[s-cars] Timing belt tension

[Robert Rossato]

Good point.  The Bentley manual just states to twist it 90deg, but whining is definitely a sign of being too tight and should be part of the mix in "measuring" the belt tightness.  It's a good way to take some of the subjectivity out of it.  If you can easily twist beyond the 90deg it would definitely be too loose.
