Radiator overflow

That happens when the water expands as it gets warm. Does it overheat? If there are no bubbles in the water after it quits coming out, don't refill it and it won't do it again. If you have a compression leak and you're getting bubbles in the water you have a mechanical problem.
 
The radiator is not intended to be run all the way full. The level needs to be a couple inches below the cap, just enough to cover the ends of the tubes.

If it still blows coolant even with the correct level, there may be a head gasket leaking.

Other symptoms would be mystery coolant loss, exhaust steam even when warmed up, misfire, water condensation under the oil cap, on the dipstick, around the vent tube, water drops on the end of a spark plug, or blowing water out a spark plug hole after sitting overnight.
 
Agree with Steve on the tank on top of the fins is an overflow reservoir, has nothing to do with the cooliing.....carried out by th fins. When cold just cover the top of the fins. Other possibility would be too low a pressure on the cap with no stat, flow would be over the original design and could develop pressure and blow out......with too much fluid in the tank.
 
I always thought the tank should be full like in my old truck. I have a 4lb cap that came with a new radiator. Others suggest a possible head gasket leak. I will ck it. Thank y,all.
 
Back before the days of the OEM overflow tank and keep the radiator completely full to keep the air out, I too thought you were supposed to keep the
tank full. As we all know that wouldn't/couldn't happen so I had the overflow hose stuck in a gallon jug I placed between the grille and radiator and
when it got full I'd dump it back in the radiator.

I learned the right way to do it out of a tractor operator's manual many years later.
