This thread makes me curious about temperature gauge sending unit location. Ford, on my '75 block, placed the temp sending unit location as being on passenger side, near top of #5 cylinder.
I've read some members prefer to locate it in radiator, or in the thermo housing, so they know the temp of heated water leaving block--the hottest area in the cooling system. That temp runs 20* higher than running temp in block.
I assume the oem location is best. Any opinions?

2-3 mpg better, less oil usage between changes, and most importantly, runs a ton smoother in town, where it always ran super cool n stuttered with the 180. I really enjoy the quick, hot heat on frosty mornings.

The ecm needs the hotter tstat , otherwise the system will never get to closed loop and run optimally.
The coolant temp switch is commonly referred to the "master sensor" and on these engines it's located at the thermostat housing, the best indicator of how hot the engine is running.
