The manufacturer recommends replacing the coolant after 90 km or 000 years of operation. Frequency of replacement, which antifreeze to fill You need to understand that in a hot car, the coolant is very hot, you need to be careful not to burn yourself. All actions are recommended to be repeated several times. We open the air vent, slightly open the expansion tank, as soon as the air comes out, we close everything. Then we unscrew the expansion plug, normalize the pressure. To do this, you need to start the car and periodically increase the speed to warm up for 5-10 minutes. The main work in the compartment is completed, it remains to expel the air from the system. add liquid to the level and close the dilator.Once the antifreeze is filled in, you can close the hole with a lid as it fills, air will escape through the vent, after which clean water will flow out, some of which remained in the nozzles after washing.through the expansion tank, we begin to fill the system with antifreeze.put all the hoses in place, fix them with clamps.Filling without air pocketsĪfter flushing the system and drying it as much as possible with distilled water, we proceed to the filling stage: For the fourth time, the water will be almost clean, you can start pouring new antifreeze. To perform this operation, simply lay the hoses loose, heat the machine to the thermostat opening temperature. It is enough to pass 3-4 times with distilled water. When replacing antifreeze, it is recommended to flush the cooling system if the replacement is carried out on time, it is not necessary to use special chemicals. If there is a compressor, you can try to blow the system through this hole (Fig.5). on the hose going to the salon we find the air outlet, remove the casing.

for a more complete drain of the old antifreeze, it is enough to remove the hose going to the thermostat (Fig.

Antifreeze will begin to drain, first we place a drain pan under this place (Fig. Remove the clamp and pull the hose up to remove it.

in the niche that opened after removing the air corrugation, at the bottom of the radiator, we find a thick hose.

unscrew the cover of the expansion tank to relieve excess pressure (Fig.And the other end joins behind the headlight) Only one end of the air filter housing needs to be removed. first of all, we eliminate the corrugation with the tube so that subsequent operations can be carried out more comfortably.
