2. 2

   Remove crankshaft pulley and harmonic balancer
   Use crankshaft holding tool to prevent rotation. Remove crankshaft pulley center bolt (reverse threaded on some applications - verify rotation direction). Use harmonic balancer puller to remove balancer from crankshaft snout. Do not use impact tools or pry against balancer. Inspect keyway in crankshaft for damage.
3. 3

   Remove oil pan
   Remove the transmission-to-oil pan bolts if applicable. Support the oil pan and remove all oil pan bolts working from the outside toward the center. Carefully break the RTV seal using a plastic scraper - do not pry between sealing surfaces. Lower oil pan and remove from vehicle. Clean all old RTV from both oil pan and engine block mating surfaces thoroughly.
   ⚠Metal scrapers or prying tools can damage aluminum sealing surfaces. Use only plastic tools on mating surfaces.

4. 4

   Remove timing cover
   Remove all timing cover bolts noting locations as different lengths are used in different positions. There are multiple bolt sizes - separate 8mm bolts from larger bolts. Carefully pry timing cover away from engine block using designated pry points only. Remove and discard timing cover gasket. Clean all gasket material and RTV from timing cover and engine block mating surfaces.
   ℹ️Timing cover bolts are different lengths. Organize bolts by position during removal to ensure correct reinstallation.

5. 5

   Verify and mark timing chain position
   Rotate crankshaft to Top Dead Center (TDC) cylinder #1 compression stroke. Verify timing marks on crankshaft and camshaft sprockets align with timing chain marks. Use paint marker or scribe to mark chain position on sprockets. Take photos for reference. Install timing chain locking tools per Ford service procedure to maintain alignment.
   ⚠️Incorrect timing chain alignment will cause piston-to-valve contact and severe engine damage. Triple-check all alignment marks.
6. 6

   Remove oil pump pickup tube
   Remove the two bolts securing the oil pump pickup tube to the oil pump. Carefully withdraw the pickup tube from the oil pump housing. Inspect the O-ring on the pickup tube and replace during reassembly. Check pickup tube screen for debris or damage.

7. 7

   Remove oil pump
   Remove the four oil pump mounting bolts securing the pump to the engine block. The pump is located behind the timing chain on the front of the crankshaft. Carefully pull the oil pump straight off the crankshaft - it is driven by flats on the crankshaft snout. Inspect crankshaft drive flats for wear or damage.
   ℹ️Oil pump must slide straight off crankshaft without binding. Do not force or cock the pump during removal.

8. 8

   Inspect and prepare new oil pump
   Compare new oil pump to old unit ensuring correct part number. Verify oil pump drive flats align with crankshaft flats. Prime new oil pump by filling with clean engine oil and rotating by hand. Check pump for smooth rotation and no binding. Apply clean engine oil to crankshaft seal area and pump drive gears.
9. 9

   Install new oil pump
   Align oil pump drive flats with crankshaft drive flats. Carefully slide pump onto crankshaft ensuring it seats fully against engine block mounting surface. Install oil pump mounting bolts and tighten evenly in a crossing pattern to specified torque. Verify pump is seated flush with no gaps between pump body and block.

    Install oil pump pickup tube
    Install new O-ring on oil pump pickup tube lubricated with clean engine oil. Insert pickup tube into oil pump housing ensuring O-ring seats properly. Install and torque pickup tube mounting bolts to specification. Verify tube is securely mounted with no movement.

11. 11

    Verify timing alignment and install timing cover
    Remove timing chain locking tools and manually rotate crankshaft two complete revolutions. Recheck timing marks align at TDC - all marks must be precise. Install new timing cover gasket with new front crankshaft seal in place. Apply thin bead of RTV to corners where gasket meets oil pan surface. Position timing cover and install all bolts finger-tight first. Torque 8mm timing cover bolts in sequence specified in service manual from center outward.
    ⚠Timing must be verified after two full crankshaft rotations before proceeding. Any misalignment requires immediate correction.

    Install oil pan
    Clean all mating surfaces on oil pan and engine block completely. Apply continuous 3-4mm bead of RTV silicone (Motorcraft TA-31) to oil pan sealing surface. Install oil pan within 10 minutes of RTV application. Install all oil pan bolts finger-tight, then torque in sequence from center outward to specification. Allow RTV to cure for minimum 30 minutes before filling with oil.
    ℹ️RTV must not cure before oil pan is installed. Work quickly and have all parts ready before applying sealant.

    Install harmonic balancer and crankshaft pulley
    Clean crankshaft snout and verify keyway and key are undamaged. Apply thin coat of clean engine oil to seal contact area on balancer. Install harmonic balancer ensuring keyway aligns properly. Install crankshaft pulley center bolt and use holding tool to torque to specification per Ford service manual (typically 350+ Nm). Install crankshaft pulley.
14. 14

    Reinstall front accessories and cooling system
    Reinstall water pump with new gasket. Reinstall A/C compressor, alternator with bracket, and power steering pump to their mounting positions. Torque all mounting bolts to specification. Reconnect all electrical connectors using labels from disassembly. Install serpentine belt and tensioner. Install radiator, cooling fans, and all coolant hoses. Install new oil filter.

    Fill fluids and perform initial start
    Install oil drain plug with new crush washer and torque to specification. Fill engine with 7.5 quarts of Motorcraft 0W-20 full synthetic oil. Fill cooling system with 16 quarts of Motorcraft orange coolant mixed per specifications. Reconnect battery. Start engine and verify oil pressure builds within 5 seconds. Check for leaks at oil pan, timing cover, and all connections. Allow engine to reach operating temperature and recheck fluid levels. Monitor for any unusual noises or warning lights.
    ⚠️If oil pressure does not build within 5 seconds of starting, immediately shut off engine and investigate. Running without oil pressure will destroy the engine.

Reassembly

1. Reassembly follows reverse order of disassembly with new gaskets and seals throughout
2. All timing marks must be verified multiple times before buttoning up the engine
3. Use only specified RTV sealant (Motorcraft TA-31) on oil pan and timing cover corners
4. Torque all fasteners in proper sequence using specified torque values
5. Allow RTV sealant to cure for 30 minutes minimum before filling with oil

Verification

• Verify oil pressure builds immediately upon startup using gauge or warning light
• Check for oil leaks at oil pan, timing cover, and oil pump pickup tube after initial start
• Check for coolant leaks at water pump and timing cover after reaching operating temperature
• Verify no unusual engine noises such as rattling or knocking that could indicate timing issues
• Test drive vehicle and monitor oil pressure under various load conditions
• Recheck oil level after test drive and top off if necessary
• Inspect under vehicle for any fluid leaks after test drive and overnight park
