UK Car Repair: fit fan belt, fit fan, renault laguna

Question
need diagram on how to put fan belt on my renault laguna diesil

Answer
I do not have access to this info but, the place you bought the belt should be able to provide a diagram.  If not, you should be able to work out the routing by matching the belt surfaces -Flat or grooved- with the pulley surfaces -also flat or grooved.  The trick is to release the automatic spring loaded tensioner.  It just takes a socket with a longish extension to turn it against the spring pressure, once the belt is on, you can then release it.
