Contents: Removal ⤓ Installation ⤓
Attention! To dismantle engines of all modifications, it is necessary to remove the transmission, transfer case and front propeller shaft (see subsection 9.3.6, subsection 9.1.6 and subsection 9.3.9). When dismantling the engine, apply marks of mutual orientation to the removed units and the hood, clearly mark all disconnected wires and hoses. When removing 3.0L and 3.5L engines, do not allow the temporarily disconnected air conditioner and power steering pump to hang down by the hoses. Please note that when removing the engine, you should be extremely careful, since the gaps between the engine and the body panels are small, and the unit itself has significant weight.

Removal
1. Remove the hood.
2. Remove the battery and tray.
3. Remove the cruise control intermediate rod. To do this, do the following:
- unscrew the bolt and remove the protective cover of the rod;
- disconnect the throttle cable, accelerator cable and cruise control cable from the rod. Do not unscrew the adjusting bolts and nuts, just loosen them;
- unscrew 4 bolts and remove the intermediate rod;
- remove the traction bracket, store the bolts and screws in a separate bag to screw back into place.
4. Raise the vehicle and remove the engine and transmission shields.
5. Disconnect the ground.
6. Drain the fluid from the cooling system. Drain the oil from the transmission and engine.
7. Disconnect the radiator hoses and other cooling system hoses from the engine.
8. Remove the fan shroud.
9. Remove the radiator.
10. Disconnect the exhaust pipes from the manifolds.

11. Remove the transmission (see subsection 9.3.6).
12. Remove the air filter duct.
13. Remove the power steering pump and set it aside without disconnecting it from the line.
14. Remove the generator drive belt.
15. Remove the air conditioner without disconnecting it from the line, move it to the side and secure it.
16. Remove the cooling system pump pulley with fan.
17. Disconnect all wires from the engine.
18. Unscrew the oil cooler nipple.
19. Disconnect the brake booster hose.
20. Disconnect the hose from the equalizing chamber and the heater hoses at the rear of the intake manifold.
21. Disconnect the fuel return hose.
22. Disconnect the pressure sensor wire.
23. Attach the hoist and lift the engine.
24. Remove the engine mount shields and unscrew the bolts securing the engine mounts to the frame.
25. Carefully lift the engine and remove it from the engine compartment. Place the engine on stands (not on a pallet).
Installation
The engine is installed in reverse order. First of all, install the engine, tighten the support bolts and tighten them to 44 N·m. Replace the exhaust pipe gasket on the manifold, as well as the fuel line sealing ring. Tighten the fan pulley mounting bolts to a torque of 10–12 N·m.
Tighten the radiator mounting bolts to 8–11 N·m. Fill with fluid, oil and start the engine. After warming up, restore fluid levels. Re-adjust throttle cable, belts, idle speed.
