Welcome to JustAnswer, my name is XXXXX XXXXX X'm here to help get your problem resolved. I know your not going to want to like what I have to say and I wish this wasnt the case but this means your headgasket is leaking. You do not see any white smoke because the catalytic converter and resonators clean it up. Its about a 22 hour job to have it replaced and about $600 in parts so around $3000 depending on where you go. I am sorry its not great news but I want to give you accurate information even if its not the best news. Let me know if there is anything else I can do to help or if you have more questions. If my answer is something you are just not willing to hear let me know and I can open question back up to see if someone else has ides. Please do not rate until satisfied and lower two smileys are considered negative feedback. Thanks.
Do you is safe if i drive 200 miles and keep adding coolant every 30 miles? I just want to get home.Any danger i blow the engine?
You should be ok as long as you dont let it over heat past the 3rd mark and keep adding coolant. There is no physical danger in blowing engine but running it with a blown headgasket always increases chances of blowing engine but I wouldnt worry about it. Let me know if you have any questions at all and only rate when satisfied. Thanks.

FYI....apparently you missed it and i amsurprised you did,...the problem was a rather small leak in the radiator.
I am happy to hear problem was found, usually when there is a small leak a person can smell it under hood or see a little leak on ground thats why I didnt think it was a leak. Happy to hear thats the case though, ALOT better then headgaskets. Thanks again.
