What does an illuminated coolant temperature light mean for my Cadillac?

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.

Do your pets a favor and have an antifreeze leak investigated ASAP. Then hose down the driveway or garage floor!

Do Cadillac CTS radiators need to be cleaned?

Why is my CTS overheating?

If your Cadillac CTS engine overheats, it could be because of a clogged radiator, a damaged thermostat, a faulty cooling fan, a malfunctioning water pump, or low coolant levels.

What can cause a CTS radiator to make boiling or rumbling sounds?

Air pockets in your CTS’s cooling system may cause a rumbling or boiling noise. You could also have a clogged radiator or simply need to replace the radiator cap.

Is rust in my CTS radiator bad?

Yes. If you have rust in your Cadillac CTS radiator, it could cause leaks, negatively impact cooling efficiency, and eventually lead to radiator failure.

When Does My 2008 Cadillac CTS Radiator Need Service?

It can be tough to know when to have your Cadillac CTS radiator serviced if you don't know what it does, but it’s vital to know what to look for. 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 Cadillac CTS is a huge factor in the longevity of your engine. Cadillac recommends that you replace coolant (also called antifreeze) at certain 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 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.
