Radiator cap
1 - overpressure valve - opens at 81,4-108 kPa;
2 - a cover of a radiator; | 3 - spring;
4 - spring vacuum valve; the vacuum valve opens at minus 6.86 kPa vacuum. |
Checking the overpressure valve
| PERFORMANCE ORDER | | 1. Remove all foreign bodies from the valve seat and valve radiator cap. |  | 2. Attach the radiator cap on the test instrument to test the radiator cap. Create a pressure of 81.4 kPa. The opening pressure of the overpressure valve: 81,4-108 kPa
Minimum opening pressure of the overpressure valve: minus 6.86 kPa | | 3. After 10 to check the pressure, which should not change. | | 4. If necessary, replace the radiator cap. |

The valve of the vacuum valve
| PERFORMANCE ORDER |  | 1. Check for damage of the spring and the mating surfaces of the valve. | | 2. pull back pressure valve to open it. Make sure that when you release the valve is fully closed. Attach the radiator cap on the test instrument to test the radiator cap. | | 3. Create a vacuum, until it is stabilized. | | 4. After 10 to check the pressure, which should not change. |
