I need to replace the alternator on my 1989 300E I was wondering what i need to do in regards to the belt how do I loosen it or do I even need to. Can i find this on braingears? Thank you for any help

 

Are you sure you need to replace the alternator.
A charging problem????. You can buy the the voltage regulator and the brush set for about $30..
All you need is a simple screw driver and 10 minutes of your time.
This will solve 95% of all alternator problems.

 

The car runs dut after a few feet power cuts out and it will not restart until jumped. The same thing occured with my mothers 300E and after the mechanic replaced the battery and alternator it has not happened since. What you are saying is should they just tried to clean and replace the brushes first? Thank you for your help.

 

Thank you very much for the help replacing the voltage regulator did the trick and saved me a couple hundred. Your advice was much appreciated, It runs perfectly now.
