Preparation

1. Park vehicle on level surface and engage parking brake
2. Disconnect negative battery terminal and wait 90 seconds for airbag system to discharge
3. Raise and secure front of vehicle on jack stands
4. Remove right front wheel and inner fender liner/splash shield
5. Drain engine oil and coolant into appropriate containers
6. Remove engine oil filter
7. Install engine support fixture across engine bay to support engine weight

Procedure

1. 1

   Remove accessory drive belt and components
   Rotate the drive belt tensioner clockwise and remove the serpentine belt. Remove the drive belt tensioner assembly and alternator if necessary for access. Label and disconnect any electrical connectors as needed.
2. 2

   Remove right engine mount
   Support the engine securely with the engine support fixture. Remove the right engine mount bracket bolts and the mount assembly. This provides access to the timing cover area.

3. 3

   Remove crankshaft pulley
   Install the crankshaft holding tool to prevent rotation. Remove the crankshaft pulley bolt using a breaker bar or impact wrench (bolt is torqued to 133 lb-ft). Remove the harmonic balancer/crankshaft pulley from the crankshaft. Mark the pulley orientation if not keyed.

4. 4

   Remove timing cover bolts and cover
   Remove all timing cover bolts, noting their locations as different length bolts are used. There are both 10mm head bolts (45 Nm) and 8mm head bolts (25 Nm). Also remove the oil pan front section bolts that attach to the timing cover. Carefully separate the timing cover from the engine block. Do not pry against sealing surfaces.

5. 5

   Remove front crankshaft seal
   Using a seal removal tool or seal puller, carefully extract the old front crankshaft seal from the timing cover. Avoid damaging the timing cover bore. Inspect the crankshaft seal surface for grooves or damage that could cause the new seal to leak.
   ⚠Do not scratch or gouge the seal bore in the timing cover or the crankshaft sealing surface, as this will cause oil leaks.
6. 6

   Clean all mating surfaces
   Thoroughly clean all gasket material and old RTV sealant from the timing cover, engine block, and oil pan mating surfaces using a plastic scraper. Clean the crankshaft nose and seal contact area with a lint-free cloth and solvent. Ensure all surfaces are completely dry and free of oil or debris.
7. 7

   Install new front crankshaft seal
   Lightly coat the new seal lip with clean engine oil. Using the appropriate seal installation tool or driver, carefully drive the new seal squarely into the timing cover bore until it is fully seated and flush with the cover surface. Ensure the seal is not cocked or damaged during installation.
   ⚠The seal must be installed perfectly square to prevent leaks. Use the correct size driver tool for even installation.
8. 8

   Apply sealant and install timing cover gasket
   Apply a continuous 3-4mm bead of Toyota Genuine FIPG or equivalent RTV sealant to the timing cover mating surface, following the bolt hole pattern. If using a gasket, position it on the timing cover. Pay special attention to the oil pan junction area. Install the timing cover within 3 minutes of applying sealant.
   ℹ️RTV sealant begins to cure within 3-5 minutes. Work quickly and ensure cover is properly positioned before bolts are tightened.
9. 9

   Install and torque timing cover
   Carefully position the timing cover onto the engine block, ensuring proper alignment. Install all timing cover bolts finger-tight first. Tighten the 10mm head bolts to 45 Nm (33 lb-ft) in a crisscross sequence from center outward. Then tighten the 8mm head bolts to 25 Nm (18 lb-ft) in sequence. Install and torque the oil pan front section bolts to 12 Nm (9 lb-ft).

10. 10

    Install crankshaft pulley
    Clean the crankshaft nose and pulley bore. Align the crankshaft pulley with the crankshaft (observe any keyway or alignment marks). Install the pulley onto the crankshaft. Apply a light coat of clean engine oil to the crankshaft bolt threads. Install the crankshaft pulley bolt and hold the crankshaft with the holding tool. Torque the bolt to 180 Nm (133 lb-ft). If the bolt is TTY, replace with new bolt per manufacturer specification.

11. 11

    Reinstall right engine mount
    Position the right engine mount and bracket assembly. Install and torque the mounting bolts to specification (20 lb-ft for smaller bolts, 35 lb-ft for critical mounting bolts). Remove the engine support fixture once mount is secured.

12. 12

    Reinstall accessory components
    Reinstall the alternator (if removed), drive belt tensioner, and any other removed components. Reconnect all electrical connectors. Install the serpentine drive belt by rotating the tensioner and routing the belt per the underhood diagram.
13. 13

    Install drain plug and refill fluids
    Install the oil drain plug with a new crush washer and torque to 35 Nm (26 lb-ft). Install a new oil filter. Refill the engine with 5.0 quarts of Toyota Genuine 0W-20 engine oil. Refill coolant system with Toyota Super Long Life Coolant (Pink) to the proper level.

Reassembly

1. Reinstall the inner fender liner and splash shield
2. Reinstall the right front wheel and torque lug nuts to specification
3. Lower vehicle to ground
4. Reconnect negative battery terminal
5. Allow RTV sealant to cure for at least 2 hours before starting engine (check sealant manufacturer specification)

Verification

• Start the engine and verify proper oil pressure on gauge or warning light extinguishes within 3-5 seconds
• Check for oil leaks around the timing cover, particularly at the crankshaft seal area
• Allow engine to reach operating temperature and verify no coolant leaks
• Check engine oil level and top off if necessary
• Monitor for leaks over the next 24 hours and after first drive cycle
• Verify no abnormal noises from timing cover or accessory drive area
