TURBOCHARGER COOLANT ROUTING
Engines equipped with a Turbocharger maintain a
continuous engine coolant flow through the Turbo-
charger bearing housing water jacket. Hose and tube
assemblies provide a closed loop coolant flow from
the cylinder block water jacket to the turbocharger
housing and back to the cylinder head waterbox (Fig.
2).
Excluding heated intake manifold hose routing
(hose is routed from waterbox directly to heater), all
other system functions are essentially the same as
shown for standard engines.
During any reassembly procedures all pipe fittings
in water jacket, bearing housing and waterbox re-
quire cleaning and application of thread sealant for
entire length of threads. Tighten all fittings to
torque specified in (Fig 2).
WATER PIPES—3.0L
The 3.0L engines use metal piping beyond the
lower radiator hose to route coolant to the suction
side of water pump, located in the V of the cylinder
banks.
These pipes are also provided with inlet nipples for
thermostat bypass and heater return coolant hos-
es,and brackets for rigid engine attachment. The
pipes employ O-rings for sealing at their interconnec-
tion and to the water pump (Fig. 4).
