I swear... I've tried everything!! I cannot get the coolant to stop leaking from the gooseneck!!

I've had problems with this car overheating from time-to-time since I bought it... the one thing that really aggrivates me. I've replaced everything except for the water pump (which is fine). I seem to have a problem with the coolant leaking from the around the gooseneck. I've tried replaced the gasket and thermostat. I've tried a new gooseneck. I've even tried getting the gasket maker goop and applying it - still, I cannot get it to stop overheating.

Help? I don't know what to try next...

 

Is the mating\sealing surface on the manifold level? Is the coolant possibly coming up through the threaded holes in the manifold.Has the mating surface corroded, leaving no mating\sealing surface?Was the replacement gooseneck level across the bottom?Are there any cracks around the mating surface? Are you overtightening when the sealer is wet it acts as a lubriucant to push out the gasket if you do both at the same time and over torque it. Tried putting on a dry gasket and torquing to spec?

 

The # 1 cause for third gens to over heat is the air dam under the car. Most are missing, or broke, or whatever, and simply replacing this will solve all issues. A friend from this board said he bought a camaro at a discount price from a local dealer because they couldnt get it to stop overheating, ect, they replaced everything and still nothing. He took it home, put on a air dam, and worked fine from there on out... You didnt mention it in your post, so i thought i might add my .02 in case you also overlooked this.

Hope it helps...

 

when i replaced my t-stat i got a tiny crack in the gooseneck, and it leaked fluid, i'd look and double check where its coming from, amke sure there isn't a tiny crack in it

 

 

Yep my parents drove mine for four years with overheating problems then last year i came to this site and found the simple 27 dollar answer

 

Its amazing what a new air dam can do. My old one was two inches shorther due to wear, and the car now runs 20* cooler.

 

Its also amazing this isnt a sticky... Mods.. you should sticky this, or make a variation... Good knowledge, and alot of people overlook this simple but important issue on the Third Gens...

Thanks

 

One of my *technicians* had a similar problem once, after replacing a thermostat housing. I found out that the new housing was not as thick as the old one. I had to use shorter bolts because the old ones were too long, and not tightening down.
Best way to check is to make sure the bolts actually tighten down w/o the housing in place. Aside from that, make sure the mating surface of the intake and housing are clean like someone else mentioned, and use RTV on the bolts, threads, and washers. I have also heard good things about the newer o-ring seal type.
