Why is the coolant light on my Pontiac dashboard on?

Your engine might be about to overheat. If your low coolant light is on, pull over in a safe area and wait for your engine temperature to go down. Once it’s safe to do so, bring your car to your nearest Firestone Complete Auto Care to have the coolant system inspected.

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.

When should my Pontiac Sunbird radiator be cleaned?

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

My Sunbird overheated! What can cause that?

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

What is making my Sunbird radiator sound like it’s boiling or rumbling?

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

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

Yes. Rust in the radiator of your Pontiac Sunbird can impair its cooling efficiency, cause leaks, and even result in complete failure of the radiator. Over time, rust can eat away at the radiator's cooling passages, forming tiny holes or cracks that can affect its operation. To help prevent rust from causing damage, you should stay on top of radiator maintenance.

Is It Time for Service on My 1991 Pontiac Sunbird Cooling System?

It can be tough to know when to have your Pontiac Sunbird radiator serviced if you don't know what it does, but you need to know the signs of radiator malfunction. The radiator is in the cooling system of your car, and it helps your engine temperature stay within a safe range. So, what happens when the radiator isn’t working quite like it should? You guessed it – your engine overheats, and it may even break down completely.

Regular, proactive service on the radiator in your 1991 Pontiac Sunbird is crucial to keep your engine in the best possible shape for years to come. In fact, Pontiac 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 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.

Radiator Repair Service for Your Pontiac Sunbird

What happens during a radiator repair service? At Firestone Complete Auto Care, we start by performing a thorough inspection of your Pontiac Sunbird 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. The water pump is one part on your 1991 Pontiac Sunbird engine 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 isn’t functioning properly, your engine won’t be able to stay within its optimal temperature range. Our technicians can take a look at your radiator’s components to ensure everything is operating as it should. From the heater core to the radiator cap, your 1991 Pontiac Sunbird is in good hands at Firestone Complete Auto Care. We stand behind our work with our Triple Promise: Fixed Right, Priced Right, Right on Time.
