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

If the coolant light illuminates on your dashboard, your engine could be overheating. Pull over to a safe area and wait for the engine to cool down. Then, head to your nearest Firestone Complete Auto Care for a coolant system check.

Can an antifreeze leak wait?

It's better to get it fixed sooner than later. Antifreeze is toxic if consumed, but its smell can attract cats and dogs. Keep your whole family safe by repairing antifreeze leaks ASAP and thoroughly hosing down your parking spot to get rid of any lingering residue on the ground.

Can GMC Envoy radiators be cleaned?

To keep your GMC Envoy radiator running well, it’s wise to get it cleaned out a few times a year.

My Envoy overheated! What can cause that?

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

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

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

Is it bad to have rust on my Envoy radiator?

Yes. Having rust in your GMC Envoy 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 Does My 2008 GMC Envoy Radiator Need Service?

Not sure what a radiator does? That makes it difficult to know when to have your GMC Envoy radiator serviced, 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. 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 2008 GMC Envoy is essential for long-term engine health. GMC 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. Your radiator could be close to causing an engine breakdown if you notice leaking coolant, overheating, or an illuminated low coolant dashboard light. As soon as you see one of these symptoms, come to your nearest Firestone Complete Auto Care for a Courtesy Check.
