Visual/Physical Engine Compartment Inspection

VISUAL/PHYSICAL ENGINE COMPARTMENT INSPECTION


Perform a careful visual and physical engine compartment inspection when performing any diagnostic procedure or diagnosing the cause of an emission test failure. This can often lead to repairing a problem without further steps. Use the following guidelines when performing a visual/physical inspection:
^ Inspect all vacuum hoses for punches, cuts, disconnects, and correct routing.
^ Inspect hoses that are difficult to see behind other components.
^ Inspect all wires in the engine compartment for proper connections, burned or chafed spots, pinched wires, contact with sharp edges or contact with hot exhaust manifolds or pipes.
