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.

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.

Do GMC G1500 radiators need to be cleaned?

Cleaning your car shouldn’t be limited to the parts you can see. Regular cleaning is good for your radiator, too! When you take your GMC G1500 in for routine maintenance or service, it could be a good idea to opt for a radiator cleaning, too.

My G1500 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 G1500 engine to overheat.

My G1500 radiator sounds like it's rumbling or boiling! What's up?

There could be air pockets in your G1500’s cooling system. You might also have a clogged radiator or faulty radiator cap (this last one is an easy fix!).

Yes. Having rust in your GMC G1500 radiator can cause leaks, a reduction in cooling efficiency, and even radiator failure.
