I received a Ford 302 rebuild from Engine Factory.com and was wondering about the water temperature sending unit. I see one port on the intake to screw in the temp gauge sending unit. However, I want to hook up a thermostat for the electric fan and not use one of the probe types.

Can you use a dual temp sending unit to run the gauge and thermostat? Or is it better to keep them separate with something like this?

Or is there another port on the 302 somewhere?

Thanks,

That's a neat adapter. If I had it to do over, I might go that way.
As it was, my stock 90 degree water inlet adapter at the front if the intake manifold had a boss with a depression cast into it that seemed to be made to be drilled and tapped for the sending unit. So I did it that way.
Seems like I've seen some aftermarket inlets that didn't have that boss on it. That would be a good excuse to get the egauges adapter.
It might be nice if they made one that was a combo filler/pressure cap with a sending unit port on it.
Good Luck,

My aftermarket thermostat housing came with a hole for a sender.

Some intake manifolds also have a hole into the rear crossover passage. You can use that for a fan thermostat switch. But that water is generally cooler, so you need to use a lower temp switch.

Some manifolds don't have a rear crossover. You can drill and tap a hole where the manifold meets the head at the water passage. And, don't be afraid to drill and tap a hole in the front passage.

I don't plan on removing the intake to drill/tap a new hole. Its been sealed from Enginefactory. I may just go with the adapter if I can't find another port.

Thanks,
