Section 14 (Vacuum Diagrams): Introduction

WARNING: This page is about a different car, the 2003 Chevrolet Corvette. However, it is still accessible from the selected car via links, so may be relevant.

This article contains underhood views or schematics of vacuum hose routing. Use these vacuum diagrams as a guide during the visual inspection in appropriate BASIC DIAGNOSTIC PROCEDURES article. This will assist in identifying improperly routed vacuum hoses which may cause driveability and/or computer-indicated malfunctions. Always verify vacuum hose routing using underhood emission and vacuum label (if equipped) for specific applications.

NOTE: If underhood vacuum label and diagram in manual differ, underhood label should always take precedent, unless it is suspected of not being correct application.
