The coolant level must be checked before each trip. Check the fluid level on a cold engine
The expansion tank has maximum and minimum level marks.
When the engine has cooled down, the fluid level should be slightly above the maximum.
If the level is below the minimum mark, then add fluid to the expansion tank.
Unscrew the cap of the expansion tank and add fluid
If the engine is hot, do not immediately unscrew the expansion tank cap.
You need to wait until the engine cools down a little, and then unscrew the plug a quarter of a turn, releasing the pressure in the cooling system.
It is recommended to replace the fluid in the cooling system after 75 thousand km of vehicle mileage.
But if the fluid is very dirty, you need to replace the fluid and flush the cooling system with water.
Replacing coolant
We prepare the car for the job.
We install the car on a lift or inspection hole.
Move the air temperature regulator handle in the heating system control unit to the red sector of the scale.
For work you will need: a container for draining the coolant, preferably a basin, new coolant, rags, a 13mm wrench or a 13mm socket with a wrench.
To drain the coolant, remove the middle mudguard, Figure 4.
We place a container to drain the liquid and unscrew the plastic drain plug in the radiator
Drain the coolant
To allow fluid to flow out of the system faster, open the cap on the expansion tank.
After this, drain the coolant from the engine block
Use a 13mm wrench or socket to unscrew the drain plug, placing a container for drainage
Drain the liquid from the engine block jacket
After this, it is advisable to flush the system with water.
Tighten the drain plugs on the radiator and engine block.
The engine drain plug has a tapered thread, so you need to tighten the plug until the rotation resistance sharply increases.
We fill the cooling system with liquid through the expansion tank.
Start the engine and, as the coolant level in the expansion tank drops, bring it to normal and tighten the tank cap.
Checking the operation of the cooling system.
When the engine heats up, the lower radiator hose The meat should be cold and then warm up quickly.
This indicates that the thermostat valve has activated and the liquid has begun to circulate in a large circle.
Wait until the engine cooling fan comes on.
In the cold season, you can use the gas pedal to increase engine speed to quickly warm up the engine.
In the cabin, we check the operation of the interior heater.
Check the fluid level in the expansion tank.
