VACUUM DIAGRAMS

Print

Following is a listing of vacuum diagrams for most of the engine and emissions package combinations covered by this manual. Because vacuum circuits will vary based on various engine and vehicle options, always refer first to the vehicle emission control information label. Should the label be missing, or should the vehicle be equipped with a different engine from the original equipment, refer to these diagrams for the same or similar configuration.
