Have you tested it with a pressure gauge or is the coolant filling the coolant reservoir and coming out of the vent holes on top? If so, it may be merely a defective pressure cap on the pressure tank. If a foreign particle becomes lodged in the pressure or vacuum valve inside the pressure cap, the coolant system will not under normal operating pressure and it will "boil over" in the manner you describe, i.e., after a hard run and intermittently.
