Replacing idler pulleys and fan belt??
Just bought a new gates kit because my new car is squeaking like a mouse getting shafted by an elephant... Wondering if anyone could show me a diagram of the pulleys ive got and where they go, 2 of them a metal and one of them is either plastic or resin of some sort and then theres the fan belt.....they are all "idler pulleys" im guessing this couldnt be that hard for me to figure out with the right advice...i can sorta tell which ones i wouldnt take off, water pump etc. But some of them still look alike...its a vs exec ii 95 model
Two of them will go either side of the air conditioning compressor,and the other will go on the serpentine belt tensioner.Ive just done the bearings in all of mine.Around $8 each for the idler pulley bearings and $6 for the tensioner pulley bearing.It has made a huge difference to how smooth it runs,I should have done them ages ago.
is the plastic one for the tensioner??? the metal ones are different sizes too, im guessing the air conditionin compressor is at the top?? do you know which side the big or small pulley will be attached or should i be able to tell next time i look?....thanks for helping
Heres a pic of the belt and pulley setup..Dont know why it turned out so big.
sick ****....but still got the question is the plastic one the tensioner or should i just be able to tell?? i looked earlier and from memory they were all metal inside the car at the moment
I thought the idler pulleys were around the same size ,and I thought they were a similar size to the tensioner pulley (although the bearings in them are all different sizes).How much difference is there in the sizes of the ones you bought?
i figured out what goes where now i just need to know...is it easy as just taking it off and putting the new one on or is there any special attention i need to take??...things arent usually as easy as they look
Im pretty sure the plastic one goes on the tensioner.I have a metal one on my car but looking at the pictures of the engine in the gregorys workshop manual it looks like its a plastic one fitted.I know they fitted some plastic ones to the two idler pulleys near the air conditioner compressor as well.Mine are both metal.Its heaps cheaper to just replace the bearings if you already have metal pulleys.Around $20 for the 3 bearings.Originally Posted by strikewon

****in lol... So, incase I've forgotten what that sounds like, can you describe it to me...?
With out looking, and at a guess, I'd say the plastic one has grooves on it - to run on the inside of the belt, making it the 'top idler' pulley. The other idler would be smooth metal - to run on the back of the belt, making it the lower idler pulley.
With the sizes of the two metal ones, just match them up to the original ones on the motor already
well the plastic one is ribbed to fit the under side of the belt wich is exactly the same as the idler (in my car) thats inbetween the bottom idler and the tensioner (in your diagram) when i look under the bonnet...if that made sense..so im guessing that its the one in the middle! well its the same so it would have to be...so yeah now i just wanna know about actually going thru with replacing it myself..can you give me tips...???
yes your exactly right but the way its set up in my car now is that the idler with grooves in it is in the middle?? has this been done wrong!?!?! lol could it be the reason why my car sounds like estranged animals fornicating****in lol...

pretty ****ing squeaky!!!

The tensioner pulley and the bottom idler pulley should have flat pulleys.The "middle" idler pulley should have grooves.
yes i just followed the diagram and thats correct...the way it is in the car already......still unanswered...is it a hard job...do i have to pay attention to anything??? cheers for allyour help!!!

'Top idler' in Brett jjj's pic, so the one directly to the right of the water pump pulley looking at the motor.
The 'top' pulley, under the alternator is the tensioner pulley - smooth metal one, then working clockwise around the motor, top idler pulley - black plastic grooved one, then below that one another smooth metal one.

Don't think there's a trick to them?
Only ever pulled one of them off to get at a water pump once... Just undid it, then put loctite on the bolt when I put it back in
(might be a reverse thread though? don't think so though
ive herd about there being a reverse thread is this on all of the bolts??? im guessing i should put the fan belt on before i bolt the last pulley in order to have it strapped around tightly? and loctite..is this some sorta glue?
If i remember correctly the tensioner pully is a reverse thread, all the rest are normal, easy job just make sure you put the belt back on the correct way, follow bretts pic if you cant remember, good luck
cool so just the tensioner...should i do this one first??? theres something about it moving so i can remove the belt im just a bit confused about that aswell as reattaching the bolt with the reverse thread someone wrote that you turn it anti clockwise to loosen the belt and then clockwise to remove the actual pulley??? how does this reattach?? just trying to get as much info as possible before tomorrow when i make my attempt!!! lol
wont really matter what one you do first, i thought it was clockwise to loosen the belt and anti-clockwise to undo the bolt but may be wrong its been a while since i owned a vs, the tensioner is spring loaded incase you didn't know, its not hard job just suss it out you'll be fine, loctite is a type of glue so might pay to get sum from autobarn or repco or somewhere before you start, you just put a little bit on the thread of the bolt before you put it back in and do it up
all possible with a spanner it seems...you have all been a great help....mad bastards!!! have a good evening
"..of mice and men.."
Install all of the new pulleys you have, including the water pump's pulley, and just do them as tight as you can without the belt on.
Not sure about other models, but on my VS, they are all metal pulleys, only my VR has a plastic tensioner pulley.
Install the belt as shown in the previous pics(my pics show the air-con set-up).
Upper left area-
Lower right area-
Use a 15mm spanner or socket, and push DOWN to turn tensioner pulleys center nut anti-clockwise, to slip the belt up over the top.
Once the belt is over and square on all of the pulleys, let the tensioner to it's normal position, belt is ready to go.
Then you can do a final nip up on the water pumps pulley bolts.

im pretty sure the watter pumps pulley is all sweet just the idlers....
The tensioner pulley is definately LH thread to undo (clockwise direction). The other 2 pulleys are RH thread to undo (anti clockwise).
