Feb 13, 2024 · This weekend we replaced both the belt and the tensioner with Genuine GM parts. Replacing the belt is quite fast and easy...if you have the correct tools.
Our 2013 Buick Lacrosse 2.4L hybrid eAssist had a brief chirping noise as the hybrid-charging engaged (when braking at higher speeds).
In December, we did a 4-wheel brake job as they were worn out. But the chirp continued. The chirp sounded like it came from the belt area. So we cleaned the...

I need the diagram for the car listed above, police package. Reply 1: Hi, As far as the belt routing, I attached a pic below from the manual. Let me...
Some vehicles have the serpentine belt diagram located on a decal somewhere in the engine compartment. But if your car does not have a decal, you can easily look up the diagram in a repair manual or repair database. Another option is to take a photo of the old belt before removal.
A: Commonly a belt routing diagram sticker is on the underside of the hood or in the engine compartment. If there is no diagram, make a sketch of the belt and pulleys before removing the belt.
Turn off the engine and remove the serpentine belt. Shake and spin each pulley to check if there is excessive play or noise. Any play or back-and-forth movement indicates a bad pulley bearing.
This industry standard number, frequently denoted as the “PK” number, is printed next to the manufacturer's part number on almost every serpentine belt produced, and can be seen in the examples below. WHAT IS A “PK” NUMBER? A “PK” number is a worldwide standard metric belt measurement printed on most serpentine belts.
The serpentine belt is a single, continuous belt that drives multiple components like the alternator, power steering pump, water pump, and of course, the air conditioning compressor.
The timing belt is inside the engine and keeps the crankshaft and camshaft in sync. It ensures that the engine intake and exhaust valves open and close in time with the pistons so the engine runs smoothly. The serpentine belt is what keeps the engine accessories running smoothly and efficiently.
We suggest technicians change a pulley whenever a timing belt or serpentine belt is changed and vice versa, but there are eight key warning signs to look out for when a pulley goes bad: Rock – Rock the pulley back and forth. There should be no movement or play from side to side.
The tensioner pulley is responsible for keeping the belt tense while making sure it stays aligned the entire time you're driving. While the location of the tensioner pulley can vary depending on the vehicle, you can usually find it at the end of the tensioner, which is typically connected to the accessory drive belt.
Check if the belt runs centrally on the pulleys. Any sideward movement or slippage can indicate misalignment. Straightedge or String Line: Place a straightedge or taut string along the faces of the pulleys to see if they line up perfectly. Any deviation from a straight line suggests angular or parallel misalignment.
You can find the correct size of serpentine belt for your car in the owner's manual or by using an online belt sizing tool. If you are unsure about the size of the serpentine belt you need, it is best to consult a mechanic or an auto parts store.
