I recently had a shop replace my big radiator hoses and do a coolant flush and replace with red coolant. Yesterday i went outside and checked my car and there was coolant on the ground after sitting for a day. I turned the car on with the rad cap off (which is also brand new) and it kept overflowing out of the radiator cap, then sort of burping itself out and redoing it. The three photos are within about 5 seconds. There’s also nothing going through the coolant overflow pipe. I have no real idea about anything on cars so any help would be good thanks.
