Procedure

1. 1

   Remove front engine accessories and crankshaft pulley
   Remove drive belt by rotating tensioner counterclockwise. Remove alternator and A/C compressor with lines attached, securing them aside. Using harmonic balancer puller, remove crankshaft pulley bolt (requires impact wrench or breaker bar with crankshaft holding tool). Remove crankshaft pulley from crankshaft.
2. 2

   Remove right-side motor mount
   Support engine weight with support fixture or hoist. Remove right-side engine mount bolts starting with upper bracket mounting bolts, then through-bolt. Remove motor mount assembly completely. This provides access to timing cover.

3. 3

   Remove timing chain cover
   Remove all timing cover bolts noting different lengths and locations. There are multiple bolt sizes; 8mm bolts require specific sequence on reassembly. Carefully pry timing cover away from engine block using plastic pry points. Clean all RTV residue from cover and block mating surfaces using scraper and brake cleaner.
   ⚠Do not damage aluminum timing cover surface. Scratches or gouges will cause oil leaks.
   Torque spec

   Cover Bolts16 Nm (12 lb-ft)
4. 4

   Mark and verify timing chain alignment
   Rotate crankshaft to TDC on cylinder #1 (crankshaft keyway at 12 o'clock, camshaft timing marks aligned with head surface). Use paint marker or scribe to mark timing chain links to camshaft and crankshaft sprockets. Photograph alignment for reference. Verify both intake and exhaust camshaft marks are properly aligned before proceeding.
   ⚠️Incorrect timing marks will result in valve-to-piston contact and engine destruction. Verify multiple times before proceeding.
5. 5

   Remove timing chain tensioner and guides
   Remove timing chain tensioner by pushing in plunger and inserting retaining pin to lock it. Remove tensioner mounting bolts. Remove timing chain guide bolts and guides. Keep all hardware organized by location for proper reassembly.
6. 6

   Remove timing chain and crankshaft sprocket
   Slide timing chain off camshaft sprockets while supporting chain. Remove chain completely from engine. Remove crankshaft timing sprocket by pulling straight off crankshaft. Inspect sprocket teeth for wear or damage.
7. 7

   Remove oil pan
   Remove all oil pan bolts in crisscross pattern working from outside to center. Carefully separate oil pan from block using RTV cutting tool or thin gasket scraper. Clean all RTV residue from oil pan and engine block mating surfaces thoroughly. Inspect oil pan for damage or warpage.
   ⚠Oil pan is aluminum and easily damaged. Do not use excessive force or metal pry tools on pan flange.
   Torque spec

   Oil Pan Bolts12 Nm (9 lb-ft)
8. 8

   Remove oil pump pickup tube
   Remove oil pump pickup tube mounting bolts securing strainer to pump body and support bracket. Remove pickup tube and strainer assembly. Inspect strainer screen for debris or damage. Clean strainer thoroughly if reusing.
   Torque spec

   Oil Pump Pickup Tube12 Nm (9 lb-ft)
9. 9

   Remove oil pump assembly
   Remove all oil pump mounting bolts from front of engine block. There are typically 8-10 bolts of varying lengths. Note bolt positions for reinstallation. Carefully pry oil pump assembly away from block using plastic pry points. Remove oil pump O-ring from block groove.
   ℹ️Oil pump drives directly from crankshaft. Ensure crankshaft drive flats are clean and undamaged.

10. 10

    Inspect and prepare new oil pump
    Clean crankshaft oil pump drive surface thoroughly with brake cleaner. Inspect crankshaft drive flats for wear or damage. Install new O-ring on oil pump body, lubricating with clean engine oil. Verify new pump rotates freely by hand. Pack oil pump with petroleum jelly to prime before installation.
    ℹ️Priming oil pump with petroleum jelly ensures immediate oil pressure on startup and prevents dry running.
11. 11

    Install new oil pump
    Align oil pump with crankshaft drive flats and carefully slide pump onto crankshaft. Ensure O-ring seats properly in block groove. Install all oil pump mounting bolts finger-tight, then torque in crisscross pattern to specification. Verify pump rotates with crankshaft when turned by hand.

12. 12

    Install oil pump pickup tube
    Install new pickup tube O-ring if equipped. Position oil pump pickup tube and strainer onto oil pump body and support bracket. Install mounting bolts and torque to specification. Verify pickup tube is properly seated and clearance to oil pan is adequate.

13. 13

    Install oil pan with new gasket
    Clean all mating surfaces completely. Apply thin continuous bead of Toyota RTV sealant to oil pan flange (3mm bead). Install oil pan within 15 minutes of RTV application. Install all oil pan bolts finger-tight, then torque in crisscross pattern from center outward to specification. Allow RTV to cure for 2 hours before filling with oil.
    ⚠Excessive RTV can break off and clog oil pickup screen. Use only specified amount in continuous bead.

14. 14

    Reinstall timing chain and components
    Install crankshaft timing sprocket onto crankshaft with timing mark facing out. Position timing chain onto crankshaft sprocket first, then wrap around camshaft sprockets while aligning all timing marks precisely with marks made during disassembly. Install chain guides and secure with bolts. Install timing chain tensioner with plunger locked, then remove retaining pin to apply tension. Rotate crankshaft two complete revolutions and verify all timing marks realign perfectly at TDC.
    ⚠️Verify timing alignment by rotating engine two full revolutions by hand. All marks must realign or valve damage will occur.
15. 15

    Install timing cover with new gasket and seal
    Install new crankshaft front seal into timing cover using seal driver. Apply thin bead of Toyota RTV sealant to timing cover mating surface where specified (typically at block-to-head junction points). Position new timing cover gasket and install cover onto block. Install all timing cover bolts finger-tight, ensuring proper bolt lengths in correct locations. Torque 8mm bolts in specified sequence, then torque remaining cover bolts to specification.
    ⚠Timing cover bolt sequence is critical to prevent warpage and oil leaks. Follow factory sequence precisely.

16. 16

    Reinstall motor mount and accessories
    Install right-side motor mount assembly and torque mounting bolts to specification. Remove engine support fixture. Install crankshaft pulley onto crankshaft, torque pulley bolt to specification (typically 133 Nm but verify). Install A/C compressor and alternator with mounting bolts torqued to specification. Install drive belt and verify proper routing.

    Complete final assembly and fill fluids
    Install new oil drain plug crush washer and torque drain plug to specification. Install new oil filter and pre-fill with fresh oil. Fill engine with 5.0 quarts Toyota Genuine 0W-20 oil. Refill cooling system with Toyota Super Long Life Coolant. Reinstall inner fender liner and wheel. Lower vehicle and install engine cover. Reconnect battery negative cable.
    Torque spec

    Oil Drain Plug35 Nm (26 lb-ft)

Reassembly

1. Ensure all timing marks are precisely aligned before starting engine
2. Allow RTV sealant to cure for minimum 2 hours before starting engine
3. Double-check all bolt torques, especially timing cover bolts and oil pan bolts
4. Verify oil drain plug has new crush washer installed
5. Confirm oil filter is properly tightened and no old gasket remains on block

Verification

• Start engine and immediately verify oil pressure light extinguishes within 2-3 seconds
• Listen for any abnormal timing chain noise or rattling during initial startup
• Allow engine to reach operating temperature and verify no oil leaks from pan, pump, or timing cover
• Check for coolant leaks around timing cover area
• Monitor oil pressure gauge (if equipped) to verify normal pressure readings (20-80 psi depending on RPM)
• After 20 minutes of running, shut off engine, wait 5 minutes, and recheck oil level; top off if needed
• Test drive vehicle and verify normal operation with no warning lights
• After first 100 miles, recheck oil level and inspect underneath for any leaks
