Hello
Knowing the french cars I think its a pain to replace, I did it on a megane and it wasnt very pleasant. I dont know where its located but more than likely its more accesible from under one of the front wings, I would take the mudguard off and see where the locating nuts are, then remove them along with water pipe and electrc connection. Do the reverse to refir
Also be carefull if it has water you may get a little wet
