Installation & Service Notes

Recommended Steps

• Verify the exact OEM number on the original Haldex filter assembly

Why Haldex Filters Matter

1. Oil Cleanliness

The filter captures contamination and wear particles that would otherwise circulate inside the Haldex coupling.

2. Pump Protection

A clean filter helps maintain proper oil flow and reduces unnecessary strain on the Haldex pump.

3. AWD Performance

Proper filtration supports stable hydraulic operation and reliable engagement of the rear axle when needed.

4. Preventive Maintenance

Replacing the filter during scheduled Haldex service helps support long-term operation of the coupling and pump assembly.
