While waiting in a vehicle line idling for about 45 minutes (for the city dump) car started running hot, 230 degrees, AC working poorly, barely cooling the air. I turned off ac. Slowly cooled back to normal 210. New cooling system, always runs 210 no matter what. AC can freeze a side of beef (Except today) While waiting in line there was a tail wind about 30-35 mph. Ambient temps were 90 degrees, but my mirror indicated ambient temps at 116 degrees. Odd, as it is usually within 3 degrees even idling. As soon as I turned left into the dump (still in line) I had to roll up the windows as the dust/smell from the front loader moving garbage was awful. So I turned the AC back on and it worked perfect again, cold AC, normal temps. So do you think the tail wind was negating the airflow from the cooling fan causing these issues? Sounds like it to me. The wind was blowing directly behind me, and as soon as I turned perpendicular to the wind, vehicle was working like usual.
