AIR INLET AND EXHAUST SYSTEM
The aftercooler is located at the center of the
vee, and has a coolant charged core assembly. The
3516 can have two core assemblies. Coolant from water
pump (3) flows through pipe (2) into the aftercooler. It
then flows through the core assembly (assemblies) and
back out of the aftercooler through a different pipe into
the rear of the cylinder block.
There is a connector (tube) that connects the
bottom rear of each core assembly to the cylinder block.
This is used to drain the core assembly (assemblies)
when the coolant is drained from the engine.
Inlet air from the compressor side of the turbo-
chargers flows into the aftercooler through pipes. This
air then passes through the fins of the core assembly
(assemblies) which lowers the temperature. The cooler
air goes out the bottom of the after-cooler into the air
chamber, and then up through the elbows to the inlet
