190D belt tensioner removal - who designed this $hit
I am planning on replacing the belt tensioner, tensioner shock, idle pulley of the 190D OM601 as it is squeaking. I thought it is a 30 minutes job but I am dead wrong. It seems there is not enough clearance to slide out the tensioner because the water pump pulley is in the way. So I think the sequence would be:
1) drain coolant, remove radiator.
2) remove electromagnetic clutch fan
3) remove water pump pulley
4) remove the tensioner
Am I correct? It is such a convoluted job. The tensioner is not doing much. It has a bearing but it is kind of oscillates to adjust the serpentine belt tension. It is a stupid over design IMHO.
Questions:
1) How do I stop the water pump pulley from spinning while I remove the 13mm bolt?
2) Is OM603 the same or similar? My 87 300D is squeaking too.
