I have the Bentley service manual and cannot find this information anywhere. I know the drive belt tensioner bolt has to be torqued and then +90 degrees. Is it available in the manual somewhere? I've gotten information on some forums but want to be sure before installing.
Nowhere in factory info can I find the spec for the idler pulley, but the idler pulley on the alternator is spec'd at 40 Nm or (~30 ft-lb). Need to look into it further, but wanted to get something out to you. Does that seem right to you?
