Day 1 & Week 1 Delivery Onboarding Checklist

• Proper cold start routine (3.5L Twin-Turbo EcoBoost V6 Gen-2 PFDI (375 hp / 470 lb-ft, VIN 8th Digit: G)): On the first morning start, let the engine idle for 15–20 seconds until RPM settles before shifting. (Allowing full oil pressure buildup before driving protects timing phasers, lifters, and turbocharger bearings.)
• Smooth transmission engagement (Ford 10R80 10-Speed Automatic Transmission (Electronic Shift)) when parking: Hold the brake pedal firmly, wait until the wheels come to a complete stop, and only then move the gear selector. (Shifting between forward and reverse only at a complete stop protects internal actuators and clutch packs.)
• Cold visual check under the hood (never open pressurized caps hot): With the engine completely cold in the morning, visually inspect translucent reservoirs to confirm levels sit between Min and Max. (Perform dead-cold overnight engine start (oil temp < 70°F) and listen at the front timing cover for 2-to-5 second metallic diesel-like rattle (VCT Cam Phasers — Ford TSB 20-2315).)
