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

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.

Is an antifreeze leak dangerous?

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 G3500 radiators be cleaned?

It could be a good idea to have your GMC G3500 radiator cleaned out a couple of times a year, maybe at the same time as a tire rotation or oil change.

Why is my G3500 overheating?

If your GMC G3500 engine overheats, it could be because of a clogged radiator, a damaged thermostat, a faulty cooling fan, a malfunctioning water pump, or low coolant levels.

There could be air pockets in your G3500’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 G3500 radiator. Should I be worried?

Yes. Rust in your GMC G3500 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 1985 GMC G3500 Cooling System

Not sure what a radiator does? That makes it difficult to know when to have your GMC G3500 radiator serviced, but it’s vital to know what to look for. Your radiator is part of the cooling system. It helps regulate engine temperature. So, what happens when the radiator isn’t working quite like it should? You guessed it – your engine overheats, and it may even break down completely.

Regular, proactive service on the radiator in your 1985 GMC G3500 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 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.
