The past week may radiator light has been coming off and on and then just stayed on. so i checked my coolant level and it was very low. i put more antifreeze into it n i took a drive and rechecked it and it was already half empty. I dont kno?? Can anyone help.

 

when you drive it the coolant level is gonna drop some until you unscrew the cap (depressurizes the loop). if you unscrew it a little you should hear air getting in and the coolant level will rise.

 

also if it was low then what you just put into the coolant resevor is going into radiator which must have been low so then it just gose into the radiator so just fill it and check it

 

------------------------If there is no obvious leak,get a pressure test.You may have a blown headgasket.Check your oil dipstick,and if the oil is milky white on the bottom of the dipstick,then antifreeze is finding it's way into your crankcase.Another method of seeing if you have a headgasket problem is to watch your exhaust pipe.If you have whitish smokeexiting,that is another warning sign.
