Questions About Toyota Prius Radiators

• Why is the coolant light on my Toyota dashboard on? 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.
• Is an antifreeze leak dangerous? 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.
• Can Toyota Prius radiators be cleaned? It could be a good idea to have your Toyota Prius radiator cleaned out a couple of times a year, maybe at the same time as a tire rotation or oil change.
• Why is my Prius overheating? Your Toyota Prius 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 Prius sound like it’s rumbling or boiling? If your radiator sounds like it's boiling or rumbling, you could have air pockets in the cooling system of your Prius. You might also have a damaged radiator cap (super easy to fix!) or a clogged radiator.
• Is rust in my Prius radiator bad? Yes. Rust in your Toyota Prius 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.
