For the long-term and efficient operation of the car systems in which liquids are used, they must be changed periodically. In the technical documentation of the car, the requirements are not always indicated when and what to replace, you must understand that there is a limited life. During the operation of any mechanical system, over time, rubber detection, microparticles of metal chips and other trash are formed. That is why you sometimes have to replace all working fluids. Antifreeze - liquid for the engine cooling system, is no exception. In addition to maintaining the temperature regime at the required level, this type of fluid takes part in heating the radiator system of the salon heating system. When circulating through the system, antifreeze is involved in the lubrication of the parts of the cooling system pump, as well as prevents the formation of rust.
When merging antifreeze from the engine block
Replacement tosola. Or the antifreeze will not be a problem for an ordinary car enthusiast. A liquid is needed in such cases:
- Before replacing the car's radiator.
- With a seasonal replacement of coolant.
- When installing a new thermostat.
This system is carried out in 2 stages, as the fluid is contained in the radiator and in the cooling system of the motor.
How to drain antifreeze from the engine block - step 1
Before pouring a new fluid into the cooling system, you must merge the old one. Let's deal with how antifreeze is merged. To drain the working fluid on most cars in the cooling system, a drain plug is installed. It is installed at the bottom point of the system, on one of the lower angles of the radiator. A drain cork may not be provided on some models of cars. In such cases, to merge the old liquid, it is necessary to disconnect one of the sockets of the cooling system connected to the radiator.
Note, in no case cannot be merged antifreeze on the hot motor. When the fluid is heated, its expansion occurs, which means the pressure inside the system rises. What for? High pressure prevents the evaporation of the fluid in the system. If you are in such a situation, remove the hose or open the drain plug, the system in the system comes with atmospheric, which will result in the formation of a powerful jet of steam.
Only after the engine completely cools can merge liquid. Unscrew the cover located on an expansion tank of the cooling system. Open the drain cork or disconnect the nozzle. Wait until the entire antifreeze is found. Note, a certain amount of fluid is located below the level of the drain hole (the cabin heating radiator). Without a work of additional operations, you will not be able to remove this fluid from the cooling system.
How to drain antifreeze from the engine block - step 2
To merge the residues of the coolant, follow these steps:
- Using the cape key, unscrew the drain plug, which is located under the ignition unit.
- Wait about 10 minutes while antifreeze is alive.
- Wipe the plug, appreciate the state of the seals. If necessary, replace them and tighten the lid.
Note the antifreeze is an active chemical. It has a sweet odor that can attract pets or children! It must be drained into tightly closing tanks. It is strictly not recommended to perform drain just on the ground.
Fill new coolant
Only after the complete drain of the old antifreeze can be attached to the fill of the new one. The manufacturer and brand of substances must comply with the manufacturer's recommendations. The use of additional additives can be negatively affected by the formation of rust in the radiator or the cylinder block.
The level of poured tosola. must be between MIN marks and max on an expansion tank. After replacing antifreeze, air traffic jams can be formed. To get rid of them, you need to loosen the clamp of the pipe. Fill the coolant is needed gently and gradually. After performing all the work, boil the engine and place the level of the stove into the maximum mode. If there is no heat to do, it means you did not get rid of all the air traffic jams, which will cause engine overheating.
