Yesterday, while going to work my car was not cooling even when I had my A/C, at first I thought it was a very hot day, and later I realised that it was something to do with the A/C. While coming back from work, I saw fumes/smoke coming out from under the hood. I thought it was something to do with my A/C, today while coming to work even though I did not have my A/C turned on, I still see fumes coming out from under the hood, and the car head level is at H(red). I am not sure what the problem is, can anyone advise what needs to be done, should I take it to the dealership for this, or is this which I can fix myself, please advise.

Thanks and Regards.
