hi you have 2 options here!
first if it the diesel 1.5 dci they are on about the crank locking tool that goes through the casing and locks the crank in the correct position.
The petrol models use the same but also the cams have a tool too!
the job can be done with out these tools very easly i would take it to a garage that will do it with out the tools .There are mechanics out there that will do the job by making there own timing marks or using there own methods
secondly
These tools you need are abt £40 on ebay do a search for renault timing tool and look through for the 1 thats for your engine *-) cheaper than stealership prices!!!!!
