COOLING - General Information
7-3
The routing and plumbing for turbocharger coolant are as shown below.
To maintain turbocharger, engine coolant is constantly kept flowing through the turbocharger-bearing housing
water jacket. Water hoses and pipes are laid to provide closed loop flow of engine coolant from the intake
manifold to the turbocharger housing to the water inlet pipe.

THERMOSTAT
The thermostat housing is located near No. 1 port in the intake manifold so that the thermostat may be
removed and inspected easily.
The thermostat is a wax pellet type. The jiggle valve is installed in the air vent located in the thermostat fla.nge.
-.I
When the engine is not running, it makes easy the bleeding of air from engine coolant. When the engine is
running (the thermostat is in closed state), the jiggle valve is closed to reduce the time required for engine
warm-up and prevent the engine from overcooling.
WATER PUMP
The water pump consists of a diecast aluminum body, stamped steel impeller, seal and grease-filled bearing
shaft. It is driven by the crankshaft pulley through the V-ribbed belt.
ELECTRIC FAN
The electrically driven cooling fan is installed to control the engine coolant temperature efficiently and reduce
loss of engine output.
