Can't get A/C belt around pulleys on my 01 Chevy Tracker 2.5 V6
Replacing belts. Got alt belt back on with major difficulties. Got A/C belt off after loosening tension bolt on idler pulley. Now can't get belt back on around idler puller. Any tricks or special tools needed?
I never had this much problem with my Ford van which has a tension spring idler type pulley.
Re: Can't get A/C belt around pulleys on my 01 Chevy...
If the belt on a 2.5 tracker goes on hard (like it's a inch too small) go the next size up on belt because if it's from AutoZone there belt listing is wrong.....check your idler pulley- belt adjuster too if the outside is shiny..chances are it could be no good

How-To Replace The Serpentine Belt On A Chevy Tracker ...2001 Chevy Tracker V6 2.5L Head Instal and Timing Chain Instal - Duration: ... XL 7 2.7L Air conditioning compressor removal and smaller belt installed - Duration:
2002 frontier 4 cyl: 1) take off air intake tube, 2 screws 13 mm above radiator. 2) 1st belt for power stirring has pulley, undo pulley screw and unscrew adjuster bolt enough to take belt off 3) 2nd belt for alternator and water pump has no pulley but adjusting bolt and mounting bolt on alternator pulley, loosen mounting bolt and unscrew adjusting bolt enough to take belt off, if alternator will not move go under the truck and remove plastic cover- 6 screws 13 mm heads, after that look directly under alt. Pulley and should see a screw head 9/16 in, loosen it so alternator can move, now should be easy to remove belt ( it will be a lot harder to put new one though) 4) 3rd belt for compressor has pulley so follow #2 to remove it ,have to be done under the truck. First 2 belts will have to work around fan blades to remove them so wear gloves. After replacing belts remember that not to over tighten bolt on pulleys.
Open the hood and locate the accessory belt routing diagram that is stamped to the top flat surface of the radiator shroud. Use the routing diagram to properly route the new belt around each accessory pulley. Look on the front of the engine between the alternator and the power steering pump and locate the automatic belt tensioner. Use the pulley that is attached to the end of the tensioner to loosen the tension from the belt. Position a breaker bar and a 14 mm socket onto the bolt head in the middle of the tensioner pulley. Turn the breaker bar clockwise to loosen the tension from the belt. Slide the belt off of the tensioner pulley and slowly release the breaker bar. Slide the belt out from around all of the engine accessory pulleys. Pull the belt around each of the fan blades and up out of the engine compartment. Slide the new belt around each of the fan blades and around each of the accessory pulleys as directed by the belt routing diagram. Turn the tensioner clockwise with the breaker bar and the 14 mm socket again. Slide the belt around the tensioner pulley and slowly release the breaker bar. Pull the breaker bar and socket off of the tensioner and out of the engine compartment. Crank the engine for ten to fifteen seconds to finish seating the ribs on the inside of the belt to the grooves of each accessory pulley. Turn the engine off.
GM use a particular item on one of the idlers
there will be a 1/2" square hole in the center of it
use a strong bar and lift the pulley up against a spring
install the new belt and when properly installed let the pulley back onto the belt
well its hard to describe but here goes. the belt will run across the top from the PS pump to the alt. from the alt to the inside of the water pump, then to the outside of the a/c comp . then around the crank pulley, then up to the inside of the tensioner, then up around the outside of the PS pump. It will be easier to put the belt around all the pulleys except the alternator, release the tensioner and with the belt loose, slide it over the alt pulley. GOOD LUCK. I hope you fixed the problem with the belt, they just dont fall off for no reason. ck tensioner pulley, water pump.
The belt typically won't squeal when too tight, it will just put more wear and tear on the components. I would recommend removing the belt, and cleaning the pulley with brake parts cleaner and a tooth brush. There is probably some sort of residue on the pulley, which is allowing the belt to slip when the a/c clutch engages. If this doesn't help, make sure all of your pulleys are aligned. Use a long straight edge to check their alignment with each other. If they aren't close to perfectly straight, it will cause the belt to ride funny and squeal when the a/c clutch engages.
A year is not a good sign. The belt should not have come off in that span of time. I would make sure you do not have a worn out idler or tensioner pulley bearing before installing your new belt or reinstalling the original if it is not worn or damaged.
You will find one or two small pulleys involved with drive belt. One of the smaller pulleys will be an "idler" pulley and simply redirects the belt to a different accessory. The other small pulley is considered a "tensioner" pulley, it is spring loaded and keeps the correct tension on the accessory belt. The tensioner pulley will have a "squared" hole in the bracket or a bolt through the center of the pulley. In either case you will use a wrench to pry the tensioner pulley arm in the direction that loosens the belt. Once tension is relieved, pull the belt off a pulley and remove the belt. You will reverse the process to install the new belt. Good luck and let me know. Regards,
remove the belt to ac compressor.take your serpentine belt go around crank pulley goes around power steering pump goes around alternator and the tensioner on the far left. the water pump on the out side and the top idler pulley out side. the belt drives them from the out side. then you put your ac compressor belt back on.
