Ford Mustang: New temp gauges DO work!!

Agreed.
 

This is what confused me! The movement between 1/2 and 3/4 and back
was very smooth, and took several minutes. It appears that it locks
at 1/2 way for a "safe zone" of temperatures, say 185-210 or something.
Interesting though.

Did ya get stuck in that @#$%@ backup before Stateline coming from
California ?

I was in that this past friday for 2 1/2 hours ! I wasn't as worried about
temps as I was about GAS ! I practically coasted into Buffalo Bills !

From the Ford Service DVD for a 2001 Mustang:

"Engine Coolant Temperature Gauge

"Engine coolant temperature information is received by the instrument
cluster from the PCM over the SCP network. Engine coolant temperatures
above 121°C (250°F) will cause the gauge to indicate above the normal
band. If the engine coolant temperature information is missing or
invalid for five seconds, the temperature gauge will indicate below the
cold (C) position."

From a truck Service Manual -

"Temperature Gauge

"The PCM receives the engine coolant temperature status through
hardwired circuitry to the engine coolant temperature (ECT) sensor. The
instrument cluster receives the engine coolant temperature data from the
PCM through the SCP communication network. The instrument cluster
microprocessor monitors the engine coolant temperature data received
from the PCM and commands the temperature gauge indication with a
corresponding movement of the pointer."

Wow, that seems a bit high. Isn't 250 usually in the red for most cars?

obviously the trucks don't get the idiot gauge that the Mustangs get.

As far as I can tell, the temperature gauge on my 2003 Exxpedition acts
exactly like the one on my 2001 Mustang. The statements in the manual are a
little different, but I believe the result is the same. If the temperature is
"normal" (as defined by Ford), the gauge moves to the middle of the range.
When it is cold it is at C, when the truck reaches the "normal" temperature,
the gauge moves gradually to the middle. I've never seen either the Mustang or
the Expedition move higher than the middle - even though the Mustang will turn
the cooling fan off and on which indicates a changing temperature.
