Oil Cooler: Description and Operation

OIL COOLER & LINES
DESCRIPTION





The 2.7L engine (Sales Code EES only) uses an engine oil cooler that is mounted inside the right radiator tank (Fig. 90). 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. 91).
