Common Porsche Cayenne Radiator Questions

• What does the coolant light on my Porsche dashboard mean? 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.
• 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 Cayenne radiators need to be cleaned? It could be a good idea to have your Porsche Cayenne radiator cleaned out a couple of times a year, maybe at the same time as a tire rotation or oil change.
• My Cayenne 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 Porsche Cayenne engine to overheat.
• My Cayenne radiator sounds like it's rumbling or boiling! What's up? Air pockets in your Cayenne’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.
• Is it bad to have rust on my Cayenne radiator? Yes. Having rust in your Porsche Cayenne 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.
