3-160. EXHAUST MANIFOLD - MAINTENANCE INSTRUCTIONS.
The one-piece, water cooled exhaust manifold is cast with an integral water jacket surrounding the
exhaust chamber. The diameter of the exhaust chamber increases uniformly from one end to the other where it
terminates in a flange to which an elbow and flexible exhaust connection is attached. A portion of the engine
coolant is by-passed from the water manifold into the rear end of the jacket surrounding the exhaust manifold
and is discharged from the forward end through a tube into the lower section of the expansion tank. A draincock
is installed in the bottom of the manifold for draining the water jacket. A plug is provided in the bottom of the
exhaust outlet elbow for draining moisture condensed from the exhaust gases.
