First with a 1/2 drive rachet release the tension and the neopream belt. Then with a socket take out only nut holding the pulley. Replacment will guide and only fit one way.
it is the idler pully. i just replaced mine and all the whining stopped
first you should release the belt tension pully and remove the belt. Then the idler pully has a bolt through the center remove the bolt and the pully should come off.
Pin the top tension idler pully..take the front wheel off...the bottom idler pully is on an excentric...loosen same....belt goes slack.... put new belt on,set the excentric as tight as possible.. remove the pin in the top tension idler pully belt should be tight after doing this... happy days
Most technicians refer to the idler pully for the timing belt as just idler.
It could be a bad bearing in the idler pully, A/C clutch, ect. Try turning on the A/C to see if it changes the squeek.
No you can not. If belt is loose, are won't fit then you have the wrong belt. The belt tensioner is spring loaded and that is what tightens the belt.
Idler PulleyI recently replaced a idler pulley on my Chevy 305 v8 from Auto Air of Oklahoma. Their web site is www.autoairofoklahoma.com, you might try them, I looked everywhere for a idler pulley before I found these guys. TJ
I have a knocking noise near the water pump pully or idler arm pully on my 94 chevy cavalier 2.2 motor when its at idle, if i give it more gas the noise will go away do you know what this could be? i took off the tension idle pully and checked the bearing and it was fine.
a 92 Silverado 350 uses a single serpentine belt that is tensioned by a spring loaded idler pully. When facing the engine from the front of the vehicle, the tensioner is near the top of the engine slightly left of center. Using a breaker-bar and socket, remove tension from the idler pully and simultaneously slide the serpentine belt off one of the other pulleys. I usually pick the alternator pully since it's so close. Note the path of the old belt and make certain that the new belt is installed along the identical path. Put the belt on all pullies, including the idler pully and hold it with slight tension near the alternator pully, then turn the idler pully again and slide the belt over the alternator and release pressure from the idler pully. Visually inspect the path of the entire belt to make certain that it is properly installed before starting the engine. Don't let anyone stand to the side of the engine when starting it for the first time, since a mis-installed pully can be ripped apart quickly and relatively large pieces of reinforced rubber can really hurt when they hit you.
remove the bolt on the pully or use a pully remover depending on the style of pully and put new one on.
Unbolt, slide off. Slide on new part, bolt back on.
remove belts idler is to close to fire wall to come off after you remove nut.jack up car and put stands under.how put a jack under engine . remove top motor mount bolt and jack engine up this will give you the room to change idler pully.
