OVERHEATING caused by coolant leak?

[Alex2wonderland]

So my car started overheating and we thought maybe was leaking coolant. So we filled it back up and I drove it to work (maybe 2 miles away) and then it overheated again and when I popped the hood, the place where my coolant goes (I'm assuming the reservoir) is cracked all the way from the lid down the whole side and coolant just poured out.. What could be causing this? Expensive? We already changed out the thermostat after the first time it overheated.

ANY HELP WOULD BE SO GREATLY APPRECIATED!

would suggest that you post just in one section
also helps to know year model engine information

Plastic tanks are known to split, replace and move on. Once the new one is on have it pressure tested with the engine running to make sure there aren't additional problems.
