How does Sail completely replace antifreeze?

1, wait for 10 minutes after the flameout, and then replace it and fill it up, so as to avoid the antifreeze overflowing and scalding.

2. Press the water tank cover with a cloth and open it gently.

3. Unscrew the drain valve at the bottom of the water tank to drain the old liquid. If there is a drain plug in the engine cylinder, it is necessary to remove the plug and drain the residual coolant in the cylinder.

4. When there is no coolant flowing out, tighten the drain valve and the cylinder body drain plug.

5. Fill the new antifreeze slowly to the highest mark of the water tank.

6. Turn the heater control button to the heating position, start the engine until the radiator outlet pipe becomes hot, and then turn off the engine.

7. Check the liquid level of antifreeze. If the liquid level does not reach the highest mark, it should be replenished.

8. Tighten the water tank cover and cover the machine cover.
