Water Temp Sending Unit - have 3 of them

[RobW33]

I'm slowly getting closer to being ready to add fluids to my 427W Crate motor. I'm just now finishing up radiator installation and came across this conundrum.


One water temp sensor on drivers side of intake manifold for EFI system
One water temp sensor on passenger side on thermostat housing for water temp gage
One water temp sensor for radiator fan relay - not sure where to install this.


Does anyone have any recommendations on where to put the third water temp sensor?

Thanks in advance,
Rob

Never mind...

The EFI system has an output to kick the fan relay on. Maybe next time I'll read the instructions first :)

There is a 3rd port available on the thermostat housing. Some factory housings may not be drilled and tapped but the port is in the casting. Autozone sells the housing with the port drilled and tapped.
