Installation & Application Notes

Disconnect main battery before working on electrical components. Use dielectric grease on all connector pins. Check ground connections — most electrical faults trace to poor grounds. Test with multimeter before installing new parts.

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

Failure Symptoms

An initial symptom of a failing liquid level probe might be an inaccurate or absent fluid level reading on the operator's display. If the issue persists, the system may trigger a low fluid level warning, even if the fluid is adequate. Ignoring a faulty probe can lead to operating the machine with dangerously low fluid levels, potentially causing component damage.

Installation Tip

Ensure the mounting surface is clean and free of any debris or old sealant to guarantee a proper seal. Do not overtighten the probe, as this can damage the threads or the housing.

Service Note

When replacing the liquid level probe, inspect the associated wiring and connectors for any signs of corrosion or damage.
