Remove any oil or water on the idler pulley and keep it clean.

1. Temporarily install the No. 1 idler pulley with the retaining bolt. Hint: use a 1.65 inch (42mm) bolt in length. Do not tighten the bolt yet. Install the tension spring. Pry the pulley toward the left as far as it will go, then tighten the bolt.
2. Turn the crankshaft until the key groove in the crankshaft timing pulley is facing upward. Install the timing belt on the crankshaft timing, oil pump, No. 2 idler and water pump pulleys.

If the old timing belt is being reinstalled, make sure the directional arrow is facing in the original direction and that the belt and crankshaft gear matchmarks are properly aligned.

1. Install the lower (No. 1) timing belt cover and new gasket with the four bolts.
2. Align the crankshaft pulley set key with the pulley key groove. Install the pulley. Tighten the pulley bolt to 80 ft. lbs. (108 Nm).
3. On 2S-ELC engines, turn the crankshaft pulley and align the 0 mark on the lower (No. 1) timing belt cover.
4. Align the camshaft knock pin with the matchmarks on the oil seal retainer.
5. On 2S-ELC/USA engines, align the knock pin with the pin hole on the timing pulley E mark side. On 2S-ELC/Canadian engines, align the knock pin with the pin hole on the timing pulley. On 3S-FE and 5S-FE engines, align the knock pin with the groove of the pulley, and slide the pulley onto the camshaft with the plate washer and set bolt.

On 2S-ELC engines, make sure that the Matchmark on the oil seal retainer and center hole of the small hole on the camshaft timing pulley are aligned.

1. Using the removal tool to hold the pulley stationary, install and tighten the pulley set bolt to 40 ft. lbs. (54 Nm) on the 2S-ELC and the 3S-FE. On the 5S-FE, tighten the set bolt to 27 ft. lbs. (37 Nm).
2. On 3S-FE and 5S-FE engines, turn the crankshaft pulley and align the 0 mark on the lower (No. 1) timing belt cover.
3. Install the timing belt and check the valve timing as follows:
   1. Align the matchmarks that you made previously, and install the timing belt onto the camshaft pulley.
   2. Loosen the No. 1 idler pulley set bolt 1 / 2 turn.
   3. Turn the crankshaft pulley two complete revolutions TDC to TDC. ALWAYS turn the crankshaft CLOCKWISE. Check that the pulleys are still in alignment with the timing marks.
   4. Tighten the No. 1 idler pulley set bolt to 31 ft. lbs. (42 Nm).
   5. Make sure there is belt tension between the crankshaft and camshaft timing pulleys.
   
   
4. Install the upper (No. 2) timing cover with a new gasket(s). On the 5S-FE, align the two clamps for the engine wiring harness with the cover mounting bolts.
5. Install the spark plugs.
6. Install the right mounting insulator with bracket. Tighten the bracket bolts to 38 ft. lbs. (52 Nm), insulator nuts to 38 ft. lbs. (52 Nm) and thru-bolt to 52 ft. lbs. (71 Nm). On the 5S-FE, install the No. 2 engine mount bracket and tighten to 38 ft. lbs. (52 Nm); install the control rod and tighten the bolts to 47 ft. lbs. (64 Nm).
7. Lower the engine.
8. On 3S-FE and 5S-FE engines, install the alternator and alternator bracket. On 2S-ELC engines, install the power steering reservoir tank.
9. Install the drive belt and adjust the tension.
10. Install the cruise control actuator with bracket.
11. Install the fender apron seal and right engine under cover.
12. Install the right front wheel.
