Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

The first indication of a faulty exhaust brake solenoid valve is often the exhaust brake failing to engage or providing significantly reduced braking force. If the issue persists, the system may intermittently fail, or a dashboard warning light related to the exhaust brake could illuminate. Continued operation without a functioning exhaust brake increases wear on the service brakes and reduces vehicle control on descents.

Installation Tip

Ensure the electrical connector is clean and free of corrosion before plugging it into the new solenoid. Avoid using excessive force when tightening the valve mounting bolts, as this can damage the housing.

Service Note

Inspect the exhaust brake actuator and any associated air lines or hydraulic hoses for leaks or damage when replacing the solenoid valve.
