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 low oil pressure warning light on the dashboard is often the first indication of an oil pump issue. If ignored, the engine may start to make knocking or ticking sounds due to insufficient lubrication. Continued operation without addressing the problem can lead to severe internal engine damage.

Installation Tip

Ensure the oil pump drive gear is properly aligned before installation to prevent damage. Do not overtighten the mounting bolts, as this can distort the pump housing.

Service Note

Inspect the engine oil pan and pickup tube for any obstructions or damage when replacing the oil pump.
