Ford F-150 4.2L V6 Remanufactured Engine 12764E 2004-2007

Description

Experience steady commercial hauling torque by dropping in this Ford Freestar 4.2L Remanufactured Engine long block. Designed for heavy service minivans and light trucks, this 4.2L 6-Cylinder 12-Valve OHV engine solves past lower intake manifold coolant leak issues. A mandatory trade-off requires complete replacement of the intake manifold isolator bolts to prevent vacuum leaks and lean misfires during initial startup.

Cast iron block casting carries identifiers 4F2E-AA, 3F2E-DA, or F65E-AC featuring short main bearing web architecture. Dual intake port cylinder heads carry casting mark YF2E on both left and right cylinder banks. Complete crated envelope dimensions measure 48in length by 48in width by 48in height with an engine weight of 260 lbs. Rotating components include crank casting F65E, forged steel connecting rods, hypereutectic pistons, and a 4.5-quart oil pan.

Key Features of Ford 4.2L

Commercial delivery fleets buy Ford 4.2L remanufactured engine assemblies to restore dependable pulling torque in aging transport vehicles. This dual intake port Essex engine eliminates crankcase coolant contamination and restores balanced cylinder compression.

• CNC deck milling establishes an Ra 30 surface finish to prevent coolant migration through head gaskets
• Cylinder bores undergo diamond plateau honing to seat piston rings and control long-term oil consumption
• Crankshaft casting F65E is precision ground and micro-polished to hold 0.0003in TIR journal runout
• Short main bearing saddles are align-honed to preserve 0.0012in clearance and prevent crank binding
• Pre-installed front timing cover and oil pump maintain precise front crankshaft seal alignment
• Dual intake port cylinder heads receive cut valve seats with 0.001in concentricity for balanced airflow
• New hydraulic roller lifters and hardened pushrods prevent valvetrain tick and maintain valve lift duration

Dyno Load Precision Machining Tolerances

Automated dynamometer spin testing verifies 201 HP output at 4,250 RPM and 263 ft-lbs continuous torque at 3,650 RPM under loaded conditions. Machine shop tolerances enforce crankshaft journal runout below 0.0003in TIR and connecting rod bearing oil clearances at 0.0012in. Plateau-honed cylinder walls deliver compression between 175 PSI and 180 PSI across all 6 combustion chambers. Hot engine oil pressure measures 55 PSI at 2,500 RPM while regulated coolant operating temperatures hold steady at 192°F to verify water jacket flow integrity.

Vehicle Fitment Drivetrain Guide

This remanufactured long block fits 2004 to 2007 Ford Freestar and Mercury Monterey passenger minivans equipped with the 4.2L 256 ci V6 engine and VIN code 2. Matches front-wheel drive transaxles equipped with 4-Speed Automatic 4F50N units. Vehicle application note: this engine features dual intake ports per cylinder and short mains. It does not fit rear-wheel drive Ford F-150 trucks without oil pan, dipstick, and timing cover swaps, nor does it fit 3.8L models.

Installation Protocol Service Schedules

Install new intake manifold gaskets and torque isolator bolts to factory specifications to eliminate unmetered air leaks. Inspect oil cooler passages and flush heater core tubes before turning the ignition key. Never run this non-turbo long block with aftermarket dry nitrous kits exceeding a 50 HP shot without custom ignition timing retard modules.

• Fill crankcase with 4.5 quarts of SAE 5W-20 break-in oil before initial engine startup
• Drain break-in motor oil and change the spin-on oil filter after completing the first 500 miles
• Complete routine synthetic blend oil and filter changes every 3,000 miles or 5,000 miles
