The purpose of a car’s radiator is to prevent the engine from overheating. Unfortunately, radiators can also encounter problems, which can lead to significant damages and extensive auto repairs if not addressed promptly. To help you care for your vehicle, here are a few red flags that can point to an issue with your unit.

3 Signs of a Failing Radiator

1. Sludge Buildup

Radiator coolant is usually a bright red, green, or yellow shade, but it will become discolored if it’s become compromised. A buildup of contaminants like rust, oil, and minerals inside the radiator can turn the coolant into a sludge. This can clog the heater core, which can cause the engine to overheat and lead to expensive auto repairs. 

2. Leaking Coolant

However, if you frequently have to add coolant to your car because the levels are too low, your radiator system may be leaking. If you continue driving with low coolant, the vehicle will soon overheat, so it will need immediate attention from an auto professional. 

3. Frequent Overheating

Every engine is designed to handle a specific operating temperature, which is controlled by the radiator. If this part is malfunctioning or leaking coolant, the vehicle will frequently overheat because it won't keep the engine cool enough to function efficiently. While overheating doesn’t guarantee your radiator has failed, it’s a sign that it may not be running effectively, which requires attention.
