1. Park your vehicle on a level surface.
2. Turn off the engine and allow it to cool down.
3. Open the hood of your vehicle.
4. Locate the serpentine belt, which is the long belt that runs around the front of the engine.
5. Find the serpentine belt tensioner, which is a pulley with a spring-loaded mechanism. It is usually located near the top of the engine.
6. Use a wrench to turn the tensioner pulley counterclockwise to loosen the belt.
7. Once the belt is loose, use a pry bar to pry the tensioner pulley away from the belt.
8. Slip the new belt over the pulleys, starting with the crankshaft pulley and working your way around the engine.
9. Once the belt is in place, use the pry bar to release the tensioner pulley and allow it to spring back into place.
10. Tighten the tensioner pulley bolt to secure the belt.
11. Close the hood of your vehicle and start the engine.
If the squeaking noise persists, it is possible that the water pump is failing. To check the water pump, you can inspect the area around the water pump for signs of leakage, such as coolant dripping from the pump housing or a visible water trail. You can also listen for a grinding or squeaking noise coming from the water pump area. If you suspect the water pump is failing, it is best to have it inspected and replaced by a mechanic.
