Installation Guide

Installing the MANN‑FILTER W 940/20 is straightforward, but following these steps ensures optimal performance and prevents leaks.

1. Preparation: Warm up the engine to operating temperature. This reduces oil viscosity and makes removal easier.
2. Drain Excess Oil (Optional): While not always necessary, draining a small amount of oil can help prevent spills during filter removal.
3. Remove Old Filter: Use an appropriate wrench or filter tool to unscrew the existing filter. Be prepared for a small amount of oil to escape.
4. Clean the Mounting Surface: Wipe the old gasket area with a clean rag, removing any debris or old sealant.
5. Apply New Gasket (If Required): Some models may need an additional gasket; check vehicle specifications.
6. Screw in the New Filter: Hand‑tighten the MANN‑FILTER W 940/20 until snug, then give a final quarter turn with a wrench. Avoid overtightening to prevent damage.
7. Check for Leaks: Start the engine and observe the filter area for any signs of oil leakage. Tighten slightly if necessary.
