Ok I went to an auto cross a few weeks back and now my radiator light turns on and off all the time it goes on when im cruising at slow speed sometimes and when im on the freeway sometimes it doesnt make sense cause it doesnt come on at any one time. I have a new radiator in the mail so im gonna flush the system and is if that does anything but what else might be the problem, water pump??? therostat? thanks for any input guys

 

air in the cooling system will make the light blink,or the Buzzer go off.Have you Checked the coolant level?.

 

like he said, coolant lvl is kinda obvious but important is the water temp reading hot? or at least when light comes on?

 

the coolant lvl is good that was the first thing i checked its clean also, the water temp says its good doesnt move pass the halfpoint but i hear that the stock gauges are just not telling you enough. im hoping it might be air in the system and ill get that out when i change out for my new one but thanks guys
