Visual Inspection

Visually inspect following component condition and operation:

• Electrical wiring, looking for chafed, stretched, cut or pinched wires. Ensure electrical connectors fit tightly and are not corroded. See ENGINE PERFORMANCE in SYSTEM WIRING DIAGRAMS article in ELECTRICAL.
• Ensure vacuum hoses are properly routed and are not pinched or cut. See appropriate diagram in VACUUM DIAGRAMS article to verify routing and connections (if necessary).
• Air filter element clogging.
• Automatic transmission fluid condition, level and leakage.
• Auxiliary engine components for looseness and installation.
• Battery volage level, corrosion and terminal tightness.
• Drive belt tension and condition.
• Engine oil condition, level and leakage.
• Engine coolant condition, level and leakage.
• Engine oil pressure warning light operation.
• Engine temperature gauge operation.
• Exhaust system for leaks.
• Fuel level and leakage.
• Fuel level gauge operation.
• Fuses blown.
• Inspect air induction system for vacuum leaks.
• MIL operation.
• Tachometer operation (if equipped).
• Throttle cable play and chaffing.
