COOLING AND LUBRICATING SYSTEMS

LEARNING OBJECTIVE: Explain the relationship of the cooling system to engine operation. Identify design and functional features of individual cooling system components. Identify maintenance procedures applicable to cooling systems. Identify types of lubrication systems and explain their operational charactetistics and maintenance requirements.

All internal combustion engines are equipped with cooling and lubricating systems that work in conjunction with each other to promote efficient engine operation and performance. The cooling and lubricating systems discussed in this chapter, along with their respective components and maintenance requirements, are representative of the types of systems you will be expected to maintain.

Because of the variety of engines used, there are differences in the applications of features of their cooling and lubricating systems. Keep in mind that maintenance procedures and operational characteristics vary from engine to engine; therefore, always refer to the manufacturer’s service manuals for specific information
