2.5L DOHC iVCT Hybrid Engine Complete Assembly for 2020-2025 Ford Escape, Maverick

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

• Confirm the 8th digit of the VIN is '3' (Maverick Hybrid), 'Z' (Escape Hybrid), or '1' (Escape PHEV).
• Verify the vehicle is a front-wheel drive (FWD) or all-wheel drive (AWD) hybrid configuration matching the closed application list.

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

Special tools this job needs:

• High-voltage insulated safety gloves (Class 0, rated for 1,000V AC)
• Ford FDRS (Ford Diagnosis and Repair System) scan tool with J2534 pass-thru device
• Engine support bar or hoist
• Crankshaft timing peg and alignment tools

Budget for these consumables at install:

• 5.7 quarts of premium full synthetic 0W-20 motor oil meeting Ford specification WSS-M2C962-A1
• Motorcraft FL-910S (or equivalent) oil filter
• Motorcraft Yellow Prediluted Antifreeze/Coolant meeting Ford specification WSS-M97B57-A2 (High-Temp Circuit: ~9.6 quarts; Low-Temp Circuit: ~5.0 quarts)
• New OE-spec spark plugs (gapped to 0.049–0.053 in / 1.25–1.35 mm)
• New intake manifold gaskets, exhaust manifold gasket, and water outlet gaskets
• New torque-to-yield (TTY) bolts (crankshaft pulley/harmonic balancer bolt and flexplate bolts)

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

What’s involved: PCM reprogramming, Crankshaft Position (CKP) sensor profile correction/relearn, and clearing of hybrid system diagnostic trouble codes (DTCs)

A Ford dealer-level scan tool (FDRS) is required to perform the CKP relearn, initialize the hybrid powertrain control module (HPCM), and perform any necessary PCM software updates.

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

• Keyless Crankshaft Timing: The crankshaft pulley/harmonic balancer does not have a keyway. Loosening the bolt without the proper timing peg and alignment tools will cause the engine to drop out of timing, leading to catastrophic valve-to-piston contact.
• High-Voltage Disconnect: Must safely depower the high-voltage hybrid battery system by removing the High-Voltage Service Disconnect plug and waiting at least 10 minutes before verifying zero voltage.
• Dual Cooling Loops: The hybrid system features separate engine high-temperature and inverter low-temperature loops. Both must be vacuum-filled and bled using a scan tool to activate the electric water pumps to prevent immediate inverter overheating.
• Cylinder Head Temperature (CHT) Sensor: Highly prone to damage during the swap process; Ford recommends replacing it before installing the engine appearance cover.

Easy to get right once you know them:

• Reusing Torque-to-Yield (TTY) Bolts: Reusing the crankshaft pulley bolt or flexplate bolts can lead to the pulley slipping or the flexplate backing off, causing severe engine damage.
• Using the Wrong Coolant: Adding standard green or orange coolant instead of Motorcraft Yellow coolant (WSS-M97B57-A2) can cause gel formation and clog the hybrid inverter heat exchanger.
• Failing to Perform the Crankshaft Position (CKP) Relearn: Leads to poor running, shaking, or misfire codes (like P0300) post-install.
• Damaging the A/C Lines: Tight engine bay packaging makes it easy to bend or crack the aluminum A/C lines when maneuvering the engine.
• Ignoring the VIN Code: Ordering this engine for a vehicle with a different 8th VIN digit (such as '9' for the 2.0L EcoBoost or earlier hybrid generations).
