Why is the coolant light on my GMC dashboard on?

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.

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.

When should my GMC C2500 radiator be cleaned?

It could be a good idea to have your GMC C2500 radiator cleaned out a couple of times a year, maybe at the same time as a tire rotation or oil change.

My C2500 overheated! What can cause that?

Your GMC C2500 engine could overheat due to low coolant, a clogged radiator, a damaged water pump, a malfunctioning cooling fan, or a faulty thermostat.

What is making my C2500 radiator sound like it’s boiling or rumbling?

There could be air pockets in your C2500’s cooling system. You might also have a clogged radiator or faulty radiator cap (this last one is an easy fix!).

Should I be concerned about rust in my C2500 radiator?

Yes. Having rust in your GMC C2500 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.

Is It Time for Service on My 1999 GMC C2500 Cooling System?

Not sure what a radiator does? That makes it difficult to know when to have your GMC C2500 radiator serviced, 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.

Keeping up with regular radiator maintenance in your 1999 GMC C2500 is a huge factor in the longevity of your engine. To keep your radiator functioning, GMC recommends replacing your antifreeze or coolant at scheduled intervals but it’s a good idea to keep your eyes open for any indication that your radiator is failing. You could be on the verge of a radiator-induced engine breakdown if you notice leaking coolant, overheating, or an illuminated low coolant dashboard light. When you experience one or more of these issues, head to your local Firestone Complete Auto Care for a Courtesy Check.
