Know These 5 Symptoms Of A Clogged Radiator


If you’re having trouble with your radiator, it’s essential to know the symptoms of a clogged radiator. A clogged radiator can lead to all sorts of problems, including heat loss and engine damage. In this blog post, The Key Online will list the most common symptoms of a clogged radiator. If you’re experiencing any of these radiator symptoms, take your car in for repairs!

What causes a clogged radiator?

There are a few different things that can cause your radiator to become clogged. The most common culprit is rust. It can accumulate in your radiator over time and lead to issues. Debris is another potential reason for a blocked radiator. Your radiator could get clogged with debris if you travel on gravel roads or live in a dusty environment.

Clogged radiator symptoms:

If your radiator is clogged, you’ll likely notice one or more of the following symptoms:

Warning 01: Faulty passenger area heater

Clogged radiators often cause the heater in the passenger area to stop working. If you discover that your heater isn’t functioning as effectively as it once did, a clogged radiator may be to blame. When the fans attempt to push air into the car, it won’t be as hot as it should be since the radiator won’t get the hot coolant that generates heat.

Check your radiator to ensure it is the real source of the problem; however, the failure of the passenger area heater may be unrelated to the blocked radiator.

Warning 02: Coolant leaks

Coolant leaks are another sign that your radiator is not functioning correctly. Coolants continuously move around the engine and radiator with the aid of the water pump. Coolants will find another route when the radiator is clogged, occasionally resulting in fractures in the radiator. Under steady pressure, coolants escape via the cracks or holes on the radiator, causing leaks.

If your automobile is leaking colored liquid, it may be because your radiator is clogged and the coolants are leaking. To confirm that the leak is genuinely coming from your radiator, you can begin by checking it for holes and cracks.

Warning 03: Overheating engine

The engine will overheat if the radiator is clogged. The engine’s working temperature should be around 200 degrees Fahrenheit. When it reaches above this temperature, the coolants will no longer be able to absorb the heat properly, leading to an overheated engine.

If your car’s temperature gauge is climbing higher than usual or the engine is making strange noises, it may indicate that your radiator is clogged and needs to be checked.

Warning 04: Low coolant level

If you frequently have to top off your car’s coolant levels, it could be a sign that your radiator is not functioning correctly. A clogged radiator won’t be able to effectively circulate the coolant, leading to a drop in the coolant level.

Warning 05: Sludge or rust in the radiator

If you notice sludge or rust in your radiator, it indicates it is not being cleaned properly. Clogged radiators can cause the coolant to become dirty and full of debris, leading to rust and other problems.

Final thought:

Don’t ignore these clogged radiator symptoms! When you notice a malfunctioning radiator, inspect it as quickly as possible.
