Bad Radiator Symptoms: Common Signs that Your Radiator is Failing

  1. Overheating engine. A common sign that something is wrong with the radiator is when your engine starts to overheat.
  2. Leaks.
  3. Shifting issues.
  4. Fluid discoloration.
  5. Exterior fins blocked.
  6. Passenger heater not functioning.
  7. Checking the Cooling System.
  8. Heater core.

What happens when a radiator goes bad?

As the radiator goes bad, it will turn a rusty or oil color from contaminants. If not flushed periodically, this dirty coolant turns into sludge. By the time it turns to sludge, it will not flow properly to cool the engine efficiently and you may end up with extensive damage to the engine and transmission.

How do u unclog a radiator?

To unclog the radiator, you will need to drain out the old coolant, then force water through the radiator to flush out the sediments. Refill the radiator with fresh radiator coolant fluid that contains antifreeze, and your radiator will be good to go for another few years!

Why is one side of my radiator cold?

One cold radiator usually indicates that either there is air in the system or there is a stuck valve within that radiator. This is particularly the case in an old radiator. To check if the valve is stuck, you can remove the rotatable head on the TRV to reveal a raised pin beneath it.

How can you tell if your car has a bad radiator?

It flows freely between the radiator and the coolant passages located in your car’s engine. If you have a bad radiator, deposits and sludge can contaminate the coolant and turn it into a rusty color—it may even look like oil. Look in your coolant overflow tank and inspect the color.

Where does the coolant go when a radiator leaks?

The coolant flows through the radiator, so if there is a leak in the radiator, coolant will leak onto the floor underneath the vehicle. It may be while you are driving or while your vehicle is parked.

Why are the fins on my radiator not working?

Radiators need maximum airflow for proper cooling. The thin tubes running in the front, the ones that look like fins, carry the hot coolant away from the engine. When you drive, air passes over the fins to lower the temperature of the coolant. If these fins become clogged by debris, leaves, bugs, or dirt, airflow can become compromised.

What happens to the coolant in a car when it goes bad?

The coolant in your vehicle should be yellow or green or red normally. As the radiator goes bad, contaminants discolor the fluid making it a rusty or oil color. This turns into sludge and the fluid will not be able to cool the engine efficiently because it will not drain properly and remain in the radiator.
