How do you change a fan belt on a Renault scenic?

Answer 1

8 valves or 16 Valves?

Basically locate the tensioner which is a round black plastic pulley, it should have a 13mm bolt through the middle of which, and an Allen key hole aswell? This hole may also be in the form of a torx ?

There are so many difference types of engine it would be difficult to explain all of them.

On some tensioners you must put your 13mm (long) spanner onto the bolt and lever it toward yourself (from front of vehicle), this will allow slack on the belt, don't let go, have your assistant pull the belt off whilst you hold the tensioner off.

Then simply refit the belt / fit a new one.Dont forget the way it is routed, i.e draw picture of how the belt sits around each pulley.
