Oil Line: Description and Operation

OIL COOLER & LINES

DESCRIPTION





Depending on vehicle options, some models use 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. 102).

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 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. 102).
