Overview
OVERVIEW
The pressurized cooling system allows coolant to circulate around the engine
and the heater circuit while the thermostat
main valve is closed. The primary function of the cooling system is to maintain
the engine within an optimum temperature
range under changing ambient and engine operating conditions. Secondary
functions are to provide automatic transmission
fluid cooling, turbocharger cooling and interior cabin heating.
When the engine is running the coolant is circulated around the engine cooling
system by the coolant pump. From the
coolant pump, coolant flows through the cylinder block and the cylinder heads.
Some of the coolant leaving the engine is
directed through the turbocharger before returning to the water outlet.
The main engine thermostat is located at the engine inlet up-stream of the water
pump. During initial engine warm up the
thermostat main valve is closed: preventing coolant flow through the radiator
and transmission cooler. When the
thermostat main valve is closed, coolant is circulated through the bypass
circuit, cabin heater, engine oil cooler and degas
tank to allow these systems to function during warm up.
Once the coolant temperature exceeds the thermostat start to open temperature of
82-90
