Low Engine Coolant...

[MatthewDavid]

So some y'all will remember me Posting about a low engine coolant error comming up... well I did some research the sensor seams fine... I cleaned it and it's free to move up and down... the question now is... I was watching it... and when the car's up to temp it sucks all the coolant out of the tank throwing the error... but when it's cold it's full... also if you try adding anything while it's warm it just fills back up then when you seal it... it goes back down... is it just messing with me?... thinkin it's having fun?... how do you fix that?

Have you tried filling at the crossover? That little metal tube in front of the radiator. Thats the highest point on the system and goes directly into the engine and radiator then the extra tank. I think a 1/4 inch socket will fit.
