How the importance of the engine coolant can we see from the following stories and articles.

Engine Coolant

This is the story of a friend and his favorite vehicle. Tiny car was treated seriously. Never forget, how busy, to check the major car fluids, including engine coolant. Through the reservoir near the radiator, he could see if it needs to add water or not. If necessary, turn the faucet to stay and poured water into the container. Wrong!

Apparently not, after a while, he was suspicious of the color of water in the reservoir is changing from translucent green to brown and slightly turbid. What’s up? Customers in the shop she got her answers.

Engine coolant is not good used condition and began to cause rust in the coolant system. The solution must be drained and replaced with new ones. If allowed, the rust will spread to the cooling system and engine, the cost of the repairs made perforated bags.

Workshop recommended the engine coolant should be replaced every 2 – 3 years, although there can be five years. Engine coolant is a mixture of water and ethylene glycol. These chemicals are functioning so that coolant does not freeze, preventing the boiling water (boiling point reached 130 C) so as not to overheat quickly, and with other additives to prevent rust.

Engine coolant must also match the raw materials were highly diverse cooling systems, plus be able to transfer heat efficiently, prevent corrosion and provide lubrication to water pump baffle-insulator. When conditions are good the color green.

Engine cooling system is built from a series of complex components and materials. Aluminum, cast iron, steel, stainless steel, copper, brass, rubber and plastics, is a constituent.

When two different types of metals contact with each other through the intermediary fluid will behave like battery acid, an electron-proton exchange. This is what triggers metal corrosion, replacing the engine coolant on a regular basis to prevent excessive formation of acid in the engine cooling system while helping to reduce corrosion.

Ethylene glycol is a toxic chemical compounds. Few can be drunk can kill pets. Therefore suggested to replace the engine coolant in the garage, workshops will remove the old engine coolant, clean the engine cooling system and fill the new coolant.

In developed countries, many workshops have engine coolant recycling system. In this system, water is separated and channeled out, while its chemical compounds reprocessed.

Routine maintenance becomes an easy way to treat the cooling system. The simplest way, check the height of the liquid with a view of the tank, If less than the minimum limit, add a little water to exceed the minimum limit. Few months, attention radiators rubber cap. If damaged, replace it just take cheap investment for an expensive machine.
