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 detachable wires and hoses. When removing engines with a volume of 3.0 liters and 3.5 liters, do not allow the temporarily disconnected air conditioner and power steering pump to sag on the hoses. Please note that when removing the engine, you should be extremely careful, since the gaps between the engine and body panels are small, and the unit itself has a significant weight.

Removing
1. Remove the hood.
2. Raise the vehicle and remove the engine guards.
3. Decompress. To do this, disconnect the connector at the rear of the fuel tank, start the engine and, after stopping it, turn off the ignition.
4. Disconnect the ground.
5. Drain the liquid from the cooling system. Drain the oil from the transmission and engine.
6. Disconnect the engine radiator hoses and other cooling system hoses.
7. Remove the radiator.
8. Remove the fan shroud.
9. Disconnect from a collector an exhaust pipe.
10. Remove the transmission (see subsection 9.3.6).
11. Remove the air filter duct.
12. Disconnect the throttle cable.
13. Disconnect wires from the conditioner.
14. Remove the air conditioner without disconnecting it from the line, take it aside and fix it.
15. Remove the power steering pump and set aside without disconnecting from the line.
16. Disconnect the cruise control hose (if provided).
17. Disconnect fuel hoses (starting with the high pressure hose, which is covered with a rag before disconnecting), disconnect the fuel system vacuum hose.
18. Remove the throttle sensor, ignition coil, power transistor block, recirculation temperature sensor, all fluid temperature sensors, oil pressure sensor, alternator, and thermal switches.
19. Remove wires of connection of the engine with weight.
20. Disconnect the exhaust vacuum hose and brake booster hose.
21. Disconnect the connector from the air idle corrector motor.
22. Disconnect the remaining wires.
23. Attach the hoist hoist and hang 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 pallet).
Installation
Engine installation is carried out in the reverse order. First of all, install the engine, wrap the support bolts and tighten them with a torque of 30–40 Nm. Replace the exhaust pipe gasket on the manifold and the mounting bolts, as well as the O-ring of the fuel line. Tighten the radiator mounting bolts with a torque of 8–11 Nm.
Fill with liquid, oil and start the engine. After warming up, restore fluid levels. Re-adjust cable, belts, idle and ignition.
