Hi,
I'm no expert. Did it twice already , used bucheli repair manual (in German).
- First hurdle is to get the ventilator out. A big screw-wrench and a good argument with a hammer will do
. (its free rotating so hammer will loose it using physicy - inertness..)
- loosen wheels for venti and water-pump
- loosen screws on generator wheel
- demount belt
- Loosing screws has been discussed above, for mine was no issue, just had to be careful not to damage the Torxes..
- Then: A little bit hard to get all the bolts in the holes. Dont give up until you have all them in when the old belt is still on.
Think the explanation in the "bucheli" book is best for the right order to put the bolts in. I just used drill.
First: Tricky might be to find the whole on the flywheel on the back: you have to put out the sensor, a 13mm drill fits then.
Second: camshaft gear wheel - 8mm
Third: I think 6mm for the pump wheel
- Then you have to loosen the screws on the wheel for the pump.
- demount timing belt
- when mounting, let the tensioner pulley flip in
- then turn 2 rounds and 1/4 back (crankshaft )
- test again with the bolts
good luck
