To get your air box up and off, there's a little safety clamp here that you'll want to remove carefully. Now there are a couple of clips you just pull off with your thumbs. ![]() What I found actually is you only need to loosen up the clamp that's on the engine side or closer to the engine, and then you pull the tube off the engine. You just take a little tab, move it to the side, pull that off, and then there's two clamps to loosen. To get to it, you have to remove the intake tube, which is not too difficult. Tools you'll need are a flat blade screwdriver, 10mm, 15mm, and 18mm socket with ratchets and extensions, and a 3/8"� drive ratchet or flex handle. It's pretty easy once you get the parts out of the way such as the air box and the engine mount. It's the same as any Equinox with a 3.4-liter, and it's also the same on the Torrent.

I hope this how-to video helps you out, and next time you need parts for your vehicle, think of. Another way is to draw a routing diagram before removing the old belt.Brought to you by, your source for quality replacement parts and the best service on the Internet.

On the scale from 1 (easy) to 10 (leave it to pros) the serpentine belt replacement can be rated from 3 to 7 depending on the car. How easy is it to replace a serpentine belt DIY?

This serpentine belt shows cracks, it needs to be replaced When a serpentine belt needs to be replaced Replacing an A/C compressor or alternator could cost from $450 to $850. If it's just an idler, it's not very expensive: $15-$35 for the part plus $60-$170 labor. The repair will depend on what part is bad. A mechanic might have to remove a belt and check the devices that are run by a belt one by one. A bad bearing inside the alternator, A/C compressor or power steering pump produces the same type of noise. Mechanics use a special stethoscope to look for the source of noise. Because several belt-driven devices can make a similar noise, this one might take some time to diagnose. When that bearing goes bad, it can produce a whining/whirring or screeching noise. To route a serpentine belt, many cars use free-spinning pulleys like the one in the photo. The fix, in this case, was to replace the belt and worn-out alternator bolts to align the alternator.Ī failed bearing in one of the idler pulleys like this one is another common source of the noise.ħ. ![]() If you look closer in the photo, you can see rubber shavings in the area between the belt and the alternator. This caused the alternator pulley to be misaligned with the belt, so the belt was squealing and wearing out faster. Upon closer inspection, we found that the alternator was loose and shifted under angle. For example, in this car, in the photo, an alternator and a belt have been replaced while on a trip, a few weeks ago. Sometimes, you can visually see when one of the pulleys is not lined up. One of the symptoms of this problem is increased wear on one side of the belt. Often this problem is discovered after a newly replaced belt still squeals or wears out fast. ![]() If any of the belt-driven devices or a tensioner pulley for some reason is not lined up with the belt, the belt will squeal.
