ok on my 2.5 shadow if your driving down the road at a steady speed it stays fairly cool but if you have to go through town and stop at lights alot it will start getting hotter and hotter.also if you get into it a little bit it will get pretty hot.when it gets hot and you shut it off theres so much pressure in the system that water will come out the line from the overflow to the radiator where it attaches to the radiator.ive asked a couple people and they think it is my thermostat.what do you guys think ? please help i need this fixed
