C
harge Air Cooler System
Each cyl
inder bank is fitted with a charge air cooler unit wh
ich supplies pressurized air to the four cylinders via an adaptor
block. The inlet ports to the tw o charge air coolers are connected to the supercharger outlet by an inle t assembly consisting
of rubber ducts and clamp plates . An outlet stub at the rear of each charge air cooler unit provides the connection for the
by-pass valve airflow. The charge air coolers ar e water cooled via a radiator and coolant pump.
Charge Air Cooler Coolant System

Parts List
Each charge air cooler unit is a fin and tube air to liquid heat exchanger. The coolant circuit for the charge air coolers
consists of a pump, ra diator, connecting hoses and a bleed pipe.
