Ok so here's whats happening I bleed the system just like you are suppose to I've done this plenty of times and car is fine no air insystem full coolant level. After driving around for a while i get a low coolant light. So i check level to make sure its not a bad sensor and it is indeed low so I refill and bleed. Then later I start and temp is pegged even though car wasnt even running for five minutes so I turn bleeder screw that runs to radiator and about 15 seconds of air comes out. So I bleed again and fill with coolant and all air was out I swear. And then it did it again. I have burped this system so many times. Oh by the way the radiator cap is new and has been tested thermostat was also just replaced in case too. I have looked all over for leaks and cant find any so where is this engine pulling air and where is the coolant escaping. Exhaust doesnt smell like burnig coolant at all either. So I am out of ideas.

 

I would check your oil and see if it is milky. What methods are you taking to bleed your system?? Have you checked the weep hole in the waterpump to make sure it is not leaking?? You also may want to rent a pressure tester to check for leaks.

 

Yeah I was bleeding it right and nope its not a blown head gasket I think I found the leak today though its either the lower rad hose or the sensor cuz thats the side its leaking from hopefully its just a clamp or something hopefully not radiator issue I will check tomm when I have my day off
