Preparation
Engine type «WITH» can be removed from the engine compartment without the gearbox. Engine type «F», on the other hand, must be removed with the gearbox. In this case, the necessary device is a lifting block fixed in the roof of the garage, on which it is necessary to fix the transverse crossbar, on which the engine will be hung on chains. In addition, use a mobile jack and trestle jacks to lift and secure the Renault 19. When disassembling and assembling the engine, you will need an assistant. Before you start work, carefully examine the imageengine, in order to know where and how the components and elements of the engine are located in the engine compartment.
The Renault 19 engine, regardless of its type, has a large number of electrical wires and vacuum pipes. Therefore, you must first mark all connections and pipelines so as not to confuse them when assembling the engine. You can find a detailed description of the process of disassembling individual elements in the relevant chapters devoted to the consideration of these nodes.
The figure shows a balancing engine mount on which a diesel engine is elastically fixed. When removing the engine, be sure to put cross marks on all points of its attachment to the body in order to properly install the engine in place.
Elements of the right suspension
1 - engine suspension arm; 2 - oscillation limiter; 3 - fastening of the hydroelastic bearing of the engine.
Gearbox suspension elements
1 - gearbox support; 2 - gearbox; 3 - body spar.
The figure shows the spacer between the engine and gearbox. It gives the engine-gearbox linkage additional rigidity.
Depending on the type of engine, its suspension is made in different ways. It is very important to check its technical condition and tighten the bolts with the prescribed torque.
Disassembly
1. Disconnect the battery cable from the terminal and remove the battery.
2. For safety reasons, remove the hood cover.
3. Remove the air filter and air duct hoses.
4. Drain the engine oil.
5. Drain the coolant into a clean container. To do this, remove the lower hose from the radiator pipe.
6. Disconnect the interior heating hoses from the front wall of the body.
7. Remove the radiator and radiator fan.
8. On a car with a gasoline engine, disconnect the gas link from the throttle shaft lever, on a diesel engine, disconnect the gas link from the high pressure fuel pump.

Disconnect all electrical wires: coolant temperature sensor, oil pressure switch, oil level sensor, knock sensor, engine cooling fan thermostat or injection mixture temperature sensor, ignition coil (petrol engine car), glow plugs (diesel), throttle potentiometer (petrol engine car), engine stop switch and cold start device for high pressure fuel pump (diesel), starter wire, rear light switch wire and engine or gearbox ground wire.
10. Disconnect the fuel hoses: for single-point injection, the fuel supply and recirculation hoses from the injection device; for multi-point injection, from the fuel supply distributor and recirculation from the pressure regulator. On a diesel engine, remove the fuel filter with mounting and mount it vertically on the engine.

12. Type motors «F»: disconnect the ATF hose clamps (automatic transmission fluids) and a reservoir of a hydraulic drive of the steering mechanism.
13. Drain the ATF from the tank and remove the hoses from it.
14. Gas turbine supercharged diesel engine. Remove the turbocharger radiator air pipes.
15. Remove alternator V-belt.
16. Remove the power steering pump from the engine housing and tie it to the front cross member.
17. Type motors «F»: remove the connecting strut between the engine and gearbox and drain the oil from it into a clean container.
18. Disconnect lambda probe connectors.
19. Disconnect a reception pipe of the muffler and remove it.
20. Engine type «WITH»: Disconnect the coolant pump hoses.
21. Remove the V-belt.
22. Disconnect the vacuum brake booster hose from the engine.
23. Remove a metal casing of a flywheel.
24. Rotate the crankshaft V-belt pulley until the bushing key is at the top.
25. Loosen the crankshaft pulley and remove together with the bushing. In order to prevent the crankshaft from moving, engage 4th gear and have an assistant press the brake pedal or fix the engine with a screwdriver inserted into the flywheel ring gear.
26. Turn off back fastening of a starter.
27. Disconnect the sensors of the electronic ignition system.
28. Turn off connecting bolts of a transmission and the engine.
29. Unscrew the two centering pins on the left and right of the engine or gearbox.
30. Turn off the lower nut of fastening of the right (in the direction of travel) engine bearing.
31. Attach the hoist hook to the engine lug.
32. Secure the gearbox with a car jack to prevent it from falling.
33. Press the engine with a mount or a powerful screwdriver from the gearbox.
34. Start slowly and carefully lifting the engine out of the engine compartment. When doing this, be careful not to damage the right drive shaft when separating the engine from the gearbox.
35. Type motors «F»: remove the speedometer drive from the gearbox. To do this, compress the safety clips.
36. Disconnect the clutch rod from the gearbox.
37. If a transverse link is installed between the shock absorber struts, then remove it.
38. Pull back the cuff of the gearshift device and remove the control rod.
39. Tie the control rod and exhaust pipe with wire.
40. Diesel: remove the oil cooler and attach it to the engine.
41. Remove the preheat control and tie it to the engine.
42. Type motors «F»: remove the front wheels.
43. On the left side of the car, remove the brake clamp and tie it with a wire to the fender so that the brake hose is not stretched and twisted.
44. Disconnect the steering link from the steering knuckle arm.
45. Remove the drive shaft joint from the gearbox (3 bolts).
46. Disconnect the bottom fastening of a rack of the shock-absorber from a rotary fist.
47. To avoid excessive stress on the hinges, tie the drive shaft with wire to the steering. The bending angle of the hinges should not be too large. Take care not to damage the sealing collars of the drive joints.
48. Disconnect the drive shaft spacer pin from the gearbox using a punch.
49. Disconnect the lower strut mount from the steering knuckle (2 bolts with nuts).
50. Disconnect the control arm ball joint from the steering knuckle (one bolt and nut).
51. Tilt the steering knuckles outward until the drive shaft is out of the gearbox. When doing this, do not bend the drive shaft hinges too much.
52. Attach the engine to the hoist and raise it until the cables are lightly tensioned (chains).
53. Remove the engine and gearbox mount by unscrewing the fixing bolts.
54. Diesel: disconnect the engine balance mount (Right side) from the body.
55. Remove the transmission suspension.
56. Next, unscrew the bolt, remember the sequence of mounting the bracket that dampens the reactive moment, and remove it from the gearbox.
57. Carefully lift the engine with gearbox so that nothing is damaged.
Engine installation
When installing the engine, it is necessary to replace all self-locking nuts with new ones, as a poorly secured engine or gearbox mount will impair the characteristics of the vehicle and can lead to serious damage. The engine is installed in the reverse order of removal.
1. Lower the engine or the engine and transmission into the engine compartment. Be careful when doing this to avoid damage.
2. Engine type «WITH»: Align the clutch with the splines on the transmission input shaft.
3. Connect the engine, inserting the centering bolts, with the gearbox with mounting bolts and screw it on.
4. Install the engine in its original position and tighten the bolts to a torque of 45 Nm.
5. Engine type «F»: adjust the front and rear engine mounts and tighten the bolts (40 Nm)
6. Diesel: install the right balancer. Tighten the nut to a torque of 45 Nm.
7. Install the gearbox suspension and tighten the bolts to a torque of 45 Nm.
8. Install the torque damping bracket and tighten the nut on the bracket pin to 65 Nm.
9. Engine type «F»: after all fasteners have been tightened to the required torque (see table below), remove the engine and transmission from the lift hook.
10. Install other elements in the reverse order of removal.
11. Start the engine and check for oil leakage. Check the cooling system in the same way.
12. Upon achievement by the engine of working temperature check up the moment of ignition and idling. Make adjustments if necessary.
