eric - please check your radiator fan, see if it is spinning fast enough...... i had this problem with my old ride later i found out the fan was going to die......... cheers

never ever put your finger (or any part of your body..... hehehehe) around / near the fan, later you will have a part of you cut off by the fan, this happen to my cousin who is a mechanic with four finger at on hand ......... get a mechanic or a/c guy to help you check .......

worse case you may add another fan into your car .......... cheers
