Cooling system restrictor with hi volume pump

[Sean Marconette]

If the radiator or what is rejecting the heat does not have time to transfer the heat, more water flow will not help. Slowing the flow down will allow the radiator time to pickup and reject the heat. If the radiator is not efficient due to corrosion or the tubes contaminated not allowing heat transfer that will need addressed. Water flow is only as good as the heat rejection mediums ability to remove the heat. Overflowing the heat rejection medium will do just the opposite, the heat will be retained and the temperature will increase instead.
