951 Timing belt

Just wondering if the 88 951 has the auto belt tensioner or not. I remember seeing something about the later models having this, so does it?

Yes, from '87 the timing belt has a automatic adjusting tensioner.
Note that you still have to do the 2000-2500 mile retension and ou'll need the guage to check the balance shaft belt. I would also check the timing belt anyway with a guage as the auto-tensioners are'nt always accurate.

Why do they call it an "automatic" belt tensioner when you have to loosen the bolts on the tensioner so it can reset the tension and then tighten them again? When I think "automatic" I envision something more like the 968 tensioner I guess.

It automaticly 'sets' the tension.
It doesnt automaticly 'maintain' the tension.

When was the last time you changed your timing and balance belts and/or cam chain and tensioner?
