OK I put it all together and just when I thought "Success" I smelt the stench of creamy coolant and saw that my temp guage was almost in the red zone. I was driving on my way to a friends about 70 something miles away so good thing I only went a mile or so before this happened. I stopped the car in a parking lot and checked under the hood where I was greeted with smoke pouring out of the left side of the engine. I checked where the manifold gaskets were and all seemed well but then I couldnt find out where it was coming from. I looked around that black metal pipe that connects to the LIM which is just under the power steering pump and left of a rubber hose and saw coolant bubbling out of it. I knew that was the problem because that was the last thing my dad and I connected which had to be the biggest PITA ever. When I finally got it lined up with the hole and tried to slide it in the little ring gasket around it seemed pretty weak and loose after we fought with the pipe but I thought it would be ok so I just slid it on in making sure the gasket went in with it. Well Im quite certain that this gasket has now failed and needs replacing. What is this gasket called and where can I get it? This sucks really really bad and I hope I didnt ruin my engine at all by driving it home while overheating (I went as slow as possible on the rpms). Please help me as now I feel really bad and although I am extremely upset that I couldnt go out tonight I am handling it pretty well. Thanks!

Sorry I wasn't around to get this right away. No need for pics, I know exactly what you're talking about.

That'* the heater inlet pipe, and the o-ring has blown. You're going to need to remove the pipe from the car. There'* two bolts into the rear head, the black rubber hose, and the bolt into the LIM. Take the pipe to Napa and get a replacement O-ring, They should have it on the shelf. The O-ring kits in the "HELP!" box do not fit, Don't waste your money on them. Good Luck (Not that you need it)

Cool man thanks a bunch, I'll get this fixed once and for all tomorrow. Im strongly considering not getting an exhaust system as Im not sure how long my car will be holding out but if this is finally fixed with that oring and all is going well then I may get it after all.

OK other than that little problem I am also in another situation which I cant seem to figure out. On the rear fuel injector wire plugs there are also 2 other plugs at the end, one of which goes to some sort of coolant sensor that screws into the LIM and one that I have no clue where it belongs. I will try to get a picture but I figure you guys are pretty familiar with this and may be able to tell me where it goes. The Service Engine Soon light is on in my car and I feel strongly that this plug has to do with it. My dad and I looked all over and couldnt find a place to plug it in so we were maybe thinking it didnt go anywhere but I dont see why that would be. Another thing I noticed which may be related is that when I put my key into just the ON position the radiator fans turn on and stay on even when the engine isnt hot and this has never ever happened before.

That'* the engine coolant sensor plug, It'* under the Throttle Body. Very hard to see and even harder to plug in, You may even have to remove the Throttle Body.

Oh man that O-ring was torn completely in half but I couldnt get the pipe out so I just took off the gasket and am headed to Napa right now. I'll ask them first before I go browsing for gaskets. Also got that plug in the throttle body without removing it which wasnt all that hard. After this the car should be good to go.

Got it all fixed but my car is still overheating. I dont see any coolant leaking from anywhere but there is a bit of racket coming from the pulleys. Is it possible that I have the belt on wrong and maybe the water pump is being turned in the wrong direction? I dont know but I hope thats what it is because if not then well Im going to Pontiac Monday. Please help me as I will not have a Christmas this year if I have to get this fixed. Thank you all!
