A functioning radiator is what prevents your car from overheating, putting it at risk for engine fires. Your cooling system often sends out subtle distress signs when there’s an issue with your radiator, so understanding what to look for can help you know when to get repairs. Here are a few of the signs that your vehicle may be experiencing radiator troubles.

3 Symptoms of a Failing Radiator

1. Rust Contamination in Coolant

Your coolant can be contaminated when dirt particles on the cap fall into it, turning it into a brown sludge. Rust around the radiator, typically caused by moisture, eventually corrodes the equipment, causing even more contamination. If your cooling system requires frequent flushing and new coolants to cool your engine, your radiator may be rusted and contaminating its liquids, so replace the part.

2. Green Liquid Under the Car

Routine wear, accidents, and flying stones on the road could puncture the your radiator or a hose under your car, resulting in leaks. If you notice green puddles where you park, the odd-colored liquid is most likely coolant leaking from a crack. Leaks bring down your coolant levels, which could cause your engine to overheat, so take your car to get radiator repairs immediately.

3. Thermostat Malfunctions

When your engine reaches a certain temperature, a sensor prompts the thermostat to open, letting coolant flow to and from the radiator. If this sensor is damaged, the thermostat can stay in the open or closed position, leading to cooling issues and engine overheating. If your temperature gauge is frequently high for no apparent reason, you could have a damaged thermostat, so seek assistance.
