Radiator cap test

1. Use the adapter neck to connect the plug to the instrument.

2. Increase the pressure until the gauge needle stops moving.

• Main valve opening pressure - 78-108 kPa
• Limit value - 65 kPa

3. Check that the pressure is kept at or above the limit.

4. If the pressure gauge reading does not stay at the limit or is higher, replace the radiator cap.
