yes it should and it does, but it is adjustable. most car manufactures have electric fans come on anywhere between 210 most improts and 225 some domestics.

i was hoping that would be a safe #. i think i will turn it up tomorrow.
what tempature will cause a high enough system pressure for an over heat?

On at ~195º off at ~190º as measured by my autometer gauge in the block. The probe for the e-fan switch is in the radiator, though, so I don't know the exact temperature it hits when it turns on, I just set it via engine temp. It works perfectly for me. Cruising I see 180-190 degrees most the time, stop and go ~190 on average temp days, ~200 on hot days.

What's the point of that? The fan would run constantly. The fan is only supposed to run when the car isn't moving fast enough to stop temps rising. Anything below ~190degF is totally pointless.
And unless you have the wrong thermostat, it should open at 180degF.

Why bother having a thermostat switch if you set it too low?
It'll switch on and never turn off if you set it too low.
The motor runs "optimal" from 180F to 200F.
I think people get too paranoid about overheating, so they set it too low.
Your thermostat will prevent the car to cool down under 180F.
