Leaking coolant system

[grandprix104]

ok the Prix decide it didnt think the new alt i just put in it was enough attention so it sprung a coolant leak. It isnt too terribly fast, leaves no puddles but there is no water in the oil either so i dont know what the hell its doing. There is no trace of water leakage anywhere. Just wondering if you guys had seen anything like this and if you know of any common leak areas, thanks!

Freeze plugs, water pump seals, and external head gasket leaks, hose clamps

Intake manifold seals have been known to go on the 3.1 motors.

And yours is a 94, and they had the manifold problem more often since it was the 3100's first year.

Is it running hot? Closed t-stat and it will overflow while you're driving and you might not notice it. Happened to our van for a while.

radiator cap, they can get hot and the gasket can leak antifreeze outta the rad.

if it leaks out of any of those places there will be white crud around the leak.

[grandprix104]

ok well thats some more things to check around. As for the t-stat and rad cap they are both brand new.

[White93z34]

what about the metal heater lines those love to rust through.

a way to test and see if a t-stat is working is put it in a boiling pot of water if it opens it works i've heard of some new ones not working properly :? could that be the problem possiablely?
