Radiator failures are one of the most common reasons for breakdowns but are actually very easy to avoid. Their function is essential because they cool down the engine and prevent it from overheating.

 

How do they work?

Radiators  cool the engine by feeding coolant through the engine. The system is entirely circular:

  1. Coolant enters the engine and heats up
  2. Heated liquid is fed back into the radiator
  3. Heat is radiated back into the atmosphere
  4. Cooled coolant is fed back into the engine to repeat the process.

Radiators are often installed with an axial fan to drive air into the radiator  and a water pump to force the coolant to circulate.

 

Ways to care for car radiators

This section looks at different problems that car radiators typically encounter and suggestions for how to prevent it.

 

Low coolant Levels

Coolant is a mixture of water and anti-freeze. The anti-freeze means that the water won’t freeze at sub-zero temperatures. It also raises the boiling point. It is absolutely essential that coolant levels are checked regularly. If they are low then they will not pump a sufficient amount of liquid through the engine and radiator. This means that the engine’s temperature will continue to rise until it overheats and breaks down.

Coolant levels should be checked every month and refilled after every radiator service. On most modern cars, there is a coolant gauge next to the speedometer.

If coolant levels seem to reduce quickly then there may be a more dangerous problem that needs addressing. There may be a leak in the head gasket or heater-core. For these problems, its advised to visit a mechanic immediately.

 

Radiator Material

The radiators of older cars are often made from copper or brass because they conduct heat well. However, these materials have become more expensive in recent times. Most new cars will have radiators made from aluminium. This is cheaper and actually conducts heat far better than copper or brass. If you’re installing a new radiator in your car then make sure that it is aluminium because it will certainly last longer.
