What does the coolant light on my GMC dashboard mean?

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?

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.

Do GMC G1500 radiators need to be cleaned?

It could be a good idea to have your GMC G1500 radiator cleaned out a couple of times a year, maybe at the same time as a tire rotation or oil change.

What can cause my G1500 to overheat?

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?

If your radiator sounds like it's boiling or rumbling, you could have air pockets in the cooling system of your G1500. You might also have a damaged radiator cap (super easy to fix!) or a clogged radiator.

There’s rust in my G1500 radiator. Should I be worried?

Yes. Having rust in your GMC G1500 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 to Service Your 1984 GMC G1500 Cooling System

It can be tough to know when to have your GMC G1500 radiator serviced if you don't know what it does, but you need to know the signs of radiator malfunction. As part of your car’s cooling system, your radiator helps keep engine temperature regulated. When the radiator isn't working properly, your engine can overheat and potentially break down.

Regular, proactive service on the radiator in your 1984 GMC G1500 is a huge factor in the longevity of your engine. In fact, GMC recommends replacing coolant/antifreeze at specific 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 see coolant leaks under your car, high engine temperatures, or a dashboard light that indicates low coolant. As soon as you see one of these symptoms, come to your nearest Firestone Complete Auto Care for a Courtesy Check.

GMC G1500 Coolant Fluid Exchange

What does radiator repair include? When you come to Firestone Complete Auto Care, we’ll begin your radiator repair with an in-depth inspection of the cooling system in your GMC G1500.

Issues with your radiator often coincide with a malfunctioning water pump. Some services for your 1984 GMC G1500 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. If it’s not working well (or at all), your engine can easily overheat. Our trained technicians can inspect your car’s radiator hoses and pumps to help you stay ahead of any potential engine problems. From the radiator cap to the heater core, we’re here to give your 1984 GMC G1500 the top-notch service it needs.
