What does the coolant light on my Isuzu dashboard mean?

Pay attention to the temperature gauge and lights on your dashboard. If a low coolant warning light comes on or your dashboard temperature gauge keeps rising, it’s likely that your engine is about to overheat (and could leave you stranded on the road). Wait for the engine to cool down, then have your coolant system checked immediately at your nearest Firestone Complete Auto Care.

What are the puddles in my driveway or garage floor?

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.

Can Isuzu Impulse radiators be cleaned?

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

Why is my Impulse overheating?

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

My Impulse 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 Impulse. You might also have a damaged radiator cap (super easy to fix!) or a clogged radiator.

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

Yes. Rust in your Isuzu Impulse 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.

Is It Time for Service on My 1990 Isuzu Impulse Cooling System?

It can be tough to know when to have your Isuzu Impulse radiator serviced if you don't know what it does, but you need to know the signs of radiator malfunction. Your radiator is part of the cooling system. It helps regulate engine temperature. If your radiator isn’t functioning like it’s supposed to, the engine can overheat – or worse, break down.

Staying on top of routine radiator maintenance for your 1990 Isuzu Impulse is a huge factor in the longevity of your engine. Isuzu recommends that you replace coolant (also called antifreeze) at certain intervals, but you can also take note of any signs your radiator is going bad. You could be on the verge of a radiator-induced engine breakdown if you see coolant leaks under your car, high engine temperatures, or a dashboard light that indicates low coolant. When you experience one or more of these issues, head to your local Firestone Complete Auto Care for a Courtesy Check.

Radiator Repair Service for Your Isuzu Impulse

What’s included in a radiator repair service? If you bring your vehicle to Firestone Complete Auto Care, we start with a comprehensive inspection of your Isuzu Impulse’s 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.

Issues with your radiator often coincide with a malfunctioning water pump. Some services for your 1990 Isuzu Impulse engine can wait, but the water pump is one part that needs to be addressed ASAP once an issue is identified. The role of the water pump is to keep coolant circulating in your engine, radiator, and hoses. Without it, your engine won't maintain its optimal temperature. Let our technicians examine your radiator pumps and hoses to ensure everything is operating as it should. When it comes to radiator service and repair, we’ll take excellent care of your 1990 Isuzu Impulse at Firestone Complete Auto Care. After all, we know it’s not just a car. It’s your car.
