Volvo Repair: timing belt, intermediate shaft, minute job

Question
1985 760 turbo  I NEVER DID ONE ON A VOVLO, DO I NEED A TOOL FOR BELT TENSIONER AND WHERE ARE THE MARKING ON THE CRANKSHAFT

Answer
John, this is a 10 minute job.  No tool needed for belt tensioner.  Just a pry bar to push it back. Mark on the crank is a slit on the fron spacer and then there is a line on the crankseal cover.  Cam is about 12 oclock and intermediate shaft is at about 3 o'clock.  Roger
