No. Fill up the the radiator run it for about 5 min open cap and fill it up some more. Then run it like normal for a day or so. then pull off cap again and make sure its still full. what happens is when it runs all the hoses and everything fill up. there is no bleeder but there is an overflow clear tank. it looks like a windshield washer fluid tank. it has 2 marks on it. One when the motor is hot full and the one when the motor is cold. full.
