Wiring for the Coolant Level Switches and the Coolant Level Sensors {7422}
- Engine:
- 3508B (S/N: S2A1-UP; S2B1-UP; S2D1-UP; S2E1-UP; S2F1-UP)
- 3512B (S/N: MRG1-UP; S2G1-UP; MKH1-UP; S2H1-UP; S2J1-UP; S2K1-UP; S2L1-UP; S2M1-UP; S2N1-UP)
- 3516B (S/N: B5G1-UP; PAG1-UP; S2P1-UP; S2R1-UP; S2S1-UP; S2T1-UP; S2W1-UP; S2X1-UP; S2Y1-UP; S2Z1-UP)
The engine can have either switches or sensors in order to monitor the coolant level. The sensors or switches are wired to the "A-C48" customer connector.
The following schematics are for the engines that are listed above.
- Illustration 1 is for the coolant level sensor for the cylinder block (jacket water).
- Illustration 2 is for the coolant level sensor for the Separate Circuit Aftercooler (SCAC).
- Illustration 3 is for the coolant level switches for both the cylinder block and for the SCAC coolant.
