Ford Focus 2.0L L4 Remanufactured Engine 12782E 2005-2007

Description

Experience sharp throttle response with this precision remanufactured Ford Focus 2.0L Duratec Remanufactured Engine. Production machine centers align-hone aluminum block casting 4M5G-FF to restore crankshaft bearing centerline roundness within the engine bay envelope. This 2.0L 4-Cylinder 16-Valve DOHC powerplant requires thorough manual oil circuit priming prior to initial ignition fire to protect dual overhead camshaft saddles from scuffing.

Die-cast aluminum block casting 4M5G-FF features cast iron dry cylinder sleeves and an align-honed crankcase bedplate. A forged steel crankshaft casting 1S7G-CF spins on precision tri-metal main and rod bearings clearanced to 0.0012in. Aluminum DOHC cylinder heads house sixteen valves actuated by mechanical bucket tappets without shims. Crated long block weight measures 252 lbs with crated envelope dimensions of 36in length by 36in width by 36in height and holds 4.5 quarts oil.

Key Features of Ford Focus 2.0L

Automotive repair facilities buy Ford Focus 2.0L remanufactured engine assemblies to restore commuter fuel efficiency and eliminate bottom-end knocking. Technicians install this remanufactured 2.0L long block replacement to end diagnostic check engine lights.

• Aluminum block casting 4M5G-FF receives precision CNC deck milling to secure multi-layer steel cylinder head gaskets.
• Crankshaft casting 1S7G-CF undergoes micro-polishing down to 0.0003in runout to eliminate bearing friction under load.
• Plateau-honed cast iron cylinder liners receive diamond crosshatch finishing to seat replacement piston rings within 500 miles.
• Aluminum cylinder head castings receive CNC valve seat cutting to maintain 0.001in valve seat runout.
• Tri-metal rod bearings maintain 0.0012in oil clearance to protect crankshaft journals under highway loads.
• Shimless mechanical bucket lifters receive micrometer sorting to establish exact factory valve lash tolerances.
• Threaded brass oil gallery plugs replace press-fit plugs to eliminate internal crankcase oil leaks.

Dyno Load Precision Machining Tolerances

Dynamometer testing confirms 136 HP at 6,000 RPM alongside 136 ft-lbs shaft torque at 4,250 RPM on our computer testing cell. Machine shop technicians measure crankshaft journal runout below 0.0003in TIR while rod bearing oil clearance measures 0.0012in. CNC plateau bore honing holds piston-to-bore clearance at 0.0011in to prevent cold piston slap. Operating engine oil pressure sustains 55 PSI at 3,000 RPM with engine coolant stabilized at 192°F. Mechanical cylinder pressure gauges confirm balanced compression between 180 PSI and 185 PSI across all four cylinders.

Vehicle Fitment Drivetrain Guide

This remanufactured engine fits 2005 to 2007 Ford Focus models equipped with the 2.0L 1999cc Duratec 20 engine, VIN Code N, and block casting 4M5G-FF or 1S7G-BX. It mates with 5-Speed Manual or 4-Speed Automatic front-wheel-drive transaxles. This long block does not fit earlier 2.0L Zetec or SPI split-port engines, 2.3L Duratec Focus ST models, modern 2.0L direct-injected Ti-VCT platforms, or Ford Escape SUV configurations.

Installation Protocol Service Requirements

Inspect intake manifold swirl flap runner controls and replace deteriorated rubber passenger-side hydraulic motor mounts prior to installation. Never run this naturally aspirated commuter long block in high-boost turbo packages or custom track carts lacking external oil coolers. Technicians must clean intake ports to eliminate abrasive carbon particulates before starter rotation.

• Pressure-prime internal oil passages with 5W-20 motor oil before initial start to protect camshaft bearing saddles.
• Drain break-in motor oil and swap the spin-on oil filter at 500 miles.
• Inspect serpentine belt tracking and check intake manifold runner actuators at 3,000 miles.
