if it's spurting with force, that's abnormal. if it just dribbles out then it's overfilled.

radiator filling can be maddening and a good way to blow head gaskets.


fill the radiator to about 1/4" above the tubes, just cover them, don't submerge them completely. close cap. warm up car, put 1/2 of the amount the overflow holds and let the car warm up a little, the overflow will blow a few little bubbles. let the engine cool down, it will suck in coolant. if the overflow gets low add a little to keep some liquid in the bottle.
