REMOVAL & INSTALLATION

TIMING BELT

Removal (Camry, Camry Solara & ES 330)

1. Raise and support vehicle. Remove right side front wheel. Remove right fender apron seal. Remove accessory drive belts. Lower vehicle. Disconnect engine coolant reservoir hose from water outlet. Disconnect ground strap connectors.

2. Remove engine moving control rod and engine mounting bracket No. 2 (right side), located near timing belt cover. Remove generator-to-engine bracket for access to timing belt covers.

3. Using Pulley Holder (09213-54015) or equivalent and Handle (09330-00021) or equivalent, hold crankshaft pulley. Loosen crankshaft pulley bolt. Using puller and crankshaft pulley bolt, remove crankshaft pulley. Remove No. 1 and No. 2 timing belt covers and gaskets. See Fig. 1 . Remove right side engine mounting bracket. Note direction of timing belt guide installation for reassembly reference. Remove timing belt guide.

4. Temporarily install crankshaft pulley bolt and washer in crankshaft. Using crankshaft pulley bolt, rotate crankshaft CLOCKWISE until timing mark on crankshaft sprocket aligns with timing mark on oil pump body. See Fig. 2 .

5. Ensure timing marks on camshaft sprockets are aligned with timing mark on No. 3 timing belt rear cover. See Fig. 2 . If timing marks are not aligned, rotate crankshaft CLOCKWISE one full revolution (360 degrees). Remove crankshaft pulley bolt.

6. If reusing old belt, ensure there are 3 installation marks and front arrow marked on belt. See Fig. 3 . If not, place mating mark on belt where timing belt contacts crankshaft and camshaft sprockets. Also, mark belt with arrow showing direction of rotation.

7. Turning crankshaft pulley, set cylinder No. 1 to about 60 degrees BTDC. See Fig. 4 .

8. Alternately loosen 2 bolts, and remove timing belt tensioner and dust boot. DO NOT hold tensioner with

WARNING: To prevent air bag deployment, disconnect negative battery cable at least 90 seconds before working on vehicle.

CAUTION: This application is an interference engine. Do not rotate camshaft or crankshaft when timing belt is removed, or engine damage may occur.

NOTE: Always turn crankshaft clockwise, as viewed from timing belt side of engine.

CAUTION: If timing belt is disengaged, having crankshaft pulley at wrong angle can cause piston and valve to come in contact with each other when you remove crankshaft or camshaft pulleys, causing damage. Always set crankshaft pulley at correct angle.

Inspection (Camry, Camry Solara & ES 330)

1. Inspect timing belt for damaged teeth, cracking or oil contamination. Ensure idler pulleys rotate freely and are not leaking oil. Replace damaged components. Check water pump for leaks or worn out bearing.

2. Inspect timing belt tensioner for signs of oil leakage. Replace timing belt tensioner if oil leakage exists. Hold timing belt tensioner body with push rod facing UP. Press rod against solid surface. Replace timing belt tensioner if push rod moves.

Installation (Camry, Camry Solara & ES 330)

1. Install No. 1 and No. 2 idler pulleys (if removed). On No. 1 idler pulley bolt, coat threads with Loctite 242 or equivalent. Install and tighten bolts to specification. See TORQUE SPECIFICATIONS . Ensure idler pulleys are clean and rotate smoothly.

5. Using press, SLOWLY apply about 200-2200 lbs. of pressure on push rod of timing belt tension until rod is retracted and holes in rod and housing are aligned. See Fig. 5 . Align holes in housing and push rod to hold rod in retracted position. Install 1.5 mm hexagon wrench through housing and push rod hole to secure push rod. Release press and install dust boot on timing belt tensioner.

6. Install timing belt tensioner. Install and alternately tighten bolts to specification. See TORQUE SPECIFICATIONS .

7. Remove hexagon wrench from timing belt tensioner. Slowly rotate crankshaft CLOCKWISE 2 revolutions until timing mark on crankshaft sprocket aligns with timing mark on oil pump body.

8. Ensure timing mark on each camshaft sprocket is aligned with appropriate timing mark on No. 3 timing belt rear cover. See Fig. 2 . If all timing marks are not aligned, remove timing belt and reinstall. Remove crankshaft pulley bolt.

9. Install timing belt guide with cup facing out. Install engine mounting bracket on front of cylinder block. Install and tighten bolts to specification.

10. Using new gaskets, install No. 1 and No. 2 timing belt covers. Ensure there are no gaps in gasket. Cut off any excess gasket. Install and tighten bolts to specification.

11. Align crankshaft key with key groove of crankshaft pulley. Install crankshaft pulley. Install and tighten crankshaft pulley bolt to specification. See TORQUE SPECIFICATIONS .

12. Install generator bracket. Install engine mounting bracket No. 2 (right side) and engine moving control rod. Install fender apron seal and right front wheel.

13. To install remaining components, reverse removal procedure. Tighten fasteners to specification. See TORQUE SPECIFICATIONS . Connect engine ground strap. Adjust drive belts to proper tension.
