Its not leaking anywhere on the radiator like hoses or anything. Its the very top part. Any thing I can put in there I can seal it up with?

 

New radiator. Go on ebay and buy one. Real easy removal and install.

 

I thought mine was leaking from the top as well, but I tried a few things and it stopped pooling at the top (like on the right side on that little lip just below the top of the radiator on the engine side of the radiator). So I replaced the cap and I was still getting it. So I tightened up the hose that goes to the resivior and its been dry ever since. If that does not work then I guess the plastic on your radiator is cracked and it time for a new one. Even if that is the case its really easy to replace, just a little bit messy. You just take the fans off of it, take the radiator hoses off, then remove the radiator supports and then the radiator lifts out of the car.

 

if its leaking from the plastic part at the top, you can by an epoxy radiator repair kit from autozone, its lik $12 and will repair a small leak permanantly, i had a friend do this over a year and a half ago and there have been no problems with it whatsoever.
