Engine removal and installation — general description (Renault Espace I)

1. This chapter describes the process of removing and installing the engine without the gearbox, taking into account the differences between models and the engines installed on them.

Petrol engines - model J11

2. Disconnect the battery cables. If your vehicle has a radio with a security code, you will need to have the code handy when disconnecting the battery so that the radio can be reset to working mode.

3. Drain the coolant. The drain hole is on the side of the cylinder block. The radiator can be emptied of coolant by disconnecting the lower hose. The coolant can be drained into a reservoir for further use, provided that it has been changed recently.



4. Remove the hood. Mark the hinge outlines with a pencil. This will allow the hood to be reinstalled without any adjustments.

5. Remove the top frame cross member.

6. Remove the radiator with the left shield.

7. Remove the radiator grille, front end and lower frame cross member.

8. If the vehicle has power steering, remove both screws (1) (see illustration). Remove the drive belt. Move the pump with hoses to the side and hang it up.

9. Disconnect the intake manifold with the air intake sleeve from the carburetor. The latter is attached with a plate to the cylinder head cover.

10. Remove the air filter. On a carburetor engine, close the carburetor opening properly.

11. Disconnect all electrical wiring and fuel lines. Mark the cables in a way that is convenient for you. Make sure that there is no fuel left in the hoses. For carburetor engines, disconnect the hoses from the fuel pump. Also disconnect the vacuum hose from the brake booster.

12. Disconnect the exhaust pipe from the manifold (see illustration). A wrench with an extended socket head is better suited for this purpose.

13. Jack up the gearbox (place a wooden block between the jack head and the gearbox).

14. Unscrew the bolts connecting the engine and gearbox, then remove the starter and disconnect the shield from the flywheel housing. The ignition timing sensor is mounted in one of the gearbox bolts. The bolts used must be marked so as not to mix them up during assembly. The sensor must be positioned so as not to damage it.

15. Hook the engine to the mounting eyes and suspend it with a winch. Use cables or chains for this purpose. The bracket shown in the illustration gives the engine an additional support point and ensures its balance (see illustration).



16. Make sure the transmission is securely supported by a jack and the engine is securely suspended by cables or chains. Using a socket wrench, remove the nuts on the back of the engine (see illustration). To do this, slightly lift the engine until its mounting brackets are accessible.

Petrol engines - model J63

Note: Removal of the late model Espace 4-cylinder engine is similar to that described for the early model engine. However, you should pay attention to the following points.

17. Disconnect the injection system wire connection plugs located under the right headlight.

18. Disconnect in the following order: hood, front shield, upper frame cross member, front end, radiator with cooling fans, air filter, heater blower with heat shield.

19. In addition to the electrical wiring and heater hoses, disconnect the fuel lines from the fuel distributor pipe, the power steering pump hoses and the clutch pedal drive cable.

Turbocharged diesel models

Note: The turbocharged diesel engine is removed in the same way as the 4-cylinder engine without a gearbox.

20. Disconnect the battery cables. If your vehicle has a radio with a security code, you will need to have the code handy when disconnecting the battery so that the radio can be reset to working mode.

21. Disconnect the diesel fuel heater cable (see illustration).

22. Drain the coolant from the cooling system. If the coolant has recently been changed, drain it into a canister and use it again later.

23. Remove in the following order: hood, front shield, upper frame cross member, front end, radiator with cooling fans, air duct (air filter, compressor, charge air cooler, intake manifold), embedded connections (oil may leak out) disconnect the pipe leading to the turbine from the intake manifold.



24. Disconnect the clutch pedal cable and the accelerator pedal cable.

25. Disconnect all electrical wires connecting the engine to the body.

26. Remove the engine mounting stops installed on diesel engines. They are located on the frame crossmember.

27. Disconnect the drain pipe from the turbocharger.

28. Disconnect the following components: fuel supply and return hoses (the hoses must be pinched to prevent fuel leakage), hose from the brake booster vacuum pump, hoses of the power steering gear (one hose is secured with a clamp, the second - with a threaded connecting element (see illustration)), the supply pipe from the intake manifold.

29. Jack up the gearbox until you feel noticeable tension (place a wooden block between the jack head and the gearbox).

30. Remove the bolts connecting the engine and gearbox, the starter, and the shield from the flywheel housing.

31. Hook the engine to the mounting eyes and suspend it with a winch. Use cables or chains for this purpose. The bracket shown in Illustration 1.15 provides the engine with an additional support point and ensures its balance.

32. Make sure the transmission is securely supported by a jack and the engine is securely suspended by cables or chains. Using a socket wrench, loosen the nuts on the underside of the engine (see illustration). To do this, lift the engine slightly until the engine mounting brackets are accessible.

V-shaped 6-cylinder engine (V6)

Note: The V6 engine is removed in the same way as described above without the gearbox.

33. Depending on the weight of the engine, it is necessary to select a bracket suitable for lifting the engine. Before removing the engine, take a look at the mounting bracket shown in Illustration 1.49 to determine whether you will use such a device to lift the engine or whether you can use only cables or chains. Removing the engine should not be carried out if there is a risk that parts and mechanisms in the engine compartment may be damaged or there is a risk of injury.

34. Disconnect the negative cable from the battery terminal (don't forget about the safety code if the car has a corresponding radio receiver).

35. Drain the coolant. To do this, place a container of suitable capacity under the car. The lower radiator hose can be blocked. Some coolant will remain in the cylinder block, it also needs to be drained. To do this, remove the two plugs from the drain holes. One of them is located above the oil filter (see illustration), the second one is on the opposite side near the plug socket (the plug connector must also be disconnected). The drain plugs have a square socket head screw, so you must use the appropriate wrench.

36. Remove the hood, front shield, upper frame crossmember, front end, radiator with fans, air filter, heat shield of the heater fan, headlights and generator. Wire connectors must be marked before disconnecting them.

37. Remove the fuel pump mounting bracket and place it on the engine. This part is located next to the coolant system corrugated container under the small connecting hose.

38. Disconnect the high pressure hose from the power steering pump and the low pressure hose from the replenishment tank.

39. Disconnect all remaining cooling system hoses from the engine.

40. Disconnect the fuel supply hoses from the fuel supply pipe.

41. Disconnect the throttle control lever cable.

42. Disconnect the Lambda sensor connector, as well as the ignition timing sensor connector located near the flywheel housing.

43. Jack up the front of the car and securely support it on stands.

44. Remove the bulkhead under the flywheel housing and remove the shield from the right side of the housing.

45. Remove the mounting nuts and disconnect the outlet pipe from the manifold. Remove the springs and spacers and disconnect the tubes (see illustration).

46. Place a lift under the gearbox and lift it until you feel resistance. Try not to damage the gearbox. Now remove the bolts connecting the engine and gearbox.

47. Disconnect the cable and remove the starter.

48. Disconnect the left engine bracket (see illustration) and remove it together with the cushion. On the right bracket, detach the cushion from the bottom.

49. Lift the engine using a winch, having previously hooked it to the mounting eyes. Use chains or cables to lift the engine. A mounting bracket can be used to lift the engine (see illustration). The hooks are inserted into the mounting eyes.

50. From the bottom of the vehicle, unscrew the engine mounting nuts on the right and left of the oil pan.

51. Lower the vehicle onto its wheels and check again that all connections are disconnected.

52. Make sure that the jack is securely fastened under the gearbox and begin to carefully lift the engine. When removing the engine, try not to damage the other mechanisms and units located in the engine compartment. Do not let the engine hang on the input shaft of the gearbox. As soon as the engine hits something, it is necessary to determine the cause. Perhaps there is still an inseparable connection somewhere.

Engine installation

53. Perform installation in reverse order, following the following instructions:

54. All engines have two locating bushings that are inserted into the cylinder block, one on each side, they ensure perfect alignment of the engine and gearbox. Sometimes when the engine is removed, these bushings remain in the gearbox. If this happens, pull them out with pliers and reinsert them into the cylinder block. Replace any deformed or damaged locating bushings.

55. Lubricate the gear engagements of the gearbox input shaft with graphite grease.

56. On a four-cylinder engine, the rear starter stop is attached only after the engine has been installed. Otherwise, it will be very difficult to install the starter.

57. Check the engine oil level or add oil.

58. Fill with coolant. The cooling system must be purged before this.

59. If necessary, fill and bleed the power steering system.

60. Connect the accelerator pedal and clutch pedal drive cables.
