Engine Cooling System
The MSX 110 and 150 engine packages feature two independent cooling circuits. The first is the FRESHWATER
circuit. The freshwater cooling circuit is responsible for cooling the intercooler, water--to--water heat exchanger,
oil storage tank, exhaust manifold / turbine housing, and exhaust system.
The second cooling circuit is the INTERNAL ENGINE circuit. The internal engine cooling circuit is responsible
for cooling the cylinder head, oil cooler, and turbocharger bearing house. Heat absorbed into the internal engine
circuit is dissipated to the freshwater circuit inside of the water--to--water heat exchanger.
