Hi AOrtiz, did you get the leak fixed, or at least determine where it is. If not I may have some info for you. My 99 was doing the same thing, and may still be, I changed the tube and all the hoses. Wish I would have seen your post sooner.

 

It's hard to say if I got it. I can still smell the burnt coolant smell but there is not any visible leaks and the coolant level is holding steady. So, I'm kind of at a loss.
