I just bought a 06 chevy equinox. I flushed my system due to finding out previous owner had stop a leak in actual coolant tank. I have water instead of coolant currently because i kept running through it. Now i seem to hold the water, but my car keeps overheating. After the flush, my heater stopped working. Blows cold air now. As soon as i start my car, it doesnt take long for the temp gauge to go up. Then itll eventually overheat or try to within not even 30 minutes of driving it. I replaced my thermostat. My fans work. Theres no smoke coming out of exhaust. Theres no coolant mixed with my oil. Nothing of the sort. Only thing that happens when it overheats is just bubbling in the coolant tank. I dont care what it is. But i do pray it is NOT the head gasket. :
