Didn't read your reply all the way through
No I don't agree
about the cycling. What didfference does it make how high the temp is, heat cycle is aheat cycle. The amount the part is designed to take is relative to the task it's meant to perform. When you shut off your water pump your pump loses it's ability to carry away the heat generated right after power off. The pump relies on water flow to cool it, at shut down it's still up to full temp.
The last reply I agree with the you about the pump being on when the comps turned on, that's what I meant by a "failsafe"
