Replace your radiator hoses, replace your thermostat (again - the high temps probably damaged it), clean your condenser (in front of your radiator), make sure your fans work properly, replace your radiator overflow tank cap. Don't drive it in the red; you probably will damage the engine. If this doesn't work, how's your coolant pump?
