Car getting real hot....

Need to know what kind of fan set up you have. I bought a 66 cuda out of arizona once with a/c it would heat up like you are experiencing , drove me nuts until i stuck my head to adjust the carb and noticed all the air the fan was generating was going straight up- not back towards the engine. I took a look at the fan and some genius flattened out the blades to clear the compressor- this was a slant 6 car so the compressor was lower than a v8 car.

Definitely get a thermal gun too I have had the gauges read wrong too. They sell them at harbor freight for cheap
