if its like the peugeot 206 1.4 hdi which the engine is then it fastens to the block with 4 bolts 16mm 17mm 19mm ? If its got aircon you will have to remove the pump fisrt and drop down on the pipes to get at it,tie it up with a rope to keep the pressure off pipes .then the alternator will come out.it takes 2.5 to 3hrs to do on a 206. [do not remove aircon pipes]
