Procedures

Lubrication to prevent seizing
Screw connections exerted to considerable changes in temperature tend to seize making it difficult to loosen them at the next service.

Examples of such screw connections:

Oxygen sensor

Exhaust manifold and turbo unit nuts

Recommended lubricant: 90 513 210 Universal paste or NEVER SEIZE.
