Question type: Maintenance & Repair

My 99 ml 425 screeches when I first start it, once it
is going it is quieT. What could be wrong?

1 Answer


Screeches at startup or when you rev the engine are usually caused by a belt that is slipping. This can be a worn belt or a bad belt tensioner. Check the belt, if the back side (smooth side) is shiny, you may need a new belt.
