The radiator is responsible for cooling the engine, which generates a significant amount of heat while burning fuel. This essential auto part contains a thermostat that detects when temperatures rise to unsafe levels, causing water and coolant to release. When the radiator fails, your engine may overheat and cause stalling, breakdowns, and mechanical damage. Prevent problems by knowing how to identify the following red flags of radiator failure.

3 Signs You Need a New Radiator

1. Corrosion

Corrosion may develop within your radiator when hoses become dislodged or damaged, causing fluids to leak onto hot engine components. As a result, these metal auto parts will develop rust spots, which prevent the engine from operating with ease. Corrosion may cause your engine to seize, leading to stalling or breakdowns. If your radiator is corroded, replace it immediately.

2. Low Coolant

While you may need to refill the reservoir with more freon, low coolant levels may also indicate that your radiator has holes or cracks. Check the ground beneath the vehicle for bright pink, yellow, or green spots, which typically indicate radiator fluid leaks. If there’s spotting coupled with low coolant levels, your radiator is likely damaged, and you’ll need a replacement.

3. Overheating

When your vehicle is overheating, you’ll notice the dashboard temperature gauge rising, and there may be steam emerging from the hood. Cars that are overheated can stall, so make sure your vehicle is inspected annually to ensure the radiator is functional.
