hey guys been a while since i posted but ive put the golf back on the road after insurance was just a b****
ive been driving it around and have noticed im loosing water everyday
having to fill up a whole bottle of coke (water) everyday
and only yesterday i noticed this

any ideas of what im supposed to look for? is it still safe to drive?
its not over heating at any point unless im sitting in traffic and even then it only comes up to optimal temp!
any help much appreciated guys
