The fan is easy to remove, it has a 13mm bolt through the middle.

Remove it and run the enigine with it off and see if the rattle has gone.

A common rattle is from the tensioner shock absorber. Its a small shock absorber that keeps the rubber belt from rattling.

Thanks for your advices.
One more clue: If I stop the engine and move the fan with my hand, no noise is produced.
I am starting to think that it doesn't come from the fan but from the distributor, that is very near to it. However, the car runs well and it hasn't been touched.

What are your impressions?

Thanks!

Re: Rattle

As Duncan suggests it is more likely to be the auxilary drive belt tentioner shock absorber. This is a common fault where the distributor is not.

OK, seems to make sense.
Is that tensioner easy to change with standard tools at home? How?
Thanks!

Re: Tensioner damper replacement

Unless my memory serves me wrong, it has a one bolt at either end and that's it. It runs from the base of the tensioner to a bracket near the crank shaft pulley.

Thanks!
So, if I have understood, the belt tensioner comprises two pieces, the tensioner itself and the shock absorber, am I right?
What's the part that most often fails? Can it be bought separately?

How can I test if my belt is not tensioned enough?

Best regards

Re: Tensioner

It will be the shock absorber that is faulty not the tensioner. To confirm it get someone to rev the engine whilst you watch the tensioner. If the shock absorber is weak, you will see the tensioner pulley vibrate as the engine accelerates.
