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

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.

Can an antifreeze leak wait?

Notice a leaking fluid that's green, bright orange, or pink and feels sticky? It might be antifreeze. Antifreeze is toxic but has a sweet smell and taste that's attractive to many cats and dogs. Do your pets a favor and have an antifreeze leak investigated ASAP. Then hose down the driveway or garage floor!

Do Chevrolet Astro radiators need to be cleaned?

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

What is causing my Astro to overheat?

If your Chevrolet Astro 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.

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

Air pockets in your Astro’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 Astro radiator. Should I be worried?

Yes. Rust in your Chevrolet Astro 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 1990 Chevrolet Astro Cooling System

Not sure what a radiator does? That makes it difficult to know when to have your Chevrolet Astro radiator serviced, 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 1990 Chevrolet Astro is essential for long-term engine health. To keep your radiator functioning, Chevrolet recommends replacing your antifreeze or coolant at scheduled 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 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.

What to Expect from Chevrolet Astro Radiator Repair

What happens during a radiator repair service? If you bring your vehicle to Firestone Complete Auto Care, we start with a comprehensive inspection of your Chevrolet Astro’s cooling system. Then, we’ll move on to a machine-powered coolant exchange. Finally, we’ll refill the flushed sealants, lubricants and chemicals, then do a pressure check to catch any possible leaks.

Issues with your radiator often coincide with a malfunctioning water pump. Some services for your 1990 Chevrolet Astro engine can wait, but the water pump is one part that you'll want to have repaired or replaced as soon as you discover a problem with it. 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 ensure everything is operating as it should. From the radiator cap to the heater core, we’ll take excellent care of your 1990 Chevrolet Astro at Firestone Complete Auto Care. Every job we do is backed by our Triple Promise: Fixed Right, Priced Right, Right on Time.
