F8QT engine: 1 – bolt, 60 Nm; 2 – Power steering pump pulley; 3 – bolt, 10 Nm; 4 – bolt (cars without air conditioning), 25 Nm; 5 – bolt, 60 Nm; 6 – Power steering pump; 7 – bolt, 60 Nm; 8 – air conditioning compressor; 9 – bolt, 12 Nm; 10 – connection of engine oil radiator hoses (cars with air conditioning); 11 – bolts (cars with air conditioning), 10 Nm (flange bolt), 6 Nm (bolt with washer); 12 – bolt, 50 Nm; 13 – Engine support bracket; 14 – bolt, 90 Nm; 15 – connection of engine cooling system hoses; 16 – connection of heater hoses; 17 – coolant temperature sensor connector (to the temperature gauge); 18 – coolant temperature sensor connector; 19 – engine assembly
17. Unscrew the bolts and remove the hoses 10 (Fig. 4.32) of the engine oil radiator (cars with air conditioning).
18. Unscrew bolt 4 (cars without air conditioning).
19. Loosen the bolts and remove pulley 2 of the power steering pump.
20. Loosen the bolts and remove the power steering pump from the bracket together with the hoses connected to it.
Caution: Tie the removed power steering pump with wire and place it in a place where it will not interfere with the removal and installation of the engine assembly.
21. Disconnect the air conditioning compressor wire connector and remove compressor 8 from the bracket together with the connected hoses.
Caution! Tie the removed compressor with wire and place it in a place where it will not interfere with the removal and installation of the engine.
22. Disconnect the connectors of the coolant temperature sensor (on the temperature gauge) 17 and the coolant temperature sensor 18.
23. Loosen the clamps and remove the heater hoses 16.
24. Loosen the clamps and remove the engine cooling system hoses 15.
25. Unscrew bolts 11 (cars with air conditioning).
26. Place a hydraulic jack under the engine.
27. Remove the special tool used to remove the gearbox from the engine.
28. Secure the engine to the crossbar and hang it on a hoist or similar device.
29. Insert a wooden block between the jack support foot and the engine oil pan and lift the engine slightly to relieve the support, then remove the engine support bracket.
30. Check that all wires (electrical connectors), hoses, etc. are disconnected from the engine, and then slowly lift the engine out of the engine compartment.
Installation
Installation is carried out in the reverse order of removal, taking into account the following.
1. When installing the motor, carefully check that the wires, hoses and wire connectors are not pinched.
2. Place a hydraulic trolley jack under the engine (inserting a wooden block between the jack support foot and the engine oil pan) and install the engine support bracket, adjusting the engine position using the jack.
3. Support the engine with a jack and disconnect the hoist.
