777 ( 84A ) TrucksDescription of Change: A new water temperature regulator housing cover is used to increase the heat output of the cab heater on the above models. The new cover has a check valve which lets only a small amount of coolant flow around the regulators when the regulators are closed. The former water temperature regulator housing cover had a ferrule instead of a check valve. During very cold days, this arrangement let enough water flow around the regulators to lower the efficiency of the cab heater.Adaptable As: The new 7N7690 Water Temperature Regulator Housing Cover is a direct replacement for the former 3N606 Water Temperature Regulator Housing Cover which is canceled.
