Car overheats cools when slow down?

If it overheats at speed, but cools down when you slow down, the problem is likely a head gasket. Combustion gasses are leaking into the cooling system, adding bubbles (which take the place of coolant) and extra heat. Slowing down means the engine is spinning slower, and less combustion gas gets into the cooling system.
