Ok, two weeks ago, I did the cooling overhaul, water-pump, thermostat, expansion tank, upper and lower radiator hoses. Hose popped off the expansion tank so I filled it with water after I got the hose back on, and went on my way. Different hose popped off again a few nights ago, so I put it back on and filled it with water, and this is when everything awful starts happening. After filling the car with water, I got back on the highway to the car overheating. Cut the car off and pulled off immediately. Had to stop three more times on the way home to let it cool off before trying again. This morning I picked up coolant and distilled water and tried to flush the cooling system. The bolt on the block was impossible to get off, so I left it but was able to flush everything else. The whole time the key was in the on position and the heater was on low and 91 degrees. After the flush, I started the car and ran it until it came to temp and dropped it off the jack stands... Took it for a ride around the block and the temperature climbed again. On the OBC it started on 101 and got to 115 before coasting back into the driveway. I don't know why its dong this, should I flush the coolant again or could it be another problem? Now the whole time, once the car REACHES temp, hot air blows out, but until then, nothing really comes out. Also, when draining the coolant today, there was no oil so I hope its not a head gasket.
