Why is the coolant light on my Dodge 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.

Is rust in my Diplomat radiator bad?

Yes. Having rust in your Dodge Diplomat radiator can cause leaks, a reduction in cooling efficiency, and even radiator failure. If rust is left untreated, it can corrode the radiator's cooling passages, causing small cracks or holes that can significantly impact the radiator's ability to function. To help prevent rust from becoming a major issue, it's important to properly maintain your radiator system.

When to Service Your 1989 Dodge Diplomat Cooling System

It can be tough to know when to have your Dodge Diplomat radiator serviced if you don't know what it does, but you need to know the signs of radiator malfunction. The radiator is in the cooling system of your car, and it helps your engine temperature stay within a safe range. When the radiator isn't working properly, your engine can overheat and potentially break down.

Staying on top of routine radiator maintenance for your 1989 Dodge Diplomat is crucial to keep your engine in the best possible shape for years to come. Dodge recommends that you replace coolant (also called antifreeze) at certain intervals, but you can also take note of any signs your radiator is going bad. You might be driving around (or about to be stranded) with a failing radiator 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. As soon as you see one of these symptoms, come to your nearest Firestone Complete Auto Care for a Courtesy Check.
