Without the radiator, your car would overheat, causing significant damage to the engine. This device uses a series of tubes and fins to remove heat from the coolant so that it can circulate through the engine and cool it down. However, it can occasionally require auto repairs when the hoses and other aspects break. To help you avoid significant engine problems, here are several warnings that your radiator is broken.

When Should You Visit a Mechanic to Fix a Radiator?

1. Leaking Coolant

The coolant extracts heat from the engine and keeps it at a safe temperature. However, if there’s a weak connection point in the radiator, this auto fluid will leak out. If you spot a green, pink, or orange stain under your vehicle, or smell a sweet odor inside your car, you likely have a coolant leak. Low coolant levels indicate a serious issue that needs prompt attention.

2. Overheating

Usually, you can catch overheating when the temperature gauge on your dashboard steadily climbs toward the red zone. In some cases, smoke will billow out from under the hood, as well. If you notice any of these signs, stop the car immediately to avoid long-term damage.

3. Heater Problems

When you turn on the heat in your car, it should not produce cool air from the vents. If it does, this lack of warmth can occur when a dirty radiator processes too much debris, clogging the heater core. It's also possible that the faulty radiator overheated, causing the water pump that serves the heater core to melt.

4. Damaged Fins

The aluminum fins on a radiator increase the coolant’s exposure to open air, promoting heat exchange. When something bends or breaks these fins, your car has a much higher chance of overheating. Sometimes, a professional may can restore the fins to an acceptable condition. However, if your radiator is significantly old, you may need to replace the entire component.
