RH77 -

I have heard that 250F is the danger zone, but I'm not a car dude. I don't like my coolant to be over 210F when I am stuck in traffic. The ECU/PCM always turns on the fan at 220F. Would the detail that I have an aluminum block lower the temperature of the "danger zone" for damage?

I drive up a hill when I go home, so I use my manual fan radiator switch to cool things off as needed.
