Cooling Water System
The cooling water system consists of a low temperature system and a high temperature system.
The water in the low temperature system is passed through the charge air cooler and the lubricating oil cooler, and the alternator if the latter is water cooled. The low temperature system is normally cooled by fresh water.
L23/30H
The high temperature cooling water system cools the engine cylinders and the cylinder head. The high temperature system is always cooled by fresh water.
Tools
The engine can be delivered with all necessary tools for overhaul, for each specific plant, most of the tools can be arranged on steel plate panels.
