2. 2

   Remove accessory drive belts and components
   Remove serpentine belt by rotating tensioner counterclockwise. Remove alternator mounting bolts and set alternator aside without disconnecting wiring. Remove A/C compressor mounting bolts and secure compressor to frame without disconnecting refrigerant lines. Remove power steering pump if equipped (most 2018+ models use electric steering).
   Torque spec

   Mounting Bolts47 Nm (35 lb-ft)
3. 3

   Remove right engine mount and crankshaft pulley
   Support engine weight with support bar or hoist. Remove right side engine mount completely. Using crankshaft holding tool, remove crankshaft pulley bolt (left-hand thread pattern - turn clockwise to loosen). Remove crankshaft pulley from crankshaft nose.
4. 4

   Set engine to TDC compression stroke cylinder 1
   Remove spark plug from cylinder 1. Rotate crankshaft clockwise using 19mm socket on crankshaft bolt until timing marks align at TDC. Verify piston is at top of stroke by inserting wooden dowel into spark plug hole. Ensure camshaft timing marks are aligned per factory specifications. Mark timing chain position relative to cam gears with paint marker.
5. 5

   Remove timing chain cover
   Remove all timing chain cover bolts in reverse of tightening sequence (start from outside and work inward). Note bolt locations as they are different lengths. Gently tap cover with rubber mallet to break seal, then carefully remove cover. Do not allow timing chain to move from marked position.
   ⚠Do not rotate crankshaft or camshafts once timing cover is removed. Movement will cause timing misalignment.

6. 6

   Remove oil pan
   Remove all oil pan mounting bolts. Use plastic gasket scraper to carefully separate oil pan from engine block. Remove oil pan and old gasket material. Clean all gasket surfaces thoroughly with solvent and plastic scraper. Ensure no debris falls into crankcase.

   Oil Pan Bolts12 Nm (9 lb-ft)
7. 7

   Remove oil pump pickup tube
   Locate oil pump pickup tube mounting bolts inside oil pan area. Remove bolts securing pickup tube to oil pump. Remove pickup tube and O-ring. Inspect pickup tube screen for debris or damage.
   Torque spec

   Oil Pump Pickup Tube12 Nm (9 lb-ft)
8. 8

   Remove oil pump assembly
   Remove oil pump mounting bolts from front of engine block. These bolts are accessed from the timing chain side. Carefully pry oil pump from engine block using small pry bar at designated pry points. Remove oil pump and O-ring seal. Do not damage crankshaft or engine block surfaces.
   Torque spec

   Oil Pump Bolts12 Nm (9 lb-ft)
9. 9

   Clean all mating surfaces and inspect components
   Thoroughly clean oil pump mounting surface on engine block, timing cover mating surface, and oil pan mating surface. Remove all old gasket material and RTV sealant using plastic scraper and solvent. Inspect crankshaft for scoring or damage. Verify timing chain has not moved from marked position. Clean oil pump pickup tube screen if reusing.
10. 10

    Install new oil pump
    Lubricate new oil pump O-ring with clean engine oil and install on oil pump. Align oil pump drive with crankshaft and carefully install pump onto engine block, ensuring proper engagement with crankshaft drive gear. Install oil pump bolts and tighten to specification in a crisscross pattern.
    ⚠Ensure oil pump drive gear properly engages crankshaft. Improper engagement will cause immediate pump failure.

11. 11

    Install oil pump pickup tube
    Install new O-ring on oil pump pickup tube. Position pickup tube to oil pump and install mounting bolts. Tighten bolts to specification. Verify pickup tube is properly seated and aligned in oil pan area.
    Torque spec

    Oil Pump Pickup Tube12 Nm (9 lb-ft)
12. 12

    Install oil pan with new gasket
    Apply thin bead of Toyota FIPG sealant to oil pan mating surface per factory specifications (typically 2-3mm bead). Position new oil pan gasket. Install oil pan to engine block within 10 minutes of sealant application. Install oil pan bolts and tighten to specification in crisscross pattern from center outward.
    Torque spec

    Oil Pan Bolts12 Nm (9 lb-ft)
13. 13

    Install timing chain cover and new seal
    Install new crankshaft front seal into timing cover using seal driver. Clean timing cover mating surface thoroughly. Apply new timing cover gasket or RTV sealant per factory specifications. Position timing cover carefully over crankshaft nose, ensuring seal does not roll or damage. Install timing cover bolts (note different lengths) and tighten 8mm bolts to specification in proper sequence (typically starting from center and working outward in star pattern).

14. 14

    Reinstall crankshaft pulley and verify timing
    Install crankshaft pulley onto crankshaft nose. Install and tighten crankshaft pulley bolt (remember left-hand thread - turn counterclockwise to tighten) to factory specification. Slowly rotate crankshaft two complete revolutions clockwise and verify timing marks return to TDC alignment. Check paint marks on timing chain match original positions.
15. 15

    Reinstall accessories and complete reassembly
    Reinstall right engine mount and tighten mounting bolts to specification. Reinstall A/C compressor, alternator, and power steering pump (if equipped) with mounting bolts torqued properly. Install serpentine belt per routing diagram. Install new oil filter hand-tight plus 3/4 turn. Reinstall all under covers and splash shields. Reconnect battery negative terminal.

Reassembly

1. Ensure all timing marks are properly aligned before completing reassembly
2. Allow RTV sealant to cure for at least 30 minutes before filling with oil
3. Double-check all bolt torque specifications have been met
4. Verify no tools or parts were left in engine bay

Verification

• Fill engine with 5 quarts of Toyota Genuine 0W-20 engine oil
• Start engine and verify oil pressure light extinguishes within 2-3 seconds
• Allow engine to idle and inspect for oil leaks at oil pan, timing cover, and oil filter
• Listen for unusual noises indicating timing issues or oil pump problems
• Verify no check engine lights or warning messages appear
• After 5 minutes of idle, shut off engine and recheck oil level, adding if necessary
• Road test vehicle and recheck for leaks after engine reaches operating temperature
