Item | Qty | Part | Specification Description |
1 | 1 | 9X-4730 Flow Switch | Test the flow switch with the paddle (3) in the vertical position and apply force on the rivet head (2). |
Actuation force is |
|||
Minimum deactuation force is |
|||
Contact position is normally open. | |||
- | - | - | When the switch is installed in the engine cooling system, there is not enough force from the flow of coolant at engine cranking speed in order to activate the switch. When the engine is running at low idle, the flow of coolant has enough force in order to activate the switch. |
