Removal
Note: This operation will require a hoist and winch. A new gasket will be required for installation and new exhaust clamp nuts may be required.
1. Disconnect the negative battery terminal.
2. Remove the air cleaner as described in Chapter 4.
3. Unclip the radiator fan shroud and position it on top of the fan blades as described in Chapter 3.
4. Remove the engine shield from below as described in Chapter 11.
5. Remove the front stabilizer bar as described in Chapter 10. Please note that the stabilizer can be left under the car, providing the ability to unscrew the support mounting bolts.
6. Drain the engine oil as described in Chapter 1A.
7. Where provided, disconnect the wires from the oil level sensor mounted on the pan.
8. Disconnect the wires from the oil pressure warning light switch.
9. On automatic transmission models, remove the mounting bolts and disconnect the transmission fluid heat exchanger lines from the pan.
10. Similarly, on models with a level control system, unscrew the mounting bolt and disconnect the hydraulic tube from the pan.
11. Disconnect the front sections of the exhaust system from the exhaust manifold, as described in chapter 4.
12. Where provided, working from underneath the vehicle, loosen the clamp nuts and release the exhaust system components from the bracket on the gearbox.
13. Insert a metal or thick cardboard sheet between the rear of the engine and the engine compartment bulkhead to protect the bulkhead and brake pipes during the following operations (see fig. 11.13).

14. Disconnect the steering trailing rod on the left side and the steering damper on the right side, as described in Chapter 10.
15. Connect the hoist and winch to the engine rigging brackets and lift the hoist to support the engine.
16. Working in turn on each side of the vehicle, remove the bolts of the lower right and left engine mounts.
17. Carefully lift the engine, enough to unscrew the oil pan mounting bolts.
18. Working gradually in a diagonal sequence, unscrew the pan mounting bolts (see fig. 11.18). Remember the location of the bolts as they vary in length.
