    VACUUM DIAGRAMS

    Print

    Following are vacuum diagrams for most of the engine and emissions package combinations covered by this guide. Because vacuum circuits will vary based on various engine and vehicle options, always refer first to the underhood Vehicle Emission Control Information (VECI) label, if present. Should the label be missing, or should the vehicle be equipped with a different engine from the vehicle's original equipment, refer to the following diagrams for the same or similar configuration.

    If you wish to obtain a replacement emissions label, most manufacturers make the labels available for purchase. The labels can usually be ordered from a local dealer.
