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

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?

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 Isuzu Impulse radiators need to be cleaned?

To keep your Isuzu Impulse radiator running well, it’s wise to get it cleaned out a few times a year.

My Impulse overheated! What can cause that?

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

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

Air pockets in your Impulse’s cooling system may cause a rumbling or boiling noise. You could also have a clogged radiator or simply need to replace the radiator cap.

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

Yes. If you have rust in your Isuzu Impulse radiator, it could cause leaks, negatively impact cooling efficiency, and eventually lead to radiator failure. Left unaddressed, radiator rust can erode the cooling passages, creating cracks or small holes. Properly maintaining your radiator system can help stop it from rusting.

When Does My 1989 Isuzu Impulse Radiator Need Service?

If you’re not sure what the purpose of a radiator is, it’s hard to tell when to have your Isuzu Impulse radiator serviced. Nonetheless, 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 1989 Isuzu Impulse is crucial to keep your engine in the best possible shape for years to come. To keep your radiator functioning, Isuzu recommends replacing your antifreeze or coolant at scheduled 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. When you experience one or more of these issues, head to your local Firestone Complete Auto Care for a Courtesy Check.

What to Expect from Isuzu Impulse Radiator Repair

What’s included in a radiator repair service? At Firestone Complete Auto Care, we start by performing a thorough inspection of your Isuzu Impulse cooling system. We’ll do a machine-powered coolant exchange on the system, and then we’ll top off or replace the fluids that were removed (like chemicals, lubricants, and sealants). Lastly, we’ll perform a pressure check to look for leaks.

Radiator problems often go hand in hand with water pump problems. Some services for your 1989 Isuzu Impulse engine can wait, but the water pump is one part that needs to be addressed ASAP once an issue is identified. This pump ensures that coolant is always flowing through the radiator, hoses, and engine. If it’s not working well (or at all), your engine can easily overheat. Let our technicians examine your radiator pumps and hoses to help you stay ahead of any potential engine problems. From the radiator cap to the heater core, your 1989 Isuzu Impulse is in good hands at Firestone Complete Auto Care. After all, we know it’s not just a car. It’s your car.
