![]() Reattach clamp and tighten, plug in vacuum and electrical connections. Relocate the air box (good time to clean it out first) and secure it with the 10mm bolt. Torque the 18mm to 85ft-lbs and then torque the 15mm bolts to 45ft-lbs. Lower the engine until the mount rest over the studs and the 18mm nuts can be tightened. Once complete, place the engine mount back on and tighten the 3 15mm bolts. Be sure the belt is tracked appropriately. Now you can use a 3/8 wrench on the tension pulley to remove the old belt and place a new belt on. Loosen and remove the 3 15mm bolts and remove the engine mount. Jack the engine up just before the mount clears the studs where the 18mm nuts were. Loosen and remove the 18mm nuts from the engine mount. ![]() Place a floor jack under the engine to support it. 2010 CHEVROLET EQUINOX Replacement Belt Year 2010 Manufacturer CHEVROLET Model EQUINOX Engine 2.4 Liter Specific Details SERPENTINE BELT OEM Part Number 12634319 Belt Type K Micro V VBG Replacement Id 8UT0136013 Technical Specifications: (Inches) (mm) Outside Circumference 41.25 1047.75 Top Width 0.7 17. Remove the single 10mm bolt from the air box, and loosen the clam screw from engine side unplug vacuum line and any other electrical connections if you want to remove it completely. You'll need a torque wrench to torque the 15mm bolts to 45ft-lbs and the 18mm bolts to 85ft-lbs when finishing. Another way is to draw a routing diagram before removing the old belt.All you need is a floor jack, flat screw driver, 10mm, 15mm, 18mm socket. For some cars, the routing is shown in the owner's manual. To replace a serpentine belt, you will need a belt diagram that shows the routing. 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? Replacing a serpentine belt costs $18-$75 part plus $50-$150 labor. It's also a good idea to replace an old serpentine belt before a long road trip. If your car has two belts, we recommend replacing both at the same time, because you are saving on labor. A serpentine belt must also be replaced if it is found to be soaked in oil or stretched. In most cases, it's easy to see when the belt is worn out. When you take your car for a regular oil change service, a mechanic will look for cracks (see the photo), splits, damaged edges, missing chunks, glazing and other signs of wear. 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. ![]() A serpentine belt runs on several pulleys. This caused the belt to squeal and wear faster.Ħ. The alternator in this photo is not lined up with the belt and other pulleys.
