2003 Lexus ES 300 TIMING BELT Removal And Installation Manual

TIMING BELT Removal (ES 300) 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. Remove crankshaft pulley bolt. Using puller, remove crankshaft pulley. Remove No. 1 and No. 2 timing belt covers and gaskets. See Fig. 1 . Remove transverse engine mounting bracket from front of engine. 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 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 it contacts the crankshaft and camshaft sprockets.

1) Park your truck on flat level surface. Chock the rear wheels. Loosen front lug nuts. Raise the front with a floo jack. Support the frame with jack stands. Remove front wheels. NOTE : ALWAYS USE JACK STANDS – NEVER RELY ON JACKS ONLY!! 2) Starting on the drivers side, locate the height adjusting bolt at the rear of the torsion bar. Measure and record the length of the threads exposed between the end of the adjusting bolt and jam nuts (Fig. A). Now make a mark at the front of the torsion bar, where it goes into the bracket bolted the lower control arm. Mark bath the bar and the bracket (Fig. B). This will index the bar into the correct position when installing. Fig. A Fig. B Note : Step #2 assumes torsion bars are in the factory position. 3) Loosen the height adjusting bolts until there is no longer any load on the torsion bars. 4) Remove the 2 bolts that hold the tension\compression rod and sway bar end link bolts. 5) Now remove the two bolts on each arm that holds the torsion bar receiver to the back of the control arm. Slide the torsion bar and receiver back from the control arm. There is a wide spline on the torsion bar corresponding to the double width tooth on the torsion bar receiver. The receiver will not slide back onto the bar if the splines are not aligned properly. 6) Loosen and remove the 3 nuts and bolts that hold each ball joint to the lower control arms. 7) Remove the pivot bolts holding the lower control arm to the frame and remove control arm from truck. 8) Unbolt and remove original bump stops from factory arms and bolt them to you new DJM control arm. 9) Drill out the small hole on the end of the torsion bar receiver to 7/16″on both sides. This is to accept the 7/16″ x 5- 1/2″ bolt supplied. 10) Compare the new DJM control arms with the factory ones. Carefull note the diameter of the factory ball joint mounting holes. You will find either three 10mm hole used on most earlier models or larger 13mm holes on late models. If you factory arms have the 10mm holes continue to step # 10. If factory holes are 13mm it will be necessary to enlarge the holes with a 1/2″ drill bit(Fig. C). Fig. C 11) Mount the DJM control arms to the truck. Make sure the steering stops are facing the front of the truck. Insert the pivot bolts and install the washers and nuts. DO NOT TIGHTEN YET . 12) Bolt on the tension\compression rods to the lower control arms. It mat be necessary to loosen the large nuts that hole the tension\compression rods to the frame in order to rotate the rods to the proper angle to align bolts into control arms.
