Replacement of antifreeze, the basic rules

Another lesson of Physics, everyone knows that every system, doing jobs that produce heat. In some cases, this pattern can have disastrous results. One of the "organisms" where the temperature of the need to monitor very closely is the car's engine. That is to maintain an optimal temperature regime in the heart of the steel used trotter cooling system operating on fluids, a mixture based on monoetilen and monopropilenglikolya. Their function is to protect the engine from overheating and the cooling system from corrosion and freezing. Coolant should always be replaced after a certain time. In Mazda vehicles scheduled replacement coolant spend 2 years under normal use and every sixty thousand kilometers in intensive. Besides replacing antifreeze should be carried out after any kind of repair work on the cooling system. The reason is that if the coolant of their functions anticorrosion additives contained in it are deposited on the newly installed parts and create a protection against corrosion. To make the process of replacing anti-freeze has passed without any complications you should know how to approach him. To begin, you should follow some rules: 1. All work must be made with the engine shut off. After it is cool to wrap the lid of the cooling system of matter and a little provernuv it counter-clockwise, wait for the pressure. Only if the lid can be removed completely. 2. Should not be used as an antifreeze liquid containing ethanol or alcohol. In cars Mazda engine has a number of aluminum parts, easily damaged and methanol alcohol antifreeze. 3. The water in the coolant should not contain salt. This reduces the efficiency of the coolant. Familiarized with the basic guidelines for working with the cooling system and antifreeze can get to work. The process of replacing the coolant consists of a series of successive steps. The first of these is the removal of the cover of the cooling system. Next, set the container under the radiator and open the drain plug to drain radiator coolant. After the container is installed under the drain plug of the cylinder block. Once the antifreeze is drained cap on the radiator and engine block must be closed. Next, fill the cooling system is carried out. To do this, first in the expansion tank is filled with 2 liters of water, and then the anti-freeze to the level of max on the expansion tank.
