Initial Inspection and Diagnostic Overview



Check routing and condition of all vacuum hoses. SEE Vehicle Emission Control Information (VECI) label, (underhood).

- Ensure all vacuum hoses and electrical wires are routed a minimum of three inches from the exhaust manifold, to prevent deterioration due to high temperatures.

NOTE: Use only fuel resistant hoses when servicing the evaporative control system.
