HSTuners - Engine running hot! End of story

About a year ago I was having a discussion about my temp gauge going into the red and the engine running hot on my 91 Honda Accord.. I changed every sensor, thermostat, checked for blocked hoses and radiator, nothing worked. Had to put the heater on hot to cool down the engine and get my gauge back to normal, that was a hot summer.

Turned out when I pulled my radiator all the bottom fins had corroded away. You couldn't see this from looking at it as the fans hid the spots. Put in a new rad for less than $200 Cad, it took only an hour and the gauge is back to normal. Thought you might like to know the end result in case you have the same problem. Closely inspect the radiator before changing sensors !!

Thanks to John on this board who pointed me in this direction.
