Installation Guide

1. Locate the cabin filter housing in the truck’s driver compartment. Refer to the vehicle’s service manual for exact location if necessary.
2. Open the housing by releasing the latch or removing screws, depending on the model.
3. Remove the old filter carefully, noting its orientation and any markings that indicate airflow direction.
4. Insert the new CU 3861 filter into the housing, aligning it with the airflow arrows. Ensure a snug fit to prevent gaps.
5. Secure the housing cover or screws, then close the latch.
6. Check for proper operation of the HVAC system and verify that no air leaks are present.

Maintenance Tips

• Inspect the filter every 12 months or after heavy exposure to dusty environments. Replace if it appears visibly dirty or clogged.
• Avoid forcing airflow through a severely clogged filter, as this can damage HVAC components.
• Store spare filters in a dry, dust‑free environment to preserve their integrity until use.
