Rules For Cleanliness

Rules for cleanliness
When working on the exhaust gas turbocharger, pay careful attention to the 5 rules:
^ Thoroughly clean all unions and the adjacent areas before disconnecting.
^ Place removed parts on a clean surface and cover. Use lint-free cloths.
^ Carefully cover or seal open components if repairs cannot be carried out immediately.
^ Only install clean components: Only remove replacement parts from packaging immediately prior to installation. Do not use parts that have been stored loose (e.g. in tool boxes etc.).
^ When the system is open: Do not work with compressed air if this can be avoided. Do not move vehicle unless absolutely necessary.
