What does the coolant light on my Porsche 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.

Do Porsche 911 radiators need to be cleaned?

To keep your Porsche 911 radiator running well, it’s wise to get it cleaned out a few times a year.

What can cause my 911 to overheat?

Your Porsche 911 engine could overheat due to low coolant, a clogged radiator, a damaged water pump, a malfunctioning cooling fan, or a faulty thermostat.

Why does the radiator in my 911 sound like it’s rumbling or boiling?

There could be air pockets in your 911’s cooling system. You might also have a clogged radiator or faulty radiator cap (this last one is an easy fix!).

Is rust in my 911 radiator bad?

Yes. Having rust in your Porsche 911 radiator can cause leaks, a reduction in cooling efficiency, and even radiator failure. If rust is left untreated, it can corrode the radiator's cooling passages, causing small cracks or holes that can significantly impact the radiator's ability to function. To help prevent rust from becoming a major issue, it's important to properly maintain your radiator system.

Is It Time for Service on My 1991 Porsche 911 Cooling System?

Not sure what a radiator does? That makes it difficult to know when to have your Porsche 911 radiator serviced, but it's still extremely important. The radiator is in the cooling system of your car, and it helps your engine temperature stay within a safe range. 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 1991 Porsche 911 is a huge factor in the longevity of your engine. Porsche recommends that you replace coolant (also called antifreeze) at certain intervals, but it’s also wise to keep an eye out for signs of a failing radiator. 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. As soon as you see one of these symptoms, come to your nearest Firestone Complete Auto Care for a Courtesy Check.

Of all the parts in your 1991 Porsche 911 engine, the water pump is one that you'll want to have repaired or replaced as soon as you discover a problem with it. This pump ensures that coolant is always flowing through the radiator, hoses, and engine. If it isn’t functioning properly, your engine won’t be able to stay within its optimal temperature range. Let our technicians examine your radiator pumps and hoses to help make sure everything is in working order. If you’re about to lose your cool over a too-hot engine, rest assured that your 1991 Porsche 911 is in good hands at Firestone Complete Auto Care. After all, we know it’s not just a car.
