The radiator keeps a vehicle’s engine from overheating. Coolant, which is a thick, protective liquid that maintains safe engine temperatures, passes through a radiator’s fan fins so that heat flows away from the engine. If this internal cooling system isn’t working properly, your car is vulnerable to overheating. Here are several signs that may require a trip to an auto repair shop for a thorough radiator diagnosis.

What Are Some Indicators of a Radiator Problem? 

1. Coolant Leaks

Depending on the brand, coolant is typically green, red, or yellow. If you notice any of these colors puddled under your vehicle, there could be a leak.

The culprit might be a cracked or damaged radiator. An auto repair technician will inspect the component and identify the leak’s source.

2. Sludge 

When a radiator is malfunctioning, deposits and other contaminants can create sludge inside the system. The coolant won’t be able to maintain the engine’s temperature due to blockage. A clear sign that sludge is present in the radiator is a change in the coolant’s color from the typical shades of red, green, or yellow to a dark brown or rusty hue.

3. Overheated Engine

Radiator failure is one of the main causes of an overheated engine. When it stops working, there’s likely a breakdown somewhere between the coolant channel and the engine.

Overheating problems require immediate attention at a professional auto repair shop. If you continue to drive your vehicle with a heated engine, extensive radiator damage can occur. 

4. Inadequate Coolant Amount

In many vehicles, a warning light will appear on the dashboard if coolant levels are low. The issue may be triggered by a leak somewhere in the radiator.

The solution might be just refilling coolant to the recommended level. However, if the warning light continues to flash, have your radiator inspected by an auto repair technician to get to the root of the problem.
