Personal injury can result from hot oil or hot components. At operating temperature, oil is hot and under pressure. Hot oil can cause burns. Remove the fill cap only when the engine is stopped, and the fill cap is cool enough to touch with your bare hand. Do not allow hot oil or components to contact skin.

1. Install caps and plugs on all openings in order to prevent dirt or debris from entering the system. Cleanliness is an important factor. Before the removal procedure, the exterior of the component should be thoroughly cleaned. This will help to prevent dirt from entering the internal components.

2. Drain the engine oil from the engine. Refer to Operation and Maintenance Manual, "Engine Oil and Filter - Change" for the correct procedure.
