water leak

Hey guys, on my 95 200sx turbo, I tapped into water lines at the heater hoses, and they have been leaking slowly for a while. Last night on the way home from work my car started overheating. By the time I got home the temp gauge was all the way up and there was steam coming out from under the hood.

So this morning I fixed my heater hoses, and when I went to put water in there was a new leak. It seems to be coming from around the middle of the intake manifold area. It is a fairly quick leak, bad enough that I can't drive the car with the leak. I have no idea where it is coming from.

Is there a freeze plug or another coolant line back there somewhere? or something else that could cause that kind of leak?

You'll learn to absolutely hate the cooling system on the GA16DE. There are several hoses that have random positioning points on the engine. Follow the feed hose to the water pump (the one that wraps around the backside of the engine). There should be a hose between the metal pipe and thermostat housing. Check that hose for leaks. There is also a smaller hose that runs from the thermostat housing to the lower intake manifold. It is also prone to leaking, and is a real pain to remove and replace. Don't forget about the throttle-body hoses for cold weather start-up as well. These hoses are the biggest flaw I have found in the GA16DE... whichever Nissan engineer designed it needs to be flogged a few times.
The smaller hose that runs to the lower intake manifold sounds pretty close to my problem. What is the easiest way to get to it to change it?
There is no easy way to do it. You'll probably need to remove your oil filter, intake manifold support bar, and then try for it. On my car, with my oil feed line coming off the oil pressure sender, it is almost impossible to get to. You might have better luck if you have a sandwich plate for turbo oil supply, since that can be pulled off fairly easy.
