Re: {Chrysler 300} coolant level down

One other thought, generally an overfilled system will spit after shutdown when the water stops moving and temps spike. James, are you seeing this when you park? Or are you seeing evidence from the end of the overflow tube?

I want to chime in and completely concur with the self leveling comment made by Bob.

I have a bunch of these. Every winter I go thru check all of the fluid levels/change fluids/air pressure etc… every spring they all spit out what they don’t need - so I learned years ago- don’t sweat it as long as tubes are covered & the temp gauge is reading Ok. And even then every once in a while I drag out my old school meat thermometer and double check the temperature gauge if I’m suspicious.

Needs room to expand when hot.

That's why they added the

Coolant recovery system

In 1973 on all models.

My 300F acts the same way. It wants to be about a quarter inch over the tubes when cold. Any more than that it will push out the extra when I stop. Done it at cruise nights and car shows more than once. The car never runs hot.

On my 64, the radiator coolant level seems to drop to hear the bottom of the upper tank. No leak in the radiator or anyplace else I can find. I noted that it seems to push water out the overflow after a long hour freeway run. I am used to this in my cars without overflow containers, but never this much.

Is it possible that the pressure cap is not doing its job. Anyone having issues with the pressure caps?
