When I'm driving down the road, it doesn't matter what speed, my temperature gauge will go deep into the red, smoke comes out from under the hood like it's a chimney and as soon as I park and turn off the car it dumps my antifreeze. This isn't just a little trickle it's like a river. It also goes through water like it's going out of style. It doesn't make any noises other than when it's overheating and making like a sizzling noise. I've asked a few people and we ruled out the thermostat, someone said something about the water pump or the head gasket but I want to know for sure. I also can't afford to take it in and have it looked at. Can somebody please help??
