If your intention is to tell the coolant temperature at the hottest place
in the engine, as near to the thermostat housing as possible should work.
If you want to tell coolant temperature in the cross flow radiator, then
your probe location will suffice.

I am in the process of hooking up a new engine water temperature gauge.
The manufacture, maxxtow, recommends to put the sending unit in the
radiator. I have the aluminum radiator and it has a port to accept the
sending
unit.
Our stock system has the sending unit in the intake manifold.

Is there a advantage in having the sending unit in the rad? Is the intake
manifold still the best location?
Or run the new gauge with the probe in the rad, and leave the stock gauge
as is?

Opinions? Recommendations?
Thanks, Scott

Thanks Jim
The rad port is right next to the water inlet uptop on the rad.

If it was yours, where would you mount it?

Thanks, scott

In your case, there shouldn't be much difference if the port is near the
top radiator hose. For me, the stock location, as well as the stock gage
works just fine. The stock gage is known to be only an approximate wild
assed guess, but that seems good enough for my needs. A high mileage 403,
well broken in, doesn't make enough heat to worry about for me. But, if you
have a tight 455 with great compression, and some head and block milling
done, your needs might be different than mine.

The main difference is what side of the thermostat do you want to be on.
Radiator/coolant temp is important but engine temp is more important.
What do you want to do if you have a stuck thermostat?
I am a data guy, I vote for both engine temp and return coolant temp.

In these days of heavy traffic, and "distracted driving incidents", I
figure that systems like the digi-panel that have visual and auditory
alerts with flashing lights and warning chimes should suffice. I am not a
proponent of gages that require that you take your eyes off the road. We
travel a great deal up and down the Interstate 5 corridor between San
Francisco, California and the Canadian border. Some of the most congested
roads most of you will ever encounter. Absolutely no place to be taking
your eyes off the road. Portland, Oregon, Olympia, Tacoma, Seattle,
Everett, Bellingham all are high speed choke points that go from 70 mph to
Zero in a hurry. Just me, your situation might differ.

Should your thermostat stuck shut, you'll not know.
