How to Change a 2004 Sebring Oil Sending Unit

The 2004 Chrysler Sebring base model sedan came with a 2.4-liter four-cylinder engine and a four-speed automatic transmission. The dashboard on your Sebring doesnt have an oil gauge, but it does have a low oil pressure warning light. The light will illuminate anytime oil pressure is insufficient, which is normally caused by a low oil level or a faulty oil pump. If your oil pressure tests correctly, the switch is at fault and needs to be replaced to shut off the light. The pressure sensor is located on the front side of the engine block closest to the crank pulley and has a single wire connected to it.

Instructions

Removal

1

Park the vehicle on a level surface and set the parking brake. Lift the front of the vehicle into the air with a floor jack and place jack stands under the front sub-frame. Lower the vehicle until it rests securely on the jack stands. Allow the engine to cool completely before continuing.

2

Remove the driver side splash shield from under the vehicle, if equipped, using a socket and a ratchet. Position yourself under the vehicle to that you can view the front side of the block.

3

Examine midway up the engine block, along the driver's side, to locate the oil pressure switch. Remove the bolts securing the heat shield to the engine block with a socket and ratchet. Squeeze the locking tab and pull the single wire connector out of oil pressure switch.

4

Place the oil pressure switch wrench over the switch. Install the ratchet to the special tool and rotate the switch counterclockwise to remove it from the block. Remove the oil pressure switch from under the vehicle.

Installation

5

Apply thread sealer tape to the threads of the new oil sensor switch, if it has not been applied by the manufacturer. Thread the oil pressure switch into position on the engine block until hand tight.

6

Install the oil pressure switch wrench over the new switch. Attach the torque wrench to the special tool and tighten the new pressure switch to between 12 and 16 foot-pounds with a torque wrench. Plug in the single wire connector.

7

Hold the head shield over the pressure switch and install the mounting bolts; tighten them snug with a socket and ratchet. Lift the driver side splash shield into position and install the mounting bolts, if equipped.

8

Lift the front of the vehicle off of the jack stands and remove the jack stands. Lower the vehicle to the ground. Start the engine to verify the oil pressure light is no longer illuminated.
