d16z6runner

i just bought a jdm d16a and i had it installed by a friend of mine who has been working on cars for a long time but i he forgot to install a water hose that goes behind the head next to the intake manifold and he wont be back until febuary 21st and i dont want to drive it to another shop cause it already almost overheated so i dont want to drive it anymore i cant take photos of the water spiget where it is supposed to come out of and i need to know where it goes to so i put on a hose...so if its possible does anybody know where it goes or has pictures of a d16A/d16z6 motor both are the same...any help is appreciated thanks
