Vacuum Lines
WARNING: This page is about a different car, the 2005 Chevrolet Optra5 and 2005 Chevrolet Optra. However, it is still accessible from the selected car via links, so may be relevant.
Vacuum lines are molded to a connector, which is attached to a vacuum control switch on the control head assembly.
In case of leakage or hose collapse, it will not be necessary to replace the entire harness assembly. Replacement can be made by cutting the hose and inserting a plastic connector. If an entire hose must be replaced, cut all the hoses off at the connector and attach hoses directly to the control head vacuum switch.
