2004 hyundai elantra.. car had coolant leak the other day and temp gauge went past red lines. Leaking out the passenger side front of car, round piece with hole in it.. bf put stopleak in it and filled...
Let's go over a list of things here and get everything organized. Most cars have an "open" coolant system, meaning that if it gets too hot (thus increasing the pressure inside the coolant system), the reservoir or radiator cap will open up and allow that pressure to release, or the coolant to expel - which would cause you to spill coolant.
After it cooled down, you were able to drive it for 70 miles - presumably on the highway/interstate/freeway, or another road that may not have a whole lot of stopping.
Then you started driving in town, most likely with stoplights or stop signs. The car overheated then and you weren't able to get it restarted (which is normal and is a safety feature on a lot of cars).
Fluids are good, the fan is kicking on, and the belts haven't broken.
Okay, so you actually did a pretty good job narrowing this down (assuming I didn't miss anything). The car is doing it's overheating when you're in stop and go traffic, with low airflow. If you are running your air conditioning, try turning it off and see if that keeps you from overheating (assuming the car starts now). If it does, then chances are your fan isn't kicking into high-speed. On some vehicles, you have two fans, on others you only have one. If you have two fans, one will only kick on when the AC is running. If you have one fan, it should have two speeds. A low-speed for simply cooling the engine, and a high-speed for when the AC is running.
If you don't overheat when the AC is running, check your relay box under the hood and search for a relay that should be labeled something along the lines of "Fan 2", "Fan High", "Fan AUX", or "Fan AC". If you find one, replace it or try switching it with another relay. Good luck!
