Is It Time for Service on My 2008 Audi S5 Cooling System?

It can be tough to know when to have your Audi S5 radiator serviced if you don't know what it does, but you need to know the signs of radiator malfunction. As part of your car’s cooling system, your radiator helps keep engine temperature regulated. When the radiator isn't working properly, your engine can overheat and potentially break down.

Staying on top of routine radiator maintenance for your 2008 Audi S5 is crucial to keep your engine in the best possible shape for years to come. To keep your radiator functioning, Audi recommends replacing your antifreeze or coolant at scheduled intervals but it’s a good idea to keep your eyes open for any indication that your radiator is failing. You might be driving around (or about to be stranded) with a failing radiator if you see coolant leaks under your car, high engine temperatures, or a dashboard light that indicates low coolant. Visit your local Firestone Complete Auto Care for a Courtesy Check at the first sign of one of these issues.

Audi S5 Coolant Fluid Exchange

What’s included in a radiator repair service? When you come to Firestone Complete Auto Care, we’ll begin your radiator repair with an in-depth inspection of the cooling system in your Audi S5. We’ll do a machine-powered coolant exchange on the system, and then we’ll top off or replace the fluids that were removed (like chemicals, lubricants, and sealants). Lastly, we’ll perform a pressure check to look for leaks.

Issues with your radiator often coincide with a malfunctioning water pump. Some services for your 2008 Audi S5 engine can wait, but the water pump is one part that needs to be addressed ASAP once an issue is identified. This vital part keeps coolant moving through the engine, hoses, and radiator. Without it, your engine won't maintain its optimal temperature. Our technicians can take a look at your radiator’s components to help you stay ahead of any potential engine problems. If you’re about to lose your cool over a too-hot engine, rest assured that your 2008 Audi S5 is in good hands at Firestone Complete Auto Care. After all, we know it’s not just a car. It’s your car.
