Alternator Replacement Instructions?
I have a 2007 SL55 AMG that I need to replace the Alternator on. Would anyone by chance have any good resources or instructions on how to do? I have done quite a bit of research online, but haven't come across anything that is definitive in its procedures and could use some assistance. Thank you for any and all assistance.
Here are the current instructions that I have noted: Is anyone able to comment on the validity of these?
1. Disconnect battery ground cable.
2. Remove engine front cover.
3. Remove both engine air intake ducts from air filter housing.
4. If drive belts are to be reused, mark direction of rotation.
5. Rotate belt tensioner arm counterclockwise, using a suitable tool to relieve tension from supercharger drive belt.
6. Lock tensioner in release position, using a suitable drift or punch.
7. Remove supercharger drive belt.
8. Rotate belt tensioner pulley counterclockwise, using a suitable tool to relieve tension from alternator drive belt.
9. Lock tensioner in release position, using a suitable drift or punch.
10. Remove alternator drive belt.
11. Raise and support vehicle.
12. Remove center engine compartment sound insulator panels.
13. Remove protective cap and disconnect connector for circuit 30 (B+) on alternator.
14. Disconnect connector for circuit 61 (D+) on alternator.
15. Remove alternator bolts and alternator.
16. Reverse procedure to install, noting the following:
a. Torque alternator mounting bolts to 33 ft. lbs.
b. Torque B+ wire nut to 13 ft. lbs.

Thanks for the reply @Plutoe - Such as this? When you say you can purchase on ebay, are you referencing something like this?
