hello all i have a 03 citroen c3, and when i was filling up my windsreen washer bottle i noticed a leak of fluid coming from the left of the engine its the part thats attached to the main engine on a bracket to the left its metal and has a black rubber seal all the way round with a small sqare part that goes in and seems to be leaking fluid, sorry i dont know the part name but i know nothing about cars. is it meant to do this or does it need replacing. any help would be great, thanks for your time. <_<
