Hi, any help would be appreciated. Does any one know how many bolts hold the starter motor in on a 2009 1.6d Berlingo van? I have got 2 out, but looking at the new unit there are 2 more threaded holes on the top which don't make sense. There is no room to get to the back of the unit whilst in situ, hoping that the whole engine doesn't have to be dropped out. Anyone thoughts? Cheers Kelvin
