A cambelt kit - part number 7701474019 is £120.00 + vat and an auxilary belt is £15.99 + vat part number 8200226493. The labour rate with Renault is 2.7 hours to do both belts ( £45 - £70 per hour depending on dealer ) When you fit a timing belt it is essential that you fit new pulleys as well, as the pulleys are made of plastic and if there not renewed they will eventually collapse causing mass damage - the equivalent of a snapped cambelt. Always change the auxilary belt as well as if this snaps they have been known to become entangled in the cambelt and cause the cambelt to jump, again causing massive damage to your engine
