When I put coolent in the overflow bottle it runs out the overflow spout on the side of the bottle but the bottle is still empty?

BEST ANSWER: I had the same problem, builds to much pressure in the radiator, I replaced the cap and the thermostat with lower pressure rating, problem solved, for me anyway, I replaced the overflow bottle because mine was cracked.
