In a standard atmosphere, 43C at sea level would translate to 35C at
4000MSL.

I doubt it would be uncomfortably hot at 3-4000 feet if it's 43° C on the
ground. Maybe you're flying too close to the ground.

The difference would only be a few degrees at 4000 feet, and that's not
enough
when the temperature at the surface is 43° C. Additionally, the
temperature
inside the aircraft would be higher at all times.
