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.

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.

When should my GMC K1500 radiator 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 K1500 in for routine maintenance or service, it could be a good idea to opt for a radiator cleaning, too.

Why is my K1500 overheating?

Low coolant, a damaged cooling fan, a faulty water pump, a malfunctioning thermostat, or a clogged radiator could all cause your GMC K1500 engine to overheat.

Why does the radiator in my K1500 sound like it’s rumbling or boiling?

There could be air pockets in your K1500’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 K1500 radiator. Should I be worried?

Yes. Having rust in your GMC K1500 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 1988 GMC K1500 Cooling System?

It can be tough to know when to have your GMC K1500 radiator serviced if you don't know what it does, but it's still extremely important. The radiator is in the cooling system of your car, and it helps your engine temperature stay within a safe range. When the radiator isn't working properly, your engine can overheat and potentially break down.

Keeping up with regular radiator maintenance in your 1988 GMC K1500 is crucial to keep your engine in the best possible shape for years to come. In fact, GMC recommends replacing coolant/antifreeze at specific 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. As soon as you see one of these symptoms, come to your nearest Firestone Complete Auto Care for a Courtesy Check.
