Description
Genuine Freightliner OEM fan clutch solenoid valve (A06-60501-005) for the air-actuated cooling fan systems used on Cascadia, Columbia, Century, Coronado, and M2 Business Class trucks. The 12V normally-closed 3-way pneumatic solenoid regulates air pressure to a Horton-style fan clutch — energized to keep the fan disengaged for fuel economy, de-energized to lock the fan to engine speed when the ECM commands cooling. Replaces Horton S23869, GT Development 5031-01-02, and Automann 173.1124.
Signs You Need a New Fan Clutch Solenoid
- Engine cooling fan runs continuously, hurting fuel economy
- Fan fails to engage and engine overheats under load
- Audible air leak from the solenoid body or its fittings
- Fan engages and disengages erratically
- A/C high-pressure switch commands fan but no response
- Fan-clutch fault codes stored in the ECM
