Basic knowledge of the coolant liquid

Role of the coolant

Prevention from being frozen:

When the coolant liquid freezes up, the volume of liquid expands by approx 9%. When a coolant temperature goes down in the winter season, it may destroy the cylinder head and cores of the car engine and radiator respectively due to the excess in pressure.

Therefore materials with relatively low freezing points are generally used for coolant liquid. Ethylene glycol is mostly using in current time.

Prevention from getting rust:

Various metal and nonmetal materials are applying for cooling methods. When rust is generated from metal materials, it tends to block the coolant liquid flow in a radiator and the circulation of the coolant and results in the overheat. Therefore the additive with antirust effects is a must to be diluted in the coolant liquid.

Elevation of boiling point effect:

The temperature of the coolant rises gradually in time for driving for a long distance as previously written. Especially recent cars come with downsizing radiators for space-saving purposes in the engine space usually under the bonnet.

It leads to the fact that the temperature of the engine rises faster than before theoretically. As a consequence, the temperature of the coolant becomes higher as well. Therefore raw materials with a high boiling point will be utterly necessary. Ethylene glycol has a boiling point of more than 190 degrees Celsius.

The need for the courant exchange

The main ingredient of the coolant, ethylene glycol has one disadvantage. Therefore the antioxidant to prevent metal corrosion is add in coolant liquid in large quantities. If the heat of ethylene glycol is more, the additive evaporates as well. The coolant system deteriorated by heat and the oxidation progresses in accordance with time.

5 Benefits of changing coolant liquid

Removes Rust and Scale Deposit: Over time rust and scale deposits build up within the radiator of Car. A flush helps to remove these deposits which are pushing out with the old anti-freeze. This is important since these build-ups can cause overheating or even damage your car’s radiator.

Lubricate the Water Pump: The additives in the coolant lubricate the vehicle’s water pump. This will lengthen the life of the water pump.

Removes Contaminants: Flush completely drains the system of the old anti-freeze which means that any contaminants that have made their way into the system will be flushed out as well. The additives in coolant can lose important anti-corrosive properties over time which leads to the buildup of particles. Car radiator flush will remove these particles from the system.

Protect Against Rust and Foam: The new anti-freeze will have additives that help prevent rust and build up. It will also prevent foaming in the system which helps it to operate efficiently.
