Tools Required
Caution: To avoid being burned, do not remove the starter/generator control
module (SGCM) cap while the SGCM is hot. The cooling system will release scalding
fluid and steam under pressure if the SGCM cap is removed while the SGCM is still
hot.
- Follow the steps below in order to remove
the starter/generator control module (SGCM) coolant tank cap.
1.1. | Slowly rotate the cap counterclockwise. |
1.2. | Stop rotating and allow the hissing to stop. |
1.3. | After all the hissing stops, continue turning counterclockwise in order
to remove the cap. |
- Wash the pressure cap sealing surface with water.
- Use the J 24460-01
(1)
with the J 46143
in order to
test the pressure cap.
- Test the pressure cap for the following conditions:
• | Pressure release when the J 24460-01
exceeds the pressure rating of the pressure cap. |
• | Maintain the rated pressure for at least 10 seconds. |
• | Note the rate of pressure loss. |
- Replace the pressure cap under the following conditions:
• | The pressure cap does not release pressure which exceeds the rated pressure
of the cap. |
• | The pressure cap does not hold the rated pressure. |
