I use 265F which is the temp at which 50-50 coolant boils at normal system
pressure.  Temp normally looks fairly close to the coolant temp but at the
instant of coolant going low it goes higher VERY quickly unless the power is
pulled way back.

<br>
What limit do you set for that temp, or what temp do you see when<br>
water temp is at the limit?<br>
