Antifreeze level

Does anyone know what level I am supposed to fill the antifreeze to? I drove around a while today and it starting coming out the overflow. Granted it was a bit warm here. When it finally stopped and cooled down it is just below the baffle in the inlet. Maybe that is where it is supposed to be?

Many thanks!

As long as it stays above the tops of the tubes you are good to go. Adding a thermostat stopped my original 1928 radiator from loosing 2 to 3 quarts on a 50 mile drive.
 
With a baffle it is hard to tell how hight the water is in the radiator. If you are adding the same amount of water each time, then that is where your system is happy.
 
With mine if I can see any coolant above the baffle it is too full ---and since I can't see the level I don't bother with looking, if someone leaves a partial bottle of water in the car I dump it in the radiator whenever I clean out the car --it works out to about a quart a year.

I don't worry too much, I have taken many rides of 100 miles without opening the hood, the reliability of a stock "A" is such that I don't worry about making it home---between what is under the seat and alongside the road I will make it home.
 
I can see the overflow tube but I see no baffle? I can see to bottom of top tank , thats where it stays with a little water? what does baffle look like it is a new radiator, expensive, temp goes from 140 to 165 on 90 degree day. Am I in range is the coolant at height just above bot of tank ok? Josh
 
as a rule of thumb, if you can see that water just above the baffle your good. THEN AGAIN< the radiator will SEAK it's own level always. So if you keep filling and it keeps coming out, leave it alone for a while and see how she runs, probably fine. We have a lot of cars that are running a quart to more down and never ever overheat
 
I have 3 a,s 2 with old radiators 1 with a new alunium if you put water in to were you can see it it will push it out the overflow . In mine if you can see water it is to full.

Tom,
Are you saying a thermostat will make your car run cooler then then without one ? seems like a thermostat would restrict the flow more then without one.:confused:
 
With a thermostat restricting the flow, the water stays in the radiator longer, therefore cooling it better. Without some restriction, and with an efficient water pump, the water doesn't stay in the radiator long enough to get cool.
 
I don't know if adding the thermostat lowered the coolant temperature, but it kept the coolant in the radiator, instead of going out the overflow pipe. When I cleaned the radiator with liquid floor soap, then a final cleaning with washing soda, that lowered the coolant temp by about 20*. My original radiator had years of grease scum buildup from greasing the water pump rear bushing.
