Audi A4 Radiator Hose

The Audi A4 Radiator Hose maintains engine temperature within the optimum range as it effectively transports coolant between the radiator and the engine block, ensuring the engine does not overheat during city crawls or high-speed driving. This Radiator Hose is designed to withstand extreme heat and constant vibration; thus, it is crafted with a multi-layered synthetic rubber compound that is reinforced with fabric, as required by Audi to ensure that the hose works well even under extreme pressure. With each small vibration of the engine, its long bend keeps it in place, preventing cracks before they form and sealing the cooling circuit against hazardous leaks. Not only is compatibility extended to sedans and wagons in the B6 through B9 series, but a single reliable part can be applied in gasoline and diesel versions of the A4 without making any changes, maintaining that smooth ride that the driver is accustomed to when using the larger Audi family. While moving with the engine yet defying collapse, the Radiator Hose maintains coolant speed at a high level, contributing to the timely opening of the thermostat and allowing the turbocharged engines typical of highly Audi models to remain within their optimum efficiency and safe temperature range. An exterior with special ribbing encourages heat dissipation as well as reducing noise and vibration, a fact that has led to the reputation of the piece in enthusiast circles as one of the highly silently heroic components in any Audi's cooling circuit. Visual inspection is easy and quick, and by changing it at the interval stated in the service booklet, the Radiator Hose prevents steam, bulged cylinder heads, and roadside headaches. Its combination of power, flexibility and wide coverage of models makes an otherwise unrecognized tube an actual performance partner to all the daily-driven A4s.
