Is It Time for Service on My 2018 Audi A4 Cooling System?

Staying on top of routine radiator maintenance for your 2018 Audi A4 is crucial to keep your engine in the best possible shape for years to come. 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.
