How To Replace the Accessory Drive Belt (Serpentine Belt) on Alfa Romeo Giulietta 1.4 MultiAir

This could apply to other cars in Fiat Chrysler group. Find the belt on the left of the engine. You can take a picture of the routing. Identify the belt tensioner by pulling on the belt and seeing which pulley yields. In my car it is the center pulley. It has a 13mm hex bolt on it. Hold it while you pull on the belt to see which way it turns as it yields. In my car it turns clockwise. I think there is a hole to lock the loosened tensioner in place, but I did not even attempt it due to difficult access. Use a ratchet and turn the tensioner with left hand and use the right hand to slide the belt from/onto the bottom pulley. It will be easier to put on a belt if it is longer rather than shorter. I got myself a rather short replacement belt and it seemed I had to turn the tensioner to the limit to put it on.

Tools used: a 1/2" ratchet with 24cm arm, a 13mm hex socket, head lamp.
