Ford GT Oil Change Procedure
1. With the vehicle in NEUTRAL, position it on a hoist. Refer to section 100-02. Open the engine cover.
2. Remove the oil filter cap (6A832) from the oil filter adaptor. The used oil in the oil filter housing will automatically drain into the engine when the cap is loosened. The sealing o-ring will remain with the cap.
3. Remove the oil filter element from the housing and discard the element.
4. Install a new oil filter element and replace the cap. Ensure that the sealing o-ring is in place. Tighten the oil filter cap to 25Nm (18 lb-ft).
5. Raise the vehicle.
6. Remove the 21 bolts retaining the rear engine underbody panel (63106B08) and remove the panel. (Illustration A0094313)
7. Remove the 19 bolts retaining the front engine underbody panel (115A74) and remove the panel. (Illustration A0094314)
8. Remove the drain plug from the bottom of the oil reservoir and drain the oil reservoir. (Illustration A0089407)
9. Remove the two engine oil sump / oil pan drain plugs and drain any residual oil from the engine. (Illustration A0000058, with modification to point arrows to the drain plugs).
10. Reinstall the engine oil pan / oil sump drain plugs. Tighten the plugs to 25 Nm (18 lb-ft).
11. Reinstall the oil reservoir drain plug and tighten to 25Nm (18 lb-ft). (Illustration A0089407)
12. Lower the vehicle.
13. Refill the oil reservoir with 9.5 quarts of Motorcraft 5W-50 full synthetic oil (XO 5W-50 QGT) or equivalent meeting Ford specification WSS-M2C931-A..
14. Start the engine check for oil leaks.
15. Raise the vehicle.
16. Reinstall the front engine underbody panel and the 19 retaining bolts. Tighten the bolts to 7Nm (62 Lb-in). (Illustration A0094314)
17. Reinstall the rear engine underbody panel and the 21 retaining bolts. Tighten the bolts to 7Nm (62 Lb-in). (Illustration A0089407)
18. Lower the vehicle.
19. Check the oil sump level after running the engine. The level must be checked with 1 minute of shutting off the engine.
20. If the oil level is between the MIN-MAX marks on the dipstick, the oil level acceptable.
21. If the oil level in the sump is below the MIN mark, add oil in small amounts to raise the sump level to within the MIN-MAX range. Do not overfill the reservoir past the MAX mark on the dipstick.
Start up procedures:
1. Turn the key to the on position.
2. Hold the accelerator pedal on the floor.
3. Push in the clutch fully, then push the start button.
4. Let it crank until you see oil pressure via the gauge in the dash or for 20 seconds.
Upon seeing pressure, let up on the start button, BEFORE you let up on the pedal.
5. Release the pedal and then start normally.
--------------------------------------------------------------------------------
These start-up steps as described should be inserted as step 13.1 through 13.5.
The procedure is correctly stated:
13.1: Turn the key fully-on
13.2: Depress the go pedal to the floor and hold it
13.3: Pust start button and hold for 20 sec or until oil pressure seen on gauge
13.4: Let up on start button
13.5: Start car normally - should see oil pressure within ~1 second
Also, I like to remove the pans before doing the oil filter, AND I always shove a large towel under the filter cannister to catch any oil that may drip.
Removing the pans beforehand gives you a chance to make a quick inspection of critical components. Before removal, thump on the pans gently with your fist to see if you can produce any rattles. If so, look for the source. With the pans off, look at;
1. Any traces of fluid on the top of the pans and reference where it may come from.
2. Look at the engine oil cooler approximately underneath the filter housing. Look for any seepage.
3. Look for oil seepage at the black cover of the oil pump drive belt.
4. Look for power steering pump leakage (1 or two drops is "normal", IMO)
