Does anyone know how to identify which component is which when you’re looking at the engine? I’m kind of lost!

That’s a common issue! The alternator is usually located on the front driver’s side and might have a thick wire connected to it. The power steering pump will be near it, often painted black. The A/C compressor is more towards the front of the engine as well. Good luck!

I had to replace my serpentine belt recently. The whole process was a bit of a puzzle, but seeing the components made my understanding better! Just be careful not to get grease on your hands—what a mess! :joy:

That sounds like quite the experience! It’s good to hear that identifying the components makes it easier. For my 2004 Grand Prix, I found that the belt tensioner also plays a key role. Keep an eye on it too!

Right! The tensioner keeps the belt taut. If it’s worn out, it might cause slippage and affect the other components. It’s worth checking when you do the belt.
