There are many car maintenance tasks that people avoid. This results in costly repairs and replacement overtime. One such maintenance measure is flushing your car’s coolant. Did you know that the cooling system inside modern cars has not changed from how it was a hundred years ago?

Despite the modern ones being more efficient, they still have the same coolant that circulates through the engine. To understand why flushing the coolant inside your car is important, you need to first get an overview of the car’s cooling system.

Cooling System

The cooling system’s job is to moderate the heat levels that you generate from the engine, and dissipate it through a heat exchanger, which is the radiator. The coolant inside the radiator carries the heat generated in the engine and transfers it to the radiator.

Why Flushing the Coolant is Important?

As the coolant ages, it starts to collect heavy metal solids and other properties of metals. Once this happens, the fluid loses its capacity to lubricate the water pumps since it no longer has the qualities to carry surface tension.

Even if the coolant appears clear, this does not mean that it is in good condition. The heavy metal particles immersed inside the liquid coolant are mostly not visible with a naked eye since they can be broken down. A better way to check for them involves using test strips.

With the infusion of heavy metals, the coolant loses its ability to contact the walls of the radiator tubes, making it flow with lowered down surface tension. Without sufficient surface tension, the coolant does not flow as smoothly as you would like, and this removes its ability to transfer heat efficiently to the radiator.

Heavy metals and Radiator Damage

As the coolant circulates around your engine and radiator, it chisels away at the cast iron and aluminum, along with other metals that are inside the system. The tiny particles of that metal do not have anywhere to go, until you turn off the engine.

The small solids that are stemming from all the damage from the fluid will drop down and solidify at the bottom of the radiator. This settling down at the bottom is something that technicians will refer to as concrete.

The overtime accumulation of heavy metals inside the radiator will not only damage it, but also reduce its capacity by a large margin. With the radiator capacity down, your car can experience overheating problems since the coolant is a huge part of the cooling system.

Ultimately, not flushing out your cooling system frequently enough will cause overheating problem, along with damage to the seals, causing bearing or seal failure. This is why it is important that you make timely coolant replacements so that you do not give it the time to chisel away at the seals for too long.
