Just a thought, but if you put the sensor on the exit side of the radiator
it would likely turn off once in a while. This would improve efficiency a
bit, I would think.

I

: So in a nutshell: the switch will trigger the fan at 180 (low) and 195
: (high). If engine temp triggers high it will cool until 180 and then it
: will run at low speed until 175 or so. (Mine doesn't get cool enough to
: switch off; my friend mentioned that might not be a bad thing since it's
: probably harder on the fan motor to be cycling on and off all the time

later.)

: When it triggers high it also triggers low so both of my relays are active

bench

:
: Someone had mentioned in a message I found in the archives about the fan
: runs on low when either of the wires are hot and high when both. On mine
at
: least there was a high and a low wire, orange stripe was low and yellow
was
: high. Sending power to both didn't make it run faster. Speaking of bench
: testing, make sure you secure it down somehow, mine really wanted to move
: somewhere other than where I had it laying down! Lol.
:
: Other notes: not sure if I addressed this in my first message but this
fan
: is pretty quiet. Maybe it's just my duals but it seems quieter than the
fan
: in my sister's Intrepid she had. So it is by far a lot quieter than a
stock
: engine driven fan.
:
: That's all for now.
