Radiator overflow tank-overflows
when i drive in stop and go traffic for more than say 1/2 hour, when i park the truck, the cooling system pumps out antifreeze through the radiator overflow tank. The temp gauge never goes into the red while driving and never overheats. This has happened 3 times in the last month, but doesnt happen if i am highway driving or just ruinning short errands
After it cools down the levels appear normal.. Do I have too much coolant or is there trouble elsewhere?? Top hose is hot, so i would presume the thermostat is working

If its not overheating get a new cap and be sure to burp system several time. To remove air. This happens fairly often now that allot of our Co. trucks are 10 yrs or older and the cap ussually take care of it.. But you know Business if it isn't broke don't fix it. Good luck

when you say the temp doesn't go into the red so it doesn't overheat you may very well be missing something very important. Red means shut it down...as does close to red. Also guages don't often tell you the actual temp. So unless your guage is reading way down into the normal range and you know about what temp that represents I'd guess you are overheating.
Not sure what your driving but your cooling system is not working adequately. It could be as simple as a cap...systems that are not sealed often run borderline so that hot stop and go will be too much. But also fan shrouds and many other things could be playing a role or causing it on it's own.
Need more info on your rig before i can say much more. You do not want to run hot often as you risk head gasket and worse as time goes on. I suggest folks get an actual temp guage or an infrared hand held so that they can learn what temp the engine is running at and learn how to read the stock guage. I have both on my '79 and it helps.
