Antifreeze is necessary not only for engine cooling and to lubricate the coolant pump. Lubrication is due to the substances contained in the coolant. In addition, the coolant water contains many chemicals which counteract the formation of scale and deposits. But these chemicals have a relatively short period of existence.

So, the manufacturer strongly recommends to replace fluid every 45 thousand kilometers of mileage. In fact, you have to control the acid-alkaline balance in the system. The high content of acids or alkalis can lead to the destruction of the system nodes and to the continued erosion of the walls of the cooling jacket in the engine block. To check the balance by using special indicators.

Preparation for the replacement of antifreeze

The first thing you need to give the engine to cool. Will have to completely drain the old antifreeze from the system, as hot liquid can be very Ambaritsa. And don't forget that the toxicity of antifreeze is very high, therefore it is best to protect hands when working with him. Wear rubber gloves and a respirator.

Now you need to drain the old antifreeze into a container. To do this, remove the motor protection, to provide access to the drain taps on the bottom. Under drain substitute capacity, then only open stub. Don't forget about the stove, it faucet need to open completely to leaked out all the antifreeze.

After draining, close all tube and flush the system with special solutions. To do this, pour into the tank washing liquid, and then start the engine. You need to bring the temperature of the working engine. Do not forget to turn the stove on full power to the system is not a single air bubble.

Replacement of antifreeze

After reaching operating temperature, stop the engine and allow it to cool him. Only after that drain wash fluid. Fill with new antifreeze mixed with water in a ratio of 50/50. Antifreeze can be increased to 70%, but more is not recommended. Close all inlets again start the engine and turn the heater up to full power.

Operate the motor for as long as the antifreeze will not heat up to operating temperature. Be sure to turn on the stove so that the fluid circulated all over the system. It is also recommended to remove the thin hose going to the throttle. Wait until it will be fluid and install in place.
