DESCRIPTION
The low temperature cooling system is a separate low pressure (5 psi) system. The function of the system is for cooling of the turbocharger bearings and charge air cooler.
OPERATION
The coolant temperature flowing into and out of the low temperature radiator is monitored through two hard-wired temperature sensors. Heat induced in the cooling system is dissipated as the coolant passes through the low temperature radiator. The cooling fan can be operated to aid in dissipating heat. When the engine is running heat will build in the turbocharger. The low temperature cooling system will operate to reduce turbocharger bearing temperature and cool the charge air cooler which reduces the temperature of the air entering the engine.
