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

Your engine might be about to overheat. If your low coolant light is on, pull over in a safe area and wait for your engine temperature to go down. Once it’s safe to do so, bring your car to your nearest Firestone Complete Auto Care to have the coolant system inspected.

What are the puddles in my driveway or garage floor?

Don’t ignore puddles on your driveway or garage floor. If you see a green, bright orange, or pink fluid puddling under your car (it might be sticky, too), it could be antifreeze that’s leaking out of the engine. Antifreeze has a sweet, attractive smell to cats and dogs (and it’s highly toxic to them), so look out for your pets! Repair any leaks as soon as possible, then carefully wash away any remaining fluid that’s left behind on the driveway or garage floor.

Can Cadillac CTS radiators be cleaned?

It could be a good idea to have your Cadillac CTS radiator cleaned out a couple of times a year, maybe at the same time as a tire rotation or oil change.

What can cause my CTS to overheat?

Low coolant, a damaged cooling fan, a faulty water pump, a malfunctioning thermostat, or a clogged radiator could all cause your Cadillac CTS engine to overheat.

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

There could be air pockets in your CTS’s cooling system. You might also have a clogged radiator or faulty radiator cap (this last one is an easy fix!).

There’s rust in my CTS radiator. Should I be worried?

Yes. Rust in your Cadillac CTS radiator could reduce cooling efficiency, cause leaks, and even lead to radiator failure. Left unchecked, rust can damage the radiator's cooling passages causing small holes or cracks in the radiator. Maintain your radiator system to help prevent rust.

When to Service Your 2006 Cadillac CTS Cooling System

If you’re not sure what the purpose of a radiator is, it’s hard to tell when to have your Cadillac CTS radiator serviced. Nonetheless, it’s vital to know what to look for. As part of your car’s cooling system, your radiator helps keep engine temperature regulated. If your radiator isn’t functioning like it’s supposed to, the engine can overheat – or worse, break down.

Staying on top of routine radiator maintenance for your 2006 Cadillac CTS is essential for long-term engine health. Cadillac recommends that you replace coolant (also called antifreeze) at certain intervals, but it’s also wise to keep an eye out for signs of a failing radiator. 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. When you experience one or more of these issues, head to your local Firestone Complete Auto Care for a Courtesy Check.

Radiator Repair Service for Your Cadillac CTS

What does radiator repair include? If you bring your vehicle to Firestone Complete Auto Care, we start with a comprehensive inspection of your Cadillac CTS’s cooling system. We’ll do a machine-powered coolant exchange on the system, and then we’ll top off or replace the fluids that were removed (like chemicals, lubricants, and sealants).

Radiator problems often go hand in hand with water pump problems. Some services for your 2006 Cadillac CTS engine can wait, but the water pump is one part that needs to be addressed ASAP once an issue is identified.

If you’re about to lose your cool over a too-hot engine, rest assured that we’re here to give your 2006 Cadillac CTS the top-notch service it needs.
