I was working on a 280Z and had a thermometer sitting on the windshield wiper outside in the sun (where I did triage). It was a cooling system thermometer and read 160 degrees when I noticed it. Thermostat opening temperature was 180.
I drove home yesterday in 95 temps and left the ac off, had a little wet spot where the shoulder harness was riding on the right side of my chest. My shop was air conditioned, not good enough to get it below 85 on hot days, but the lower humidity was almost as important as the temperature. 99 degrees with 99% humidity is worse than 120 with 10%.
A long time ago I worked in a shop that had a flat tar covered roof. It got so hot the tar would melt and drip through the roof down onto your hair, which you then ripped out.
I wore shop rags soaked in water fountain water to keep my brain from overheating wrapped around each arm at the shoulder.
