Radiators

The radiator is one of the essential cooling system parts in your Audi. A high volume of heat is generated when your engine is working and burning the air and fuel mixture in the combustion chambers. There has to be a way to cool down your engine so it doesn't overheat and become damaged. Your radiator uses coolant to help in the process. It's important to get a new one if it starts to show signs of wear and tear so more extensive damage doesn't occur to parts of your engine. You might find the temperature gauge reading high soon after starting your car if there is something wrong with the radiator. Whenever the vehicle is in the red zone, it's a sign you should at least get it looked at. It's the sign of a clogged or worn radiator. Coolant leaks might also start to occur if your radiator is wearing out. This can be caused by holes or cracks in the fins. You can check for leaking fluid underneath your vehicle. It's also important to check the coolant for any internal deposits or sludge that might build up. This can cause problems as well. Invest in an OEM replacement radiator for your Audi when the time comes.
