How to deflate and drain the radiator?

Screws can be used to deflate and prevent water. The following are the specific steps:

Tools needed: a screwdriver and a glass.

1. First, for safety, unscrew the air valve.

2. Unscrew the screw for lowering the air valve counterclockwise with a screwdriver. At this time, you should connect the cups below to prevent the ground from getting wet.

3. When you hear the "prick" sound, it means that you are beginning to deflate. With the deflation, water also flows out.

When the "stinging" sound disappears, we continue to drain water. When there is almost one cup, the deflation is more sufficient.

5. Then screw the screw of the bleeder valve clockwise.

6, tighten the relief valve insurance.

7. In this way, a deflation is completed, and the deflation effect is good.
