ENGINE OIL COOLER—2.7L
DESCRIPTION
The 2.7L engine (Sales Code EES only) uses an
engine oil cooler that is mounted inside the right
radiator tank (Fig. 15). Oil lines connect the cooler to
the engine.
OPERATION
Engine oil travels from the engine through the
supply line and into the cooler. The supply line is
connected to a control valve that allows engine oil
flow when pressure is above 138–207 kPa (20–30 psi)
and an internal orifice limits 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. 16).
