1. Your Car Overheats Frequently

One of the most apparent signs of a problem with your radiator is if your car overheats frequently. If the temperature gauge on your dash creeps into the red more often than usual, you should get your radiator checked out. If you’re unsure what the temperature gauge looks like, it’s usually a red needle on the dashboard that points to a number in the red zone. If the arrow indicates the scale’s hot side, it’s time to check your radiator.

A faulty radiator can overheat your engine, leading to severe damage. When your car overheats, pull over and turn off the engine as soon as possible.

2. You See Steam Or Coolant Coming From Under The Hood

One of the most obvious signs of something wrong with your radiator is when you see steam coming out under the hood or the coolant leaking under the carriage. If your car is leaking coolant, the radiator likely has a problem.

Coolant leaks can be caused by various things, including a cracked radiator, a loose hose, or a clamp. If you see coolant leaking from your car, take it to a mechanic as soon as possible to have it checked out.

A cracked radiator can cause your engine to overheat and can lead to severe damage. If there is a crack, you need a new radiator.

3. The Engine Warning Light Is On

Your radiator is failing when the engine warning light comes on. It may signal low coolant levels, which can cause your engine to overheat. Check your coolant levels and take your car to a mechanic if you see the engine warning light come on.

4. You Hear Strange Noises Coming From Under The Hood

If you hear strange noises from under the hood, it could be a sign that the radiator is beginning to fail or the radiator hose is collapsing or kinked. These noises can range from a low rumbling to a high-pitched squealing sound. If you hear any strange noises, be sure to take your car to a mechanic right away.

These signs indicate that the radiator is failing. A failing radiator can cause severe damage to your engine and lead to expensive repairs. It’s best to catch the problem early and nip it in the bud.
