Deleted Coolant temperature switch (A/C) = issues?

^^ Umm no, if you dont know what the heck your talking about stay away from tech questions.

If anything too much water in the coolant will actually keep temps down.

Have you tried a straight water/watter wetter combo for the summer months? That may help a bit, as well as running a 180 or lower thermostat. I ran all these combos and it still got too hot for me but you have bigger fans.
