2021 Toyota Corolla Radiator Repair & Service

Common Toyota Corolla Radiator Questions

• What does the coolant light on my Toyota 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 Toyota Corolla radiators need to be cleaned? It could be a good idea to have your Toyota Corolla radiator cleaned out a couple of times a year, maybe at the same time as a tire rotation or oil change.
• Why is my Corolla overheating? Low coolant, a damaged cooling fan, a faulty water pump, a malfunctioning thermostat, or a clogged radiator could all cause your Toyota Corolla engine to overheat.
• Why does the radiator in my Corolla sound like it’s rumbling or boiling? There could be air pockets in your Corolla’s cooling system. You might also have a clogged radiator or faulty radiator cap (this last one is an easy fix!).
• There’s rust in my Corolla radiator. Should I be worried? Yes. Rust in the radiator of your Toyota Corolla 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.
