3.5L Engine Complete Assembly with 2-Piece Oil Pan for 2018 Ford & Lincoln

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

• Verify the 8th digit of the VIN is G (Raptor) or T (Navigator).
• Verify the vehicle build date on the door jamb sticker is on or before February 25, 2018.
• Physically inspect the oil pan to confirm it is a two-piece design (plastic/composite lower pan mated to an aluminum/steel upper section).
• Confirm the vehicle is equipped with an automatic transmission.

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

Special tools this job needs:

• Steck Ford 3.5L/3.7L EcoBoost Engine Out Lift Plate Hoist Tool (Part #50133)
• Camshaft holding/alignment timing tool kit (OTC 303-1655 / 303-1656)
• Torx Plus TP55 socket
• Inverted Torx sockets (e.g., E7)
• Crankshaft pulley/harmonic balancer puller
• High-pressure fuel line disconnect tools
• Bi-directional diagnostic scan tool (Ford IDS/FDRS or FORScan)

Budget for these consumables at install:

• 6.0 quarts of premium OE-spec 5W-30 full synthetic motor oil
• Motorcraft FL-500S oil filter
• Motorcraft Orange or Yellow pre-diluted engine coolant (WSS-M97B57-A1 or WSS-M97B51-A1)
• Upper and lower intake manifold gaskets
• Valve cover gaskets
• Exhaust manifold gaskets and turbocharger mounting gaskets/hardware
• High-pressure fuel pump O-ring
• One-Time-Use High-Pressure Fuel Line (Ford Part #HL3Z-9J323-C)
• 6 OE-spec spark plugs (gapped to 0.030 inches)
• Motorcraft TA-357 High-Performance Engine RTV Silicone
• Torque-to-yield bolts (crankshaft pulley bolt, cam phaser bolts)

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

What’s involved: Crankshaft Position (CKP) Sensor Relearn, Fuel Injector Calibration (IQA Codes), and PATS Parameter Reset

Requires a Parameter Reset to marry the PCM and PATS immobilizer system to prevent a no-start condition. Additionally, CKP sensor relearn and programming of the 30-digit fuel injector calibration codes are required. Sources differ on whether programming is strictly model-dependent or universally required; choosing 'model_dependent' as the more cautious value.

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

• Turbocharger Oil Feed Line Replacement: Must replace lines and block fittings containing mesh screens to prevent oil starvation and immediate turbo failure.
• High-Pressure Fuel Line Trap: The metal fuel line is single-use only. Reusing it will cause a high-pressure fuel leak and severe fire hazard.
• Two-Piece Oil Pan Inspection: Highly prone to warping and leaking. Resealing requires meticulous cleaning and a 24-hour RTV cure time. Upgrading to a one-piece aluminum pan is highly recommended while the engine is out.
• Pre-Install Cam Phaser Inspection: Inspect and replace worn phasers on the stand to avoid a grueling 10+ hour job inside the vehicle later.
• Cab-Off Installation: Many professional shops lift the vehicle's cab off the frame to access the engine due to tight clearances.

Easy to get right once you know them:

• Reusing the single-use high-pressure fuel line, leading to fuel leaks and engine fires.
• Reusing clogged turbo oil feed lines, causing immediate failure of transferred turbochargers.
• Rushing the RTV cure time on the oil pan, resulting in immediate and persistent oil leaks.
• Ordering this High-Output engine as an upgrade for a standard 3.5L EcoBoost vehicle (VIN 4).
• Skipping the mandatory Crankshaft Position Relearn or PATS programming, resulting in rough running or a no-start condition.
