Description of Change: There is a new expansion tank assembly for 3500 and 3500B Engines that are equipped with an expansion tank. The new expansion tank has an improved internal structure that reduces stress of the material in the walls of the tank.

The new tank can be visually distinguished from the former tank by looking at the side of the tanks. On the former tank, the coolant level gauge is mounted with a flat bar with two drilled and tapped holes. On the new tank, the coolant level gauge is mounted with two separate bosses. Refer to Illustration 1.
