2023 Ford F-150 Raptor
Reliability tier: verified - see /disclosure/
Engine: 3.5L V6 EcoBoost High-Output (Ford EcoBoost, 3.5L)
High-output 3.5L EcoBoost: 450 hp @ 5,000 / 510 lb-ft @ 3,500, paired with the 10R80. Raptor-specific calibration, intakes and cooling on the off-road chassis (Fox suspension hardware - outside the engine platform scope). Raptor R (MY2023+) carries the 5.2L supercharged Carnivore V8 - separate engine, out of this platform (STRATEGY/18 R3).
Applicable failure modes (6)
- Cam phaser / VCT rattle and cam-timing DTCs
- Cooling service: thermostats, hoses, degas system under tow load
- Internal mechanical failures / long-block decisions
- Low-pressure fuel delivery (in-tank pump / pressure faults)
- Ignition misfires: spark plugs and COP coils
- Turbo / wastegate / boost-control faults
Applicable parts (7)
- 3.5L EcoBoost Cam Phaser / Timing Actuator (AT4Z-6256-B)
- Cooling system refill with fresh coolant (service item, all 3.5L EcoBoost applications)
- In-tank fuel filter service (integral to the pump module, all 3.5L EcoBoost applications)
- Cylinder head / block machining and SSM calibration updates (service item, long-block decisions)
- HPFP failure contamination procedure - flush, rails, injector inspection (service item)
- Engine oil and filter change (service item, all 3.5L EcoBoost applications)
- 3.5L EcoBoost Timing Chain (AT4Z-6268-C)
Platform recipes (5)
- CAC-condensation shudder fix: the Gen1 pattern (humid-day single shudder after light-throttle cruising) traces to pooled condensate in the charge-air cooler
- Ignition service for the boost-stressed 3.5L EcoBoost: misfire DTCs first, then plugs and the failed coil(s)
- Cam-phaser rattle / timing-chain service: the cold-start rattle and cam-timing DTCs (P0011/P0015-P0019/P0365/P0369) span generations - Gen2 got formal TSBs (20-2191/20-2166/20-2315) and the 21N08/21B10-S1 PCM-reprogram field actions; Gen1 carries the chain-wear story (TSB 17-0026)
- Turbo / boost-control service: boost DTCs (P0236/P0238/P0299 family) first, hardware second
- Internal water-pump service: the 3.5L EcoBoost carries the pump inside the front cover - a failed seal can send coolant into the oil pan (bearing damage) or leak externally
