Before installation, ensure the mounting surface on the engine block is clean and free of debris or remnants from the previous filter gasket. Applying a thin film of clean oil to the new filter's gasket helps create a proper seal and prevents damage during tightening. When installing, hand-tighten the filter until the gasket contacts the mounting surface, then tighten an additional three-quarters of a turn using a filter wrench—avoid over-tightening, which can damage the gasket and make removal difficult 6.
For optimal performance, the oil filter should be changed along with the engine oil at recommended intervals. Even with the extended service capability of the 85372, following the vehicle manufacturer's recommended maintenance schedule is essential. When changing the filter, properly dispose of the used oil and filter according to local regulations. Many automotive retailers offer recycling services for these materials, preventing environmental contamination. Always use the correct oil type and viscosity recommended for your specific engine to ensure compatibility with the filter's design specifications 6,9.
Safety precautions during installation include working on a cool engine to prevent burns and ensuring the vehicle is securely supported if raised. Placing a drain pan beneath the filter during removal will catch any residual oil, and wearing protective gloves prevents skin irritation from used oil. After installation, start the engine and check for leaks around the filter gasket, tightening slightly if necessary. Monitoring oil pressure indicators on the dashboard can confirm proper oil circulation following the filter change 8,9.
