temp questions
hey my 351 procharged stang i think is running hot.. i have aluminum radiator, two pulling fans not sure about the cfms but the temp gets up to 200 within ten mins of driving is that normal....wat is the temp that it should hang out around...i have prosport gauges.. and once it hit 190 or 200 antifreeze pisses out the over flow tank, but it isnt the right tank it is much smaller, so do u think that it is just pissing out cause the over flow tank isnt big enough... what should the temp be at normally and why could it be getting hot so fast.....thanks for the help

Pressure is the key to no damage from higher temperature. Each pound of pressure lets the temperature increase by three degrees. Water boils at 212 degrees F. Sixteen pounds of pressure adds fourtyeight degrees. Would be 261 degrees F. before boiling. Of course nobody wants to be that warm.

Yours gets that hot after 10 mins of driving? My 408 gets to 196 after 5 minutes of idling.
Put a thermostat in, that's the worst thing you can do is run without any thermostat at all, doesn't give the coolant a chance to cool down. At the very least cut the center out of the thermostat so it's at least a restriction. I have a 180 theromostat in mine, engine never gets over 200 in 35 degree weather.
I also have a small over-flow, the smallest allowed by NHRA regulations, 1 pint, never blows it out, so it won't be your overflow unless you have a pop can or something as an overflow.
Is it boiling? or just shooting it out? Grab a rad hose and see if you can feel it. If it's boiling your cooling system isn't adaquet, you're low on coolant, or you have air in the system.
