How do I Replace a 2003 V6 Mustang Oil Pan

The oil pan in your 2003 V6 Ford Mustang is secured to the bottom of the engine block, and it holds a certain amount of oil for the lubrication system to do its job. If the pan in your Mustang becomes damaged and begins to leak oil, you need to install a new pan. You can replace the pan at home with the help of some special tools.

Instructions

Removing the Used Pan

1

Park your Mustang on level ground. Raise the front of the vehicle with a floor jack. Position two jack stands under the frame for support. Apply the parking brake, and block the rear wheels with chocks.

2

Place a clean, large drain pan under the engine oil pan. Remove the drain plug with a wrench. Allow the oil to drain completely. Cover the pan to keep dirt off the oil for later reuse.

3

Remove the black negative battery cable, air cleaner tube and coolant recovery reservoir with a wrench.

4

Detach the upper radiator shield with a ratchet and socket.

5

Slide the drain pan under the oil filter. Remove the oil filter with a filter wrench.

6

Set up engine lifting brackets and a support fixture on top of the engine compartment, and secure the engine.

7

Remove the left and right motor mounts with a ratchet and socket.

8

Take off the starter motor with a ratchet, short ratchet extension and socket.

9

Unfasten and lower the engine support bracket just enough to gain access to all the oil pan mounting bolts.

10

Detach the wiring harness bracket next to the oil pan. Remove the pan with a ratchet, ratchet extension and socket. Remove the oil pan from the vehicle.

Installing the New Oil Pan

11

Clean the engine block mating surface with a gasket scraper and solvent. Let it dry completely. Apply a light coat of silicone sealant to the oil pan gasket mating surface. Set a new pan gasket on the pan. Position the pan under the engine block. Install the pan mounting bolts, and tighten them with your fingers. Tighten the bolts alternately with a torque wrench, working toward the rear of the engine, to 44 inch-pounds (5 Nm) and then to 88 inch-pounds (10 Nm). Tighten the three bolts that hold the transmission housing bell to 33 foot-pounds (45 Nm). Make sure the pan drain plug is correctly installed.

12

Reinstall the wiring harness to the oil pan and the engine support bracket. Tighten the larger upper bolts to 85 foot-pounds (115 Nm) and the smaller ones to 68 foot-pounds (90 Nm) with the torque wrench.

13

Replace the starter motor, and tighten the bolts to 18 foot-pounds (15 Nm) with the torque wrench.

14

Install the left and right motor mounts, and tighten the bolts to 85 foot-pounds (115 Nm) with the torque wrench.

15

Replace the oil filter by hand. Replace the upper radiator shield with the ratchet and socket.

16

Lower your Mustang with the floor jack.

17

Connect the black negative battery cable, air cleaner tube and coolant recovery reservoir with the wrench.

18

Refill the engine with oil using a small funnel.

19

Check the oil pan for leaks.
