ENGINE OIL COOLER—3.2/3.5L7
DESCRIPTION
The 3.2/3.5L engine uses an engine oil cooler that
is mounted inside the right radiator tank. An oil
cooler pressure control valve is used to control flow to
the cooler (Fig. 17).
OPERATION
Engine oil travels from the control valve through
the supply line and into the cooler. The control valve
allows engine oil flow when pressure is above
138–207 kPa (20–30 psi) and an internal orifice lim-
its oil flow to a maximum of 11.3 LPM (3 GPM). The
engine oil exits the cooler through the oil return line
and is returned to the engine oil pan (Fig. 17).
