  Q: How to remove and install the timing belt on Toyota Avalon?

  A: You should begin timing belt removal by taking off the RH front wheel followed by the fender apron seal before proceeding with generator Drive Belt and PS pump drive belt bolt removal. The timing belt removal procedure starts with disconnecting the engine coolant reservoir hose from the water outlet then breaking the ground strap connectors while removing the engine moving control rod and No.2 RH engine mounting bracket and No.2 generator bracket by loosening the pivot bolt followed by removing the nut and bracket. Special Service Tools 09213-54015 (91651-60855) and 09330-00021 and 09950-50012 (09951-05010, 09952-05010, 09953-05010, 09953-05020, 09954-05020) should be used to remove the crankshaft pulley components. First remove the 4 bolts from the No.1 timing belt cover followed by removing the timing belt guide and then proceed to remove the No.2 timing belt cover after disconnecting engine wire protector clamps and precision removal of the 5 bolts. Start by removing the 2 bolts and nut securing the RH engine mounting bracket. After which install the crankshaft pulley bolt temporarily to align the timing marks while rotating the crankshaft at TDC/compression and verify the Camshaft timing pulleys. Every timing belt should get a thorough examination to detect its three installation marks and one front mark. New marks must be placed first whenever existing marks are not visible before removing the timing belt. Begin with timing belt tensioner removal after 2 bolt rotation then disconnect the timing belt before moving on to the camshaft timing pulleys. Special Service Tools 09249-63010 and 09960-10010 (09962-01000, 09963-01000) are needed for Right-hand and Left-hand timing pulley service respectively. The technician should begin by using a ten-millimeter hexagon wrench to remove the No.2 idler pulley and the No.1 idler pulley before moving on to the crankshaft timing pulley removal through the procedure of bolt and timing belt plate removal along with the use of Special Service Tool: 09950-50012 (09951-05010, 09952-05010, 09953-05010, 09953-05020, 09954-05010) to lift out the pulley while preserving the sensor part from scratching. Check the timing belt for defects while it must stay straight and untwisted and avoid contact with oil water and steam. Also inspect for any oil leakage from the idler pulleys and timing belt tensioner as well as their smooth operation. Installation should begin with the crankshaft timing pulley by aligning its pulley set key followed by installation of the timing belt plate which requires 8 Nm (80 kgf-cm, 69 inch lbs.) of torque before applying Part No. 08833-00080 adhesive like THREE BOND 1344, LOCTITE 242 or equivalent to the No.1 idler pulley and torquing to 34 Nm (350 kgf-cm, 25 ft. lbs.). After installing the 43 Nm torque (440 kgf-cm, 32 ft. lbs.) No.2 idler pulley attach the RH camshaft timing pulley with the flange side facing outward before torquing the pulley bolt to 88 Nm (900 kgf-cm, 65 ft. lbs.) using Special Service Tool: 09249-63010, 09960-10010 (09962-01000, 09963-01000). Fasten the LH camshaft timing pulley with its flange facing inside and complete the torque to 125 Nm (1,300 kgf-cm, 94 ft. lbs.). Set the No.1 cylinder at TDC/compression while verifying the timing marks' position before installing the timing belt according to sequence when the engine remains cool and pulleys are cleaned. The timing belt tensioner needs setting through the use of a 1.27 mm hexagon wrench to activate the push rod followed by installation and bolt tightening to 27 Nm (280 kgf-cm, 20 ft. lbs.). Flip the crankshaft twice to check timing marks but keep the timing belt if any marks fail to align. Installation of the RH engine mounting bracket requires 28 Nm (290 kgf-cm, 21 ft. lbs.) torquing followed by No.2 timing belt cover installation with a 5-bolt torque to 8.5 Nm (85 kgf-cm, 74 inch lbs.). Install the timing belt guide then the No.1 timing belt cover before adding the crankshaft pulley with proper key alignment while torquing the bolt to 215 Nm (2,200 kgf-cm, 159 ft. lbs.). Reinstall the RH fender apron seal and front wheel following a vehicle road test which checks for abnormal noise, shock, slippage, correct shift points and smooth operation. The final assembly includes the No.2 generator bracket, the No.2 RH engine mounting bracket and engine moving control rod, along with reconnecting ground strap connectors and coolant reservoir hose and drive belts installation.
