Procedure

1. 1

   Disconnect engine accessories and wiring
   Disconnect all electrical connectors from engine including alternator, starter, all sensors (MAF, IAT, coolant temp, oil pressure, knock sensors, CMP, CKP), ignition coils, and fuel injectors. Disconnect throttle body connector and wiring harness clips. Remove engine wiring harness and secure away from engine. Label everything for reassembly.
2. 2

   Remove intake and exhaust systems
   Remove throttle body and intake manifold assembly. Disconnect exhaust system at manifold flanges. Remove both exhaust manifolds from cylinder heads. On 4WD models, may need to lower front differential or remove crossmember for clearance.
3. 3

   Disconnect fuel and cooling systems
   Disconnect fuel supply and return lines at fuel rail (use proper fuel line disconnect tools). Disconnect all coolant hoses including upper and lower radiator hoses, heater hoses, and bypass hoses. Remove thermostat housing if needed for clearance. Cap all open lines to prevent contamination.
4. 4

   Remove accessory drive components
   Remove serpentine belt. Remove power steering pump with lines attached and secure aside. Remove A/C compressor with lines attached and secure aside (do not let hang by hoses). Remove alternator. Remove power steering pump bracket and A/C compressor bracket from engine block.
5. 5

   Separate transmission from engine
   Support transmission with transmission jack. Remove transmission-to-engine bellhousing bolts. If equipped with manual transmission, remove clutch hydraulic line. Carefully separate transmission from engine, ensuring torque converter stays with transmission on automatic models. Lower transmission slightly and secure.

   Remove external components from old engine
   With engine on stand, remove remaining external components: starter, flexplate/flywheel, oil pan, oil pump, timing cover, timing chains, variable cam timing (VCT) components, water pump, cylinder heads with camshafts and valvetrain intact. Keep cylinder heads assembled on stand. Remove rear main seal housing. Clean all mating surfaces thoroughly.
   ⚠Mark timing chain positions and cam phaser orientation before removal for reference during reassembly, even though new block will use same timing procedure.

   Prepare new short block
   Mount new short block on engine stand. Verify all main bearing caps are properly torqued and that crankshaft rotates freely. Check that all block passages are clean and free of debris. Install rear main seal housing with new gasket and seal. Apply engine assembly lube to crankshaft journals and cylinder walls. Install oil pump with new O-ring and proper alignment.
   ℹ️Main bearing caps on new short block should already be torqued from factory, but verify torque sequence and values per specifications.

   Install timing system components
   Install front crankshaft seal into timing cover. Install timing cover with new gasket, ensuring proper alignment with crankshaft and oil pan rail. Torque timing cover bolts in proper sequence. Install timing chains, guides, tensioners, and VCT phasers per Ford timing procedure, ensuring proper cam timing alignment. Install crankshaft pulley with new bolt (TTY).
   ⚠Timing must be set precisely per factory procedure. Incorrect timing will cause severe engine damage. Verify all timing marks align at TDC.

    Install cylinder heads
    Clean block deck surfaces thoroughly. Install new cylinder head gaskets (do not reuse) with proper orientation. Carefully position cylinder heads onto block. Install cylinder head bolts and torque in proper sequence per Ford specifications (requires multi-step torque-plus-angle procedure). Install valve covers with new gaskets.
    ⚠Cylinder head bolt torque sequence is critical. Follow exact Ford tightening sequence and angle specifications. Head bolts are TTY and must not be reused.

    Install oil pan and remaining lower components
    Clean oil pan and block mating surfaces. Apply thin bead of RTV sealant to oil pan rail and at front cover-to-block joints. Install oil pan with new gasket within 10 minutes of RTV application. Torque oil pan bolts in sequence from center outward. Install new oil drain plug with new crush washer. Install flexplate/flywheel with new TTY bolts in star pattern.
    ℹ️Allow RTV to cure for at least 1 hour before filling with oil. Verify flywheel bolt pattern alignment for automatic transmission torque converter.

Install radiator, cooling fan, and shroud. Fill cooling system with 16 quarts Motorcraft Orange Coolant (50/50 mixture). Install new oil filter and fill with 7.5 quarts Motorcraft 5W-20 oil. Reconnect battery cables (positive first, then negative).
    ℹ️Double-check all electrical connections, especially crankshaft and camshaft position sensors, as these are critical for engine operation.

Reassembly

1. Verify all torque specifications were followed, especially TTY bolts which must not be reused
2. Confirm all electrical connectors are fully seated with locking tabs engaged
3. Check that all hose clamps are tight and properly positioned
4. Verify serpentine belt routing is correct and belt tension is appropriate
5. Ensure no tools or rags are left in engine compartment
6. Reinstall engine cover, skid plates, and any remaining trim pieces

Verification

• Perform visual inspection of entire engine bay for any disconnected hoses, wires, or loose fasteners
• Check oil level on dipstick and verify no leaks at oil pan or drain plug
• Verify coolant level is correct and system is properly bled of air
• Turn engine over by hand (using crankshaft pulley bolt) to ensure no binding or obstruction
• Prime oil system by cranking engine with fuel pump fuse removed and spark plugs out until oil pressure gauge shows pressure
• Reinstall spark plugs and fuel pump fuse, then start engine and verify smooth operation
• Check for any fluid leaks while engine runs, particularly at oil pan, timing cover, head gaskets, and rear main seal
• Allow engine to reach operating temperature and verify cooling fan operation and no overheating
• Monitor oil pressure gauge during warm-up to ensure proper pressure
• Check for any abnormal noises such as knocking, ticking, or rattling
• Scan for diagnostic trouble codes and verify no engine-related codes are present
• Perform test drive to verify normal power delivery, transmission shifting, and no warning lights
• Recheck all fluid levels after test drive and inspect for any new leaks
• Allow engine to cool, then retorque cylinder head bolts if required by manufacturer specifications
