Can any one help me out, I have a 2000 Pontiac Grand AM SE 2.4 litter coupe and i'm leaking enigine coolent under the right side of my engine... It looks like its comming straight out underneath my valve and out of what looks and feels like a metal tube. There is no mix of oil at all just straight coolent, does any one have an idea what could be causing this leak?

Here's the bests pics I could get. The leak is on the driver's side, pretty much right above, and to the left, of that bolt in the pic. It is in close proximity to the heater hoses, but they are not leaking. It is not seeping - we can see a steady drip and it does not look like it's dripping along the engine block. It looks and feels like it is dripping from a metal tube which sticks out a little from the side of the block. The hoses seem to be completely dry.

Sorry, guys, but that's about as good a description as I can do. :)

Any help or ideas are most welcome.

Could the leak be coming from the water outlet housing mentioned in this post by lilred96gagt:

Awesome quick response rocketfast! I sure do appreciate it. Any advice on changing this out/any things to look out for?

Should I use RTV around the housing or threadlocker on the bolts?

It's tricky to do, also clean the area. It looks you have p/s and cam cover leak also.

Yeah, looks like the PS reservoir leaked before I got the car.

I replaced the housing. Still got a leak, but I think it's from the hose. Having lots of fun getting the clamp off the rearward side. :(

OK. Still leaking. It is leaking right @ the water outlet housing area. I replaced the hose and the water outlet housing. I also repositioned the clamps. In all the research I've done it looks like the LIM is not a factor on the 2.4. Is this right? Also, this is definitely on the DS of the engine. I can see the drip, but I just can't see exactly where the leak is even with a mirror.

ANY help or advice would be extremely appreciated.

You don't have a lower intake.

Yea still leaking, but whats your thought on it being a freeze plug and if you think it could be how hard would it be to change out?

I needed to go back in and get the o ring seated properly. If the housing was rotted out that should fix it.

It was. I'm thinking along those same lines! Maybe the little tube that goes into the water outlet housing. I'm going to try to seal that up better too.

Well, she's fixed! Thank you all for the input and advice. :) I REALLY appreciate it.

Ended up taking the water outlet housing off and using RTV around the o-ring and also around the metal tube that goes into the back of the housing. Let it sit up for 24 hours and it is good to go - no leaks!!
