Replacing the Serpentine Belt

Replacing the serpentine belt on your Mercedes C230 can be done with some basic tools and a little mechanical knowledge. Here’s a step-by-step guide:

1. Gather Tools and Materials:

- New serpentine belt

- 17mm socket and ratchet

- Torque wrench (if necessary)

- Safety gloves

2. Preparation:

- Park your vehicle on a flat surface and turn off the engine.

- Allow the engine to cool completely.

3. Accessing the Belt:

- Open the hood and locate the serpentine belt at the front of the engine.

- Identify the tensioner pulley, which will need to be released to remove the old belt.

4. Release Tension:

- Use a ratchet with a 17mm socket to turn the tensioner counterclockwise. This will relieve tension on the belt.

- Once tension is released, carefully slide the old belt off all pulleys.

5. Install New Belt:

- Referencing your earlier diagram or photo, route the new serpentine belt over each pulley as indicated.

- Ensure that it is seated properly on all pulleys.

6. Reapply Tension:

- Again, use your ratchet to pull the tensioner counterclockwise and slip the new belt over it.

- Slowly release the tensioner to apply tension to the new belt.

7. Final Checks:

- Double-check that the belt is correctly aligned and seated on all pulleys.

- Start your engine and observe for any unusual noises or issues.
