I was driving home when i started to hear a weird noise coming from the engine on the drivers side of my jeep. I was worried but i was almost home so i drove slow. I noticed that when i stopped giving it gas the noise stopped. when i got home the check gauges light came on so i popped the hood.....turns out i was out of antifreeze. i guess thats why my heater was pumping out only cold air. I could also smell a wierd burning smell. So i topped it off and let the jeep run for a couple of minutes and when i turned it off, i tried to turn it back on to see if it started fine and the vehicle wont turnover. any ideas would be much appreciated. I hope the engine didnt seize on me.
