DIAGNOSTIC STRATEGY AND QUICK CHECKLIST

• Start with a scan: If the Check Engine Light is on, retrieve codes to identify the system (ignition, fuel, exhaust, or sensor).
• Inspect for leaks: Look under the engine for oil, coolant, or ATF leaks; note location and drip pattern.
• Inspect ignition and fuel: Check spark plugs, coils, fuel pressure (if you have the tools or a shop can test), and injector operation.
• Transmission health: Check ATF level and color; note for burnt smell or foaming; monitor shifting behavior.
• Brakes and suspension: Listen for creaks or grinding; check pad wear and rotor surface; inspect ball joints, tie rods, and wheel bearings.
• Cooling system: Check coolant level and condition; inspect hoses for cracks; verify radiator for leaks and fans for proper operation.
• Electricals: Test battery and alternator; inspect fuses and grounds; check for parasitic draw if unexplained battery drain occurs.
• Visual rust inspection: Inspect frame rails and suspension mounting points, especially if you live in snow-prone or coastal regions.

POINTERS FOR OWNERS AND USED-TRUCK BUYERS

• When buying used (2004–2008 F-150): Look for signs of heavy towing, overheating episodes, and consistent maintenance records. Inspect the frame for rust, test drive to assess shifting and braking quality, and check service history for transmission/heater/cooling work.
• Maintain a proactive schedule: oil changes every 5,000–7,500 miles (or as recommended by the owner’s manual), ATF change if indicated by service history, coolant/thermostat checks, and inspect ignition components on schedule.
• Beware of regional issues: In areas with heavy road salt or humid climates, frame and underbody rust are more likely; check those areas carefully.
