Observe rules for cleanliness.

Note:
^ Hoses are secured by clamps or retaining clips.





^ For installing the spring-type clips, assembly tool VAS5024A is recommended.
^ Charge air hoses and lines connections must be free of oil and grease before reinstalling.
^ Do not install hoses with lubricants, moisten hose only with water, if necessary.
