please help me on this..i have a 1995 cadi seville it has the northstar motor, i went to work tonight and when i left i had to stop somewere else and there was a big puddle under the car of water and coolant. I started it up and the message read check coolant. I did and it needed water i put some coolant in it and started on my way home and got a mile up the road and the temp read 250 so i stopped and turned off and let it sit. Got back in and tryed to get home and it was hot and i got home and shut it off. Went back out and checked it and there was coolant still in it. This has never happend to me before. I do know there is no flow comeing through the hose. Does this sound like the thermostat sticking? Or something else? Please respond asap. I need this car for work. Please let me know what i may be looking at. I am a woman and i dont want to take it in and get ripped at least what yall tell me i will kind of know what to except. thanks a bunch! Were is the thermostat located on this thing? i am just sick over this.
