You need to post year, make, model and what engine?
also which idler pulley? I'm guessing you're probably looking at the accessories drive belt ("fan belt") idler pulley bracket.
Is this a serpentine belt.
a lot of cars use Idler and or tensioner pulleys on the timing belt/chain. the Idlers often don't have brackets
why are you replacing the bracket? did you break it? or do you just need the pulley? I normally replace both pulleys (idler and tensioner) when replacing either one.
anyways.. need a lot more info to answer your question

Please could you give me a diagram of the valve timing of a double O.H.C.on a toyota Rav4 3SFE engine

no year(94-present) stated. and under kia dont help much.

its at, i read all the steps and not skip one, I WOULD.

wild guess, #1 a 2005 RAV4
2.0L 3sfe. inline 4 cylinder, not V6

here is the one i see on the FSM.

my gates belts all come with a manual. RTM?
if you buy the belt at a dealer they assume you have the FSM.
FSM, install, steps
  1. Install the oil pump pulley. Tighten the nut to 18 ft. lbs. (24 Nm).
  2. Install the crankshaft timing pulley. Align the pulley set key with the key groove of the pulley. Slide on the pulley facing the flange side inward.
  3. Install the No. 2 idler pulley and tighten the mounting bolt to 31 ft. lbs. (42 Nm). Be sure that the pulley moves smoothly.
  4. Install the No. 1 idler pulley with the bolt and the tension spring. Pry the pulley toward the left as far as it will go and tighten the bolt. Make sure that the pulley moves smoothly.
  5. Temporarily install the timing belt. Using the crankshaft pulley bolt, turn the crankshaft and position the key groove of the crankshaft timing pulley upward. If reusing the timing belt, align the points marked during removal.
  6. Install the timing belt on the crankshaft timing pulley, oil pump pulley, No. 1 idler pulley, water pump pulley and the No. 2 idler pulley.
  7. Install the timing belt guide.
  8. Install the lower (No. 1) timing belt cover and new gasket with the 4 bolts.
  9. Align the crankshaft pulley set key with the pulley key groove. Temporarily install the crankshaft pulley and bolt.
  10. Align the camshaft knock pin with the groove of the pulley, and slide the timing pulley onto the camshaft with the plate washer and set bolt.
  11. Tighten the pulley set bolt to 40 ft. lbs. (54 Nm).
  12. Turn the crankshaft pulley and align the 0 mark on the lower (No. 1) timing belt cover.
  13. Finish installing the timing belt and check the valve timing, as follows:
    1. If reusing the old timing belt, align the matchmarks made previously and install the timing belt onto the camshaft pulley.
    2. Align the marks on the timing belt with the marks on the camshaft pulley.
    3. Loosen the No. 1 idler pulley set bolt 1 / 2 turn.
    4. Turn the crankshaft pulley 2 complete revolutions TDC to TDC. ALWAYS turn the crankshaft CLOCKWISE. Check that the pulleys are still in alignment with the timing marks.
    5. If the No. 1 idler pulley uses a green tension spring, slowly turn the crankshaft pulley 1 7 / 8 revolutions, and align its groove with the mark at 45 degrees BTDC (for the No. 1 cylinder) of the No. 1 timing belt cover.
    6. Tighten the No. 1 idler pulley set bolt to 31 ft. lbs. (42 Nm).
    7. Be sure there is belt tension between the crankshaft and camshaft timing pulleys.
  14. Place the right-hand engine mounting bracket in position but do not install the bolts.
  15. Install the upper (No. 2) timing cover with a new gasket(s).
  16. Remove the engine crankshaft pulley bolt and pulley.
  17. Using SST 09249-63010, or equivalent, install the mounting bolts for the right-hand mounting bracket. Tighten the mounting bolts to 38 ft. lbs. (52 Nm).
  18. Align the crankshaft pulley set key with the pulley key groove. Install the pulley. Tighten the pulley bolt to 80 ft. lbs. (108 Nm).
  19. Install the spark plugs.
  20. Install the right-hand mounting insulator, as follows:
    1. Attach the mounting insulator to the body and mounting bracket with the 4 bolts and 2 nuts.
    2. Tighten the 3 bolts to hold the mounting insulator to the body. Tighten the bolts to 47 ft. lbs. (64 Nm).
    3. Tighten the 2 nuts and bolt to hold the mounting insulator to the mounting bracket. Tighten the bolt to 27 ft. lbs. (37 Nm) and the nut to 38 ft. lbs. (52 Nm).
  21. Install and adjust the power steering pump drive belt.
  22. Install the right-hand engine undercover.
  23. Install the right front wheel.
  24. Lower the engine.
  25. If equipped, install the ABS actuator.
  26. Install the alternator and alternator bracket.
  27. Install the wiring harness bracket for the DLC1.
  28. Install the power steering reservoir bracket and reservoir.
  29. Connect the negative battery cable.
  30. Start the engine and check the timing.

step 13.4 is never to be skipped. ask why., most do. and it fails.

Replace idler pully on 92 Nissan. Pathfinder 4~4

Looks like there is an idler pulley for the ac belt. The alternator and ps belts are adjusted by moving the components.
The pulley is available without the bracket, so you should be able to loosen the center bolt without removing the bracket. There is an adjusting bolt or rod that you turn to tighten or loosen the belt once you have loosened the bolts for the bracket.

What makes a belt squeak?

Belts squeak for the same reason tires do when they spin. They are slipping. Something isn't turning as fast as the belt wants it to. On ford it's usually ether the idler sprocket or the tensioner. If you remove the belt and try spinning all of the pulleys by hand.( note the crank wont spin freely) you will usually be able to tell witch ones slipping.

serpentione belt sounds as if it is stretched. first try to reseat serpentine belt. if still a problem then go buy new belt at autozone. also buy some belt dressing. this should fix the problem. if this doesnt solve then you need to buy a new idler arm. relatively easy fix.

How do you change the alt.

1) Disconnect negative battery cable. Jack up right front of car. Be sure to protect yourself with jackstands and rear wheel chocks. Safety first!
2) Remove the engine undercover (plastic under engine protector) on the right side
3) Remove the right front wheel.
4) Remove the right hand side inspection cover inside the wheel well. (I did not say this was a simple job.)
4a) Optional: Curse Nissan engineers for lack of foresight in maintenance.
5) Loosen the belt idler pulley (center of the pulley itself, I think its 14mm, but Do NOT loosend the bracket bolt)
6) Loosen the idler pulley tension (large, vertical nut above the idler pulley)
7) Remove the belt.
8) Replace with new belt.

Install is opposite of removal. You may have to wiggle a bit to slip it on correctly, but be patient, it will go
To replace alternator:

9) Get your **** under the car, fully supported on jackstands, and remove the 4 Air conditioner bolts
10)Slide the A/C compressor forward (don't drop it on your head!)
11) Disconnect the alternator harness connector (This may be tricky to do while mounted. If so, then with the help of a friend, remove the alternator following the steps below and remove the connection after the alternator is loose. DO NOT let the alternator hang by the wiring harness connections.)
12) Remove the wiring harness bracket from the alternator.
13) Remove the alternator upper and lower bolts. Slide Alternator down and forward to remove.
14) Install is opposite of removal.
Good Luck!

check the idler/tensioner pully's and the alternator pully, there is a common problem with one of these 3 going bad, usually an idler pully the best way to check is to get a mechanics stethescope and touch the end to the bolt on the idler pully's you will notice a very distinct sound difference from a smooth pully and one with bad bearings. gm tech here, seen many of these

Change idler pulley

It's a T-40 size, but I removed the bolt by first removing the bracket holding the pulley--I assume you're talking about the alternator idler pulley, the one right below the alternator. The bracket is held in place by three 14 mm bolts which I was able to reach from the top of the engine (after removing the black plastic air tube). I then put the bracket in a vise and "buzzed" off the 14 mm nut using an electric impact wrench ($30 +/- from Heartland of America). Be careful when putting the nut back on--the impact wrench will likely be too much torque!

Alternator idler pulley replacement.


Compare the new pulley to the old one. I think you'll find you have been supplied with the wrong pulley.

Very best regards
