The engine in your car produces considerable heat during operation, and the cooling system helps regulate the temperature so that parts aren't permanently damaged. This system relies on a coolant, which absorbs heat from the engine and travels into the radiator, which is an auto part that sits behind the grille and removes heat from the refrigerant. Then, the process repeats. Without a functioning radiator, your car cannot operate properly, and below are several indications you may need a new one.

How Can You Tell a Car's Radiator Is Failing?

1. Overheating

On the dashboard, there is a gauge near the odometer that indicates the engine's temperature. Generally, the needle should never exceed the halfway point. If it reaches into the red area, your engine is overheating. You might also notice steam pouring out from beneath the hood. If adding more coolant doesn't resolve the issue, you may need to replace the radiator, as there could be damage to the cooling fins inside. Replacing the radiator is a more cost-effective process than repairing the damage because the fins are often a sign of a larger problem with the system.

2. Leaking Coolant

One of the most common signs of a refrigerant leak is the appearance of fluid spots beneath the vehicle. This substance is typically bright green, so you might notice small pools of moisture in this color on the pavement near the front of the vehicle. You can positively identify a leak by checking the level in the coolant reservoir. If the level falls below the fill line and depletes quickly after you replenish the fluid, this indicates it is leaking. If cracks and holes in the radiator are responsible for the leak, you may need to replace this auto part.

3. Visible Corrosion

While the coolant often has a bright green color, it might also appear blue, yellow, or orange. If it ever takes on a rusty or murky tint, the fluid may contain rust particles, which enter the liquid when the interior of the radiator corrodes. This typically happens when the metal oxidizes after prolonged exposure to moisture and air. As it corrodes, the metal can become thin and weak, eventually creating cracks in the reservoir. If you notice discoloration accompanied by low coolant levels, you need to replace the radiator, as rust is not repairable.
