Okay here's the deal. I have replaced the thermostat, water pump flushed and filled the system again... I still can not get the engine to stop running hot then cold then hot again. Tonight I drove the car for a solid 30 mins and the heat inside was intermittent and the temp guage was bouncing between 1/4 and 3/4 looking at the guage. So after dealing with the same type of situation for over a week i got pissed and opened the bleeder just after the thermostat all the way open and got nothing but hot air, not even steam. Pulled the upper rad hose off and it was wet like coolant had been flowing through but was just pressurized with air. I did this literally the moment i got out of the car, foolish yes i know! I am also still noticing that when i rev up the motor the rad hoses collapse completely flat. I have put nearly 3 gals of 50/50 into the system and have no visible leaks (oil looks fine). At this point i just want to figure out why the coolant isnt flowing properly so i can get heat inside the car
