Coolant Tank |
Have you ever heard about an Audi vehicle having an engine overheating problem? Not frequently, right? That's because such problems rarely happen to luxury vehicles like Audis. For one, these vehicles are all equipped with high performance engines that would not easily yield to overheating. Then, all Audi vehicles are equipped with high quality engine cooling system that can keep the Audi engine working at the proper operating temperature at all times.
The cooling system of your Audi is composed of many high quality parts. One is the Audi radiator, which is the primary component responsible for dispensing the heat that the coolant absorbed from the engine. Another is the heater core which serves as a secondary, albeit smaller, radiator. Then there are the radiator hoses and the pressure cap, all functioning to aid cool the engine in one way or another. And lastly, there's the Audi coolant tank.
The Audi coolant tank is a semi-transparent device used as temporary storage for the coolant. But why use a storage device for the coolant when it was meant to flow continuously through the various parts of the engine cooling system? Coolants, because of their chemical composition, have a natural tendency to expand with heat. And because heat is the very thing that they are supposed to absorb, the coolant inside the radiator would normally expand as the engine heats up, causing it to overflow through the overflow tube into the coolant tank. The excess coolant would then be stored temporarily inside the coolant tank until such time that the engine again cools down and the radiator takes the coolant back. This is the reason why coolant tanks are also often called expansion tanks, overflow tanks or coolant recovery tanks.
Aside from serving as temporary storage for the coolant, the Audi coolant tank also serves a couple of other functions. Audi coolant tanks usually have two level markings on its surface, with one mark indicating the safe coolant level when the engine is hot and another when the engine is cold. With these markings, checking for coolant levels becomes easier and safer. The caps of modern coolant tanks would also serve as the entry point for the system's coolant tank, allowing you to replace the coolant safely.
Now, engine overheating may not be a problem that you'll have to worry about each time you drive your Audi. But the parts of your Audi's cooling system would eventually grow old and deteriorate. Also, a sharp object may puncture your Audi's coolant tank by accident. In such cases, you'll surely need replacement cooling system parts. And in such cases, always remember that you can count on Parts Train.
