To help prevent rust from becoming a major issue, it's important to properly maintain your radiator system.

When to Service Your 2006 Cadillac DTS Cooling System

It can be tough to know when to have your Cadillac DTS radiator serviced if you don't know what it does, but 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.

Keeping up with regular radiator maintenance in your 2006 Cadillac DTS is a huge factor in the longevity of your engine. In fact, Cadillac 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. Your radiator could be close to causing an engine breakdown if you notice leaking coolant, overheating, or an illuminated low coolant dashboard light. When you experience one or more of these issues, head to your local Firestone Complete Auto Care for a Courtesy Check.
