The cooling system removes surplus heat and holds the engine within a controlled temperature band, protecting it from the rapid damage that overheating causes. This group covers radiators and cores, water pumps, thermostats and housings, header and expansion tanks, oil coolers and aftercoolers, fans and fan drives, hoses and clamps, and coolant temperature senders. CAT generator and marine installations frequently use heat exchangers or keel cooling rather than a conventional radiator, which changes both the parts involved and the failure modes. Coolant condition matters more on these engines than on mobile plant: sustained high-load running with degraded coolant produces liner cavitation, where vibration erodes the outer liner wall until it perforates into the water jacket.

Vibration of the cylinder liner forms and collapses vapour bubbles against its outer wall, eroding the metal. Maintaining the correct supplemental coolant additive level in the coolant prevents it.
Commonly through a heat exchanger or keel cooling rather than a radiator, with seawater or raw water on the secondary circuit. Zinc anodes and heat exchanger cores are service items on these systems.
Follow the CAT interval for the coolant type in use, and test additive levels between changes. Degraded coolant loses corrosion and cavitation protection well before it looks unfit.
