Water coolant is not replaced for a long time, the color of water in the reservoir will change from translucent green to brown and slightly turbid. What’s up? 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.

Workshops are usually recommended engine coolant should be replaced every 2-3 years, although some are able to five years. Engine coolant is a mixture of water danethylene 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. Just a little swallowed, can kill pets. Therefore suggested to replace the engine coolant in the workshop. 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 radioator rubber cap. If damaged, replace it just take cheap investment for an expensive machine.
