1. Remove the old drain plug. Clean the oil pan thread and face area with a clean cloth.

2. Inspect the SMART-O® O-ring. Ensure the O-ring is seated correctly in the groove. Do not apply thread sealant or PTFE tape.

3. Thread by hand first. Always start threading by hand to avoid cross-threading. Thread until the plug head contacts the oil pan face.

4. Tighten with SmarTorq™. Petrol engines: 24.4 Nm (18 ft-lb). Diesel engines: 40.6 Nm (30 ft-lb). Do not exceed these torque values.

5. Check after first run. After the first run, inspect for leaks. The O-ring expands slightly in contact with engine oil to support seal integrity.

Use the fitment check as a starting point, then confirm thread size before ordering if anything is unclear.
