Why not take it to the local nissan dealer. Let them diagnose the problem - you'll be out 100 bucks (diagnostic fee), but at least you'll get an accurate diagnosis. You can buy/replace the radiator for 100 bucks yourself.

 

or just do more of what you did before to get it better. To give you an idea I had to burp mine for about an half an hour/45 minutes to get all of the air out....while the car was running and filling the resivior as it was sucked into the radiator.

 

heres my next set of plans.....im gonna keep trying to burp it cardana, but it just sometimes overflows when im squeezing, im not getting anymore bubbles anymore, nor is the fluid level going down....so thats why i figured i was done with that...

then, njmodi, i will take it to dealer, at a dealership over here, its an 85 dollar diagnostic fee...im gonna end up doing that if all else fails....just feel like kicking myself in the *** if they find something really simple....

a dealership charged me 180 bucks plus takes when i grounded my tails out...i checked all my fuses, but when u check the power side of the fuses, even if its blown it will still give power, obviously.... i didnt realize that til it happened again...they charged me 180 bucks to change a fuse... it happened months later so they couldnt even remember to complain....i just hate mechanics with a passion..no one cares...the ones that do charge an arm and a leg for caring...but ill keep trying....

 

ECU Sensor at Auto Zone $28
Temp Sensor at Auto Zone $9

I just replaced them.

 

i thought so, but the car is actually overheating so i believe the sensors are correct, the hoses, u cant touch them, even the hose leaving the radiator is just ridiculously hot
