This is not normal and there must be a problem somewhere in the cooling system. Make sure you do not have air trapped in the system. When you fill up the over flow tank you need to run till thermostat opens and then top of. We pull a vacuum on the cooling system to make sure that we get all of the air out. Make sure that your belt is not slipping and that your fans are pulling the air the right way. Good luck, Keith
