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

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.

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.

Can Pontiac Bonneville radiators 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 Pontiac Bonneville in for routine maintenance or service, it could be a good idea to opt for a radiator cleaning, too.

Why is my Bonneville overheating?

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

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

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

Yes. Rust in the radiator of your Pontiac Bonneville 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.

When to Service Your 1991 Pontiac Bonneville Cooling System

You guessed it – your engine overheats, and it may even break down completely.

Regular, proactive service on the radiator in your 1991 Pontiac Bonneville is a huge factor in the longevity of your engine. To keep your radiator functioning, Pontiac recommends replacing your antifreeze or coolant at scheduled intervals but you can also take note of any signs your radiator is going bad.
