cooling jets and the timing chain lubrication jets.

The oil returns to the oil pan under gravity. Large drain holes through the cylinder heads and cylinder block ensure the rapid
return of the oil to the sump pan. System replenishment is through the oil filler cap on the LH cylinder head cover.
An oil evacuation tube is installed to allow oil to be drawn from the sump pan. The upper end of the oil evacuation tube is
located under the oil filler cap.
An oil drain plug is installed in the RH side of the sump pan.

Oil level monitoring is provided by an oil level and temperature sensor that measures the oil level in the sump pan. The oil
level can be displayed in the message center of the instrument cluster.



The oil level and temperature sensor supplies the ECM with a signal containing the level and temperature of the oil in the sump pan. The oil level and temperature sensor is secured to the bottom of the sump pan with three screws and sealed with a
gasket.

The oil level and temperature sensor sends an ultrasonic pulse vertically upward and measures the time taken for the pulse to
be reflected back from the top surface of the oil. This time is compared with the time taken for an ultrasonic pulse to travel a
reference distance within the oil level and temperature sensor to determine the oil level. The oil level reading is combined with
the oil temperature reading and transmitted in a PWM signal to the ECM.
