When to Service Your 2006 Cadillac STS Cooling System

It can be tough to know when to have your Cadillac STS radiator serviced if you don't know what it does, but it's still extremely important. Your radiator is part of the cooling system. It helps regulate engine temperature. If your radiator isn’t functioning like it’s supposed to, the engine can overheat – or worse, break down.

Regular, proactive service on the radiator in your 2006 Cadillac STS is crucial to keep your engine in the best possible shape for years to come. To keep your radiator functioning, Cadillac recommends replacing your antifreeze or coolant at scheduled intervals but it’s also wise to keep an eye out for signs of a failing radiator. 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.

Radiator Repair Service for Your Cadillac STS

What does radiator repair include? At Firestone Complete Auto Care, we start by performing a thorough inspection of your Cadillac STS cooling system. We then do a machine-powered radiator exchange, replenish flushed chemicals, sealants, and lubricants, and then pressure check for leaks.

Issues with your radiator often coincide with a malfunctioning water pump. Some services for your 2006 Cadillac STS engine can wait, but the water pump is one part that you can't put off repairing or replacing. The role of the water pump is to keep coolant circulating in your engine, radiator, and hoses. Without it, your engine won't maintain its optimal temperature. Our technicians can take a look at your radiator’s components to ensure everything is operating as it should. From the radiator cap to the heater core, your 2006 Cadillac STS is in good hands at Firestone Complete Auto Care. Every job we do is backed by our Triple Promise: Fixed Right, Priced Right, Right on Time.
