Re: [Chrysler300] running temp

["Charlie Valentine" <cross.ram@xxxxxxxxxxx>]

While not an expert by any means, let me add what I think I know.

If I remember correctly, from what I read in a STANT cooling manual, the
lower the pound on the pressure cap the lower the boiling point. And vice
versa. So if you are running a 7 pound cap to keep down the pressure the
boiling point is lower and boil over may happen easier. Not sure how using
the lower pressure cap relates to the actual engine temperature. The STANT
book may have related that but just do not recall.

Like I said I am not an expert so please, and I know someone will, correct
me if I am wrong.

Happy 300ing
Charlie Valentine

Tim;
It sounds fairly normal. You might want to check your guage against another
thermometer. Use a big kitchen thermometer, like you stick in a roast, and
leave it in the fill hole of the rad while the car warms up. Then keep
checking it against the dash guage to see if they are in the same range.
Dash guages are "more or less" accurate, and are mostly for general
referance only. They are not exact scientific guages.

The purpose of Anti-freexe is as much to raise the boiling point of the
water in the system as it is to lower the freezing point. That, along with a
12-14# cap keeps the water from boiling at 212. With the higher pressure,
the boil point is raised to about 240, and the engine runs at a "normal" 220
degrees. This is why you never open the cap on a hot engine, the release of
pressure instantly allows the 215-220 degree water to boil.

Enjoy, Ray
