3.5L PowerBoost Full Hybrid Engine Complete Assembly for 2021-2023 Ford

A quick look at your own vehicle makes sure the right engine shows up:

• Verify the 8th digit of the VIN is 'D'.
• Confirm the truck is equipped with the 10-speed modular hybrid automatic transmission (10R80-MHT).
• Confirm the presence of 'PowerBoost' badges and the high-voltage battery pack under the truck.
• Check the white barcode label on the original engine's front timing cover or driver-side valve cover for engineering codes ML3E-6007-DA or NL3E-6007-PA.

What the install really takes — plan and budget with confidence:

Special tools this job needs:

• High-Voltage Insulated Gloves (Class 0 rated for at least 1,000V AC)
• Ford FDRS / IDS Diagnostic Scan Tool
• Vacuum Coolant Refiller
• Engine Lift Plate (e.g., Milton STC50133)
• Fuel Injector Puller (e.g., ProMAXX PowerPull)
• 76mm oil filter cap wrench

Budget for these consumables at install:

• 6.0 quarts of SAE 5W-30 Full Synthetic Motor Oil meeting Ford specification WSS-M2C961-A1
• Motorcraft FL-500S Oil Filter
• Motorcraft Yellow Prediluted Antifreeze/Coolant meeting Ford specification WSS-M97B57-A2 (VC-13-G)
• Six Motorcraft SP-589 iridium spark plugs (pre-gapped to 0.030")
• Intake manifold gaskets
• Exhaust manifold gaskets
• Turbocharger Gasket Kit (mounting gaskets, oil feed/drain gaskets, and coolant line O-rings)

What your vehicle’s computers will need after the swap:

What’s involved: Programmable Module Installation (PMI), Parameter Reset, Crankshaft Position (CKP) Relearn, and Transmission Adaptive Strategy Reset

Requires Ford FDRS/IDS scan tool or high-end professional equivalent with J2534 pass-thru capabilities and a subscription to the Ford service portal to perform module alignment, parameter reset, and marry the replacement unit to the vehicle's other modules.

Pro tips for a smooth first start-up — hand them to whoever does the install:

• High-Voltage Service Disconnect (CRITICAL): Locate and remove the high-voltage service disconnect plug under the rear seat. Wait at least 10 minutes to allow capacitors to discharge and verify zero voltage before touching orange cables.
• Dual Cooling Loops: The PowerBoost has separate cooling systems for the engine and the low-temperature hybrid electronics. Both loops must be vacuum-filled to prevent air pockets and component damage.
• Cab-Off vs. Cab-On Swap: Lifting the cab off the frame is highly recommended due to tight clearances and complex hybrid wiring.
• Turbo Line O-Rings: Do not reuse quick-connect coolant and oil line O-rings when transferring existing turbochargers.
• Oil Filter Location: The oil filter is difficult to access once installed; replace it before putting the engine in the truck.

Easy to get right once you know them:

• Ordering for a Non-Hybrid Truck: Assuming standard 3.5L EcoBoost engines are identical to the PowerBoost hybrid engine.
• Reusing Turbo Hardware and Seals: Reusing old turbocharger mounting studs, gaskets, and line seals which leads to leaks.
• Skipping the Vacuum Coolant Fill: Attempting to bleed the cooling system using traditional spill-free funnels, causing inverter overheating.
• Neglecting the High-Voltage Disconnect: Attempting to disconnect engine components with the hybrid battery active, risking electrical damage or injury.
• Ignoring TSBs: Failing to check and address known issues like the heat exchanger coolant leak during the swap.
