Idler Pulley Removal

Buy a tool called an "easy out" its like a threaded screw with a fine point on the end of it and the other end has a spanner or socket fitting. You drill through the centre of the broken bolt , insert the easy out and screw the easy out into the hole. The easy out is a left hand thread , so as you are "tightening" the easy out, it is actually undoing the broken bolt. Spray bit of CRC or WD 40 around the broken bolt to assist its removal.

Adjusting aircon belt on HZJ75 motor.
1 Loosen bolt at centre of idler pulley. Idler pulley is smaller pulley adjacent to the Aircon pulley.
2 Rotate the adjuster bolt clockwise to tighten belt. The adjuster bolt head sits directly above and behind the idler pulley.
3 Anti clockwise will loosen the belt. Wind to end of the adjustment to remove or replace belt then rewind bolt clockwise to required belt tension.
4 Retighten bolt at centre of idler pulley following any adjustments.

Locate the idler pulley to the left of the crankshaft pulley. The idler pulley bolts to the idler arm. The idler pulley is replaced with the arm because they are sold as one unit.

2 Place a 3/8-inch ratchet driver into the square hole on the face of the idler pulley and pull up on the handle. This releases tension on the Sonoma's serpentine belt. Pull the belt off the idler pulley, lower and remove the ratchet handle.

3 Remove the two bolts that secure the idler arm to the engine block using a socket and ratchet, and discard the old idler arm.

4 Place the new idler arm against the engine block and secure it using the socket and ratchet.

5 Put the ratchet driver into the square hole on the new idler pulley, pull up on the handle and place the serpentine belt over the pulley.

6 Lower and remove the ratchet handle.

Installation
1.Install No. 2 idler pulley (if removed). Install and tighten bolt to specification. See TORQUE SPECIFICATIONS . Ensure idler pulley is clean and rotates smoothly. 2.Install No. 1 idler pulley and tension spring (if removed). Pry No. 1 idler pulley away from timing belt area as far as possible. Temporarily tighten No. 1 idler pulley bolt. Ensure idler pulley is clean and rotates smoothly. 3.Using crankshaft pulley bolt, rotate crankshaft so timing mark on crankshaft sprocket aligns with timing mark on oil pump housing. See. This will position keyway in crankshaft sprocket at 12 o'clock position.

CAUTION:If reusing timing belt, ensure reference marks on timing belt align with reference marks placed on crankshaft and camshaft sprockets. Ensure timing belt is installed in original direction of rotation.
4.Ensure all sprockets and idler pulleys are clean.

Install No. 1 timing belt cover and new gasket. 6.Align crankshaft pulley key groove with key in crankshaft. Install crankshaft pulley. Install and tighten crankshaft pulley bolt to specification. 7.Rotate crankshaft clockwise so cylinder No. 1 is at TDC on compression stroke. Ensure timing mark on crankshaft pulley aligns with "0" mark on No. 1 timing belt cover. If reusing timing belt, ensure reference mark on timing belt aligns with upper edge of No. 1 timing belt cover. 8.Rotate camshaft, and align hole in camshaft sprocket with alignment mark on camshaft bearing cap. See Fig. 2 . Install timing belt on camshaft sprocket. If reusing timing belt, ensure reference mark on timing belt aligns with the reference mark on camshaft sprocket. Ensure tension exists on timing belt between the crankshaft and camshaft sprockets.
CAUTION:DO NOT rotate crankshaft counterclockwise, as viewed from timing belt end of engine.
9.Loosen No. 1 idler pulley bolt 1/2 turn. Rotate crankshaft pulley 2 full revolutions clockwise from TDC to TDC. 10.Ensure timing mark on crankshaft pulley aligns with "0" mark on No. 1 timing belt cover, and hole in camshaft sprocket aligns with alignment mark on camshaft bearing cap. See Fig. 2 . If timing marks are not aligned, remove timing belt and reinstall. 11.Rotate crankshaft clockwise 1 and 7/8 revolutions and align crankshaft pulley "0" mark with 45-degree Before Top Dead Center (BTDC) mark on No. 1 timing belt cover. See Fig. 5 . 12.Tighten No. 1 idler pulley bolt to specification. See TORQUE SPECIFICATIONS . Install No. 2 timing belt cover and gaskets. Install and tighten spark plugs to specification. 13.To install remaining components, reverse removal procedure. Install all bolts/nuts on right (timing belt side) engine mount before tightening to specification. 14.On Camry, when installing control rod and bracket on strut tower and right (timing belt side engine mount, tighten bolts to specification in sequence.

alternator and air conditioning compressor

1. Disconnect the negative battery cable.
2. Loosen the idler pulley bolt.

The replacement of the inner belt on multi-belted engines may require the removal of the outer belts.
To replace a drive belt, loosen the adjusting and mounting bolts of the component which the belt is driving. Move the component inward to relieve the tension on the drive belt.
Slip the belt off the component pulley and match the new belt with the old belt for length and width. The old belt will be slightly longer. After a new belt is installed correctly, adjust the tension.

1. Turn the adjustment bolt at the top of the idler pulley bracket. Clockwise rotation will tighten the belt; counterclockwise will loosen it.
   
2. Keep the idler pulley bolt snug (but not tight) while adjusting belt tension. The adjustment bolt should turn with moderate force.

After adjustment is satisfactory, tighten the idler pulley bolt, and then tighten the adjustment bolt.

Reconnect the negative battery cable.

When replacing more than 1 belt, it is a good idea to make note or mark what belt goes around what pulley; this will make installation easier if you mix up the belts.

Timing Belt and Sprockets REMOVAL & INSTALLATION 2S-ELC, 3S-FE and 5S-FE Engines

1. Remove the timing belt covers as previously detailed.
2. Raise the engine just enough to remove the weight from the engine mount on the right side.
3. Remove the thru-bolt, two nuts, and right hand mounting insulator.
4. Remove the retaining bolts and remove the right hand mounting bracket (from the side the alternator was removed from).
5. Remove the timing belt and timing belt guide. If the timing belt is to be reused, draw a directional arrow on the timing belt in the direction of engine rotation (clockwise) and place matchmarks on the timing belt and crankshaft gear.
6. Remove the bolt retaining the No. 1 idler pulley and tension spring.
7. Remove the No. 2 idler pulley.
8. Remove the crankshaft timing gear , if it can not be removed by hand, use two flat bladed tools to pry it off. Make sure to position shop rags to prevent damages to the components.
9. Remove the nut retaining the oil pump pulley. To install:
   
10. Align the cutouts of the oil pump pulley and shaft, and slide the pulley on. Retain the pulley while tightening the nut to 21 ft. lbs. (28 Nm).
11. Align the crankshaft timing pulley set key with the key groove of the crankshaft pulley, then slide the pulley on.
12. Install the No. 2 idler pulley with the bolt and tighten to 31 ft. lbs. (42 Nm). Be sure the pulley moves smoothly. NOTE: Remove any oil or water on the idler pulley and keep it clean.
    
13. 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.
14. 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. NOTE: 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.
    
15. Install the lower (No. 1) timing belt cover and new gasket with the four bolts.
16. Align the crankshaft pulley set key with the pulley key groove. Install the pulley. Tighten the pulley bolt to 80 ft. lbs. (108 Nm).
17. On 2S-ELC engines, turn the crankshaft pulley and align the 0 mark on the lower (No. 1) timing belt cover.
18. Align the camshaft knock pin with the matchmarks on the oil seal retainer.
19. 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. NOTE: 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.
    
20. 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).
21. On 3S-FE and 5S-FE engines, turn the crankshaft pulley and align the 0 mark on the lower (No. 1) timing belt cover.
22. 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.
23. 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.
24. Install the spark plugs.
25. The remainder of installation is the reverse of removal. Tighten each component to specifications.

Pretty easy for average mech. first drain coolant by loosening the lower radiator hose.
Make sure to have a drain pan. remove the power steering belt by removing the bolts to the idler pulley. and let belt off the pulley.remove the alternator upper bracket. and remove belt.
Take fan shroud off with two 8mm bolts on top oe it.
You cant remove untill you remove the clutch fan assembly.
It is left handed thread.
It has to be removed together.
Remove the four bolts to the pulley on front of water pump. and then remove all 14mm bolts around the pump.
Then remove 8mm bolts and it will be able to come off. assemble in reverse order!

Once the belt is removed, the center bolt from the idler pulley should unscrew normally with a socket. The replacement pulley bolts back in with the same bolt, then just put the belt back on. The bolt should be very snug, but do not overtighten ir it will shorten the life of the idler. As tight as you can get it with one hand using a typical 3/8" ratchet should be adequate. There should be a belt routing diagram on a sticker under the hood. Belt removal and reinstallation is achieved by using a 3/8" drive ratchet or breaker bar to engage the square hole on the spring loaded tensioner arm and flex it clockwise on most engines. On other GM engines, placing a socket on the center bolt of the tensioner pulley and turning clockwise will flex the tensioner to loosen the belt. When you have the belt off, check all pulleys for smooth rotation and listen for squeaking. If any of them bind or squeak, they should be repaired/replaced as well. Installing a new belt is also a good idea when replacing the idler.
