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

A primary symptom of a failing fuel shut-down solenoid is the engine's inability to start because fuel cannot reach the injection system. Alternatively, it may fail to shut off when the ignition is turned off, causing the engine to continue running. Erratic engine behavior, such as stalling or surging, can also occur if the solenoid is intermittently failing.

Installation Tip

Ensure the electrical connection is clean and secure, as a poor connection can mimic a faulty solenoid. Do not force the solenoid into its fitting; it should thread in smoothly.

Service Note

Inspect the fuel filter and fuel lines for any blockages or contamination when replacing the shut-down solenoid valve.
