Default Coolant Leak (Major?)

Okay, so I was reading a post on here saying that taking the engine cover off will allow it to run cooler, so I decided after filling up today to pop the hood and just take it off. So I do so and what do I find? A Coolant leak. The reservoir is more than full so I assume it isn't too bad. I'm a dunce when it comes to engines (unfortunately), i took some pics but its hard to see. I have green coolant so you can kind of see it pooling around the injectors. Its running no better/worse than usual. Any thoughts?

Not sure on the leak..... but if you clean things up under the hood you might be able to see where it'* coming from better.

If it'* pooling around the injectors I would suspect your Intake gasket. It'* pretty common on these cars (I had to fix mine just a few months back).
Clean the engine up as best you can to remove the water & keep a good eye on it for a few days. If it re appears again in the same place count on replacing them.
Also check your oil to make sure no water has gotten into it. It will appear milky after running if any has. If the leak has managed to find it way into the oil stop driving the car & get it fixed or you run the risk of washing out the bearings.

Yeah, I realize its pretty dirty. Never stays clean for long. Anyone wanna ballpark how much the LIM is?

I think I ended up spending around 50 bucks for everything when I done mine. You will need the Lower intake gaskets, as well as the SC/LIM gasket.
If your doing the work yourself, depending on your skills look at a minimum of a couple hours to change everything.

Unfortunately, when it comes to engine work my skills are nonexistent. My step brother would be able to do it, but I'll prolly just go to a shop.

I dipped a paper towel down in the screwholes to see for sure what kind of fluid I had. It was a mix of oil and Dex (...you mentioned green?). My LIM gasket was leaking with the UIM close to it.

IF it is determined to be UIM/LIM leak... The cost of the gasket kits (both UIM and LIM), oil/filter (yes, you'll need an oil change), and new coolant (what do you have? Good time to put in something OTHER than Dex) was only $100...it cost me $350 in labor. It'* about an 8 hour job if you're going to be billed for time. Of course if it'* a buddy, perhaps a case of beer will suffice.

Best $450 I ever spent though. Driving it with a leak is like sitting on a grenade with no pin....you know it'll blow, you just don't know when.

Yeah, I've already switched from Dex last year. And I spread the word that Dex is evil. Frankly, I've got quite a few problems with this motor. I've got some serious thinking to do. I'll have to really look into it tomorrow with my step brother. But I agree, its self-destruct if I don't get it taken care of. Thanks for the info.

Try reading this! If your LIM or gaskets are going you'll probably see something similar.

My leak must be in the very early stages as the resevoir is completely full. I'm gonna take it to a mechanic tomorrow to find out whats going on exactly.
