Engine Specifications
Note: The front end of the engine is opposite the flywheel end of the engine. The left side and the right side of the engine are determined from the flywheel end. The number 1 cylinder is the front cylinder.C32 Marine Engines

Rotation (flywheel end) Counterclockwise Electronic Engine Features
The engine has built-in diagnostics in order to ensure that all of the components are operating properly. In the event of a system component failure, the operator will be alerted to the condition via the diagnostic lamp that is located on the control panel. Cat Electronic Technician (ET) can be used to read the numerical code of the faulty component or condition. Intermittent faults are also logged and stored in memory.These Cat Marine Engines are designed with electronic controls. The integral on board computer controls the operation of the engine. Current operating conditions are monitored. The Electronic Control Module (ECM) controls the response of the engine to these conditions and to the demands of the operator. These conditions and operator demands determine the precise control of fuel injection by the ECM. The electronic engine control system provides the following features:
Engine monitoring
Electronic engine speed governing
Automatic air/fuel ratio control
Torque rise shaping
Injection timing control
System diagnosticsThe engine ECM will automatically provide the correct amount of fuel in order to start the engine. Do not hold the throttle down while the engine is cranking. If the engine fails to start in 20 seconds, release the starting switch. Allow the starting motor to cool for 2 minutes before using the starting motor again.For more information on electronic engine features, refer to the Operation and Maintenance Manual, "Features and Controls" topic (Operation Section).Engine Cooling and Lubrication
The engines have water-cooled exhaust manifolds, risers, and turbochargers. These components will minimize the heat that is radiated into the engine room. Changes to the cooling system of these engines minimize the weight and the size of the engine. These changes also improve the engine performance. The cooling system heat exchanger, the expansion tank, and the deaerator help to prevent cavitation of the water pump. This helps to maintain the performance of the jacket water pump.The cooling system consists of the following components:
Centrifugal jacket water pump that is driven by gears
Two water temperature regulators which regulate the engine coolant temperature
Oil cooler
Auxiliary water pump or an SCAC water pump
Deaerators that remove air from the coolant
Raw/sea water aftercoolingThe engine lubricating oil, which is supplied by a gear-type pump, is cooled. The engine lubricating oil is also filtered. Bypass valves provide unrestricted flow of lubrication oil to the engine components during the following conditions:
High oil viscosity
Plugged oil cooler or plugged oil filter elements (paper cartridge)Marine Transmissions
Several manufacturers of marine gears offer marine transmissions through local distributors. Lubrication oil for the marine transmission can be cooled by an optional engine mounted transmission oil cooler (certain engine ratings).Engine Service Life
Engine efficiency and maximum utilization of engine performance depend on the adherence to proper application guidelines and operation and maintenance recommendations. In addition, use recommended fuels, coolants, and lubricants. Use this Operation and Maintenance Manual as a guide for required engine maintenance.Expected engine life is generally predicted by the average power that is demanded. The average power that is demanded is based on fuel consumption of the engine over time. Reduced hours of operation at full throttle and/or operating at reduced throttle settings result in a lower average power demand. Reduced hours of operation will increase the length of operating time before an engine overhaul is required. For more information, refer to the Operation and Maintenance Manual, "Overhaul Considerations" topic (Maintenance Section).
