i change the radiator antifreeze today and i have the add coolan light on now but the radiator is full the bottle is full and i did it right. what could be? thanks

 

you got some air in there, and when its running its proabally seeing it low, what I always do is fill it up as much as I can then leave the cap off and start it up, and wait for the thermostat to open, and then pour you 50/50 in there as need be usually always works...

 

i did that ,i even dump the new coolan and put more, probably i did something wrong

 

Those coolant sensor level things on top of the radiator are very sensitive. It could be just barely low and still say add coolant.. Make sure you plug the little connector in really good, also check the other connectors around the radiator

 

I had to re-sodder my collant sensor wire a few times...

 

well didnt came on today. maibe is fixed. anyway thanks
