Secondary air system

WARNING: When doing any repair work, especially in the engine compartment, pay attention to the following due to the cramped conditions:
^ Route all the various lines (e.g. for fuel, hydraulics, EVAP system, coolant, refrigerant, brake fluid and vacuum lines and hoses) and electrical wiring so that the original positions are restored.
^ Ensure sufficient clearance to all moving or hot components.
