Installation & Application Notes

Never run an engine without a filter — even briefly causes abrasive damage. Pre-fill fuel filters with clean fuel before fitting to reduce prime time. Replace O-rings on filter housings every second service. Record change dates on filter housing.

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 clogged oil filter may initially cause a slight increase in oil pressure or a dimming of the oil pressure warning light. If ignored, the filter's bypass valve will open, allowing unfiltered oil to circulate, leading to accelerated engine wear. This can result in premature engine damage and costly repairs.

Installation Tip

Always lubricate the rubber gasket with clean engine oil before installing the new filter element to ensure a proper seal. Do not overtighten the filter housing, as this can damage the threads or the gasket.

Service Note

When replacing the oil filter element, it is crucial to also replace the engine oil and inspect the oil pan for any debris.
