i was driving in the heat of the summer weather and my coolant light came up so i pulled over within 2 minutes into the nearby gas station to check out the problem. The coolant guage at that point was about 90*C. I turned it off and i noticed the hose from the radiator to the thermostat came off and there was coolant/water everywhere in the engine compartment and everything was smoking. i whiped up all the mess released the pressure, added new antifreeze, added some oil cus it lost alittle bit and then tried starting it up. It would miss and sometimes backfire it seems. I can get it started by playing with the gas alittle bit but unless i hold the gas i cannot keep it running for more than 10 sec. at idle. The motor shakes alot at idle too, but when i rev it up it smoothes out. The car just turned 200,000 too. I checked for antifreeze in the airbox and i didnt see any. But it did smoke when i removed the oil screw to add oil and it smoked out the airbox too. No smoke from the tailpipe though.
