Thanks again Paul. You must have about a dozen arms if you can change one of these cam belts in 2 hrs or even less, even in a properly equipped workshop! I guess this is the difference between a professional (which I assume you are) and an amateur (which I am).
As to the cam belt tension, the two I changed were on my 1996 2.0 V40 which has an automatic tensioner so tensioning it was not an issue. However I notice that myvolvoshop.com have a tensioner for this engine (see
http://www.myvolvoshop.com/Engine-Ti...uct_info.html?) for £35, probably plus p&P & vat. If it really does the job, and I'll make further enquiries before purchasing it, it may be worth the investment. I don't feel comfortable about using the "you should be able to turn it about 90°" for such a critical component.
Incidentaly, is 85Hz the format for measuring belt tension (the figure given in the Autodata specifications), I'm more familiar with x mms deflection under y kgs pressure?
