Re: [Chrysler300] running temp

[Ray Jones <hurst300@xxxxxxxxxxx>]

Years ago, and maybe still now, the recipes on baking packages had
instructions for high elevations. This was because the pressure was loweer
above 5K feet, and it lowered the boiling point to the 190's, and changed
all the cooking characteristics.
As the operatation of modern engines changed, the need for higher temps
raised the cap pressures. The actual temp of today's engines is way higher
than the sealevel boiling point.

But the most likely culprit is the guage/sender being inaccurate, and giving
a high reading.
