Antifreeze keeps draining from radiator to overflow jug. Does not go back into radiator, I have to add antifreeze every time I ride. Could it be that the radiator cap is loose? I dont know, Please Help! It only overheated once, it wasnt bad at all, but when I take it for short rides, the antifreeze squirts out of the overflow bottle.
What do you mean you don't know if you have a loose radiator cap? Why don't you just check it?
I'm afraid that's not your problem though. You have a blown head gasket if its pushing out the reservoir cap.
If the coolant does return to the radiator as it cools down, perhaps it has a defective or wrong radiator cap - otherwise it probably has a leaking head gasket :dito:
