Why is the coolant light on my Audi dashboard on?

Pay attention to the temperature gauge and lights on your dashboard. If a low coolant warning light comes on or your dashboard temperature gauge keeps rising, it’s likely that your engine is about to overheat (and could leave you stranded on the road). Wait for the engine to cool down, then have your coolant system checked immediately at your nearest Firestone Complete Auto Care.

When to Service Your 2002 Audi S4 Cooling System

If you’re not sure what the purpose of a radiator is, it’s hard to tell when to have your Audi S4 radiator serviced. Nonetheless, it’s vital to know what to look for. Your radiator is part of the cooling system. It helps regulate engine temperature. So, what happens when the radiator isn’t working quite like it should? You guessed it – your engine overheats, and it may even break down completely.

Staying on top of routine radiator maintenance for your 2002 Audi S4 is essential for long-term engine health. In fact, Audi recommends replacing coolant/antifreeze at specific intervals, but it’s a good idea to keep your eyes open for any indication that your radiator is failing. You could be on the verge of a radiator-induced engine breakdown if you notice a low coolant light or higher-than-normal engine temperatures on your dashboard, or if you spot coolant leaks coming from your car. Visit your local Firestone Complete Auto Care for a Courtesy Check at the first sign of one of these issues.
