Removal and installation of the power block (4-cylinder)

            0

Warning: Gasoline is highly flammable. Use extreme caution when working on the fuel system. Work in a well ventilated area - open all windows and doors to create an exhaust hood. Do not smoke or allow naked flames or incandescent lamps without protective covers near the work area. Please note that the fuel used in household appliances (heaters, boilers, dehumidifiers), also poses a risk. Keep this in mind when working near such equipment. Near the working area, it is always necessary to have a fire extinguisher suitable for extinguishing burning oil products, and before starting work, you must read the instructions for its use. If fuel comes in contact with skin, wash immediately with soap and water. Please note that fuel vapors are just as dangerous as liquid fuels.


Note: Please read this entire paragraph as well as the previous paragraph before performing this procedure. The engine and transmission must be removed as a unit, lowering it to the ground and removing it from under the car, and then the engine and transmission must be separated.

14. Turn out bolts of both parts of a heat-insulating casing of a final collector. Detach the coolant hose to remove the top cover.


15. Remove the accessory drive belt (Chapter 1).

16. Turn out bolts of the pump of a hydrosystem of a steering (chapter 10). Fix it as far as possible from the power block without disconnecting the hoses.

17. Raise the car and place it on supports. Then remove the front wheels. Drain the cooling system and (if you disassemble the engine) drain the engine oil and remove the oil filter (Chapter 1). Drain the transmission fluid as well (chapter 7).

18. Pull out the bottom part of the heat-insulating casing of a final collector.

19. Turn away nuts for a detachment of a reception pipe of an exhaust system from a collector. Then get the whole system out of its rubber mounts and pull it out from under the car (chapter 4A).

20. On manual transmission models, mark the position of the shift lever and transmission support rods on the rear of the transmission. Loosen the fixing nuts and remove the linkage heat shield from the bottom. Unbolt the rear end of the linkage to the bottom, slide the linkage back and tie it to the bottom (chapter 7A).

21. Disconnect both connecting links of the stabilizer of transverse vibrations from the corresponding suspension struts, and the ends of the transverse steering rods from the steering knuckles. Notice the brake hose bracket attached to each link stud. Loosen the clamp bolt securing the ball joint of each lower front suspension arm to the steering knuckle (chapter 10). Make sure both ball joints can be released from the steering knuckles if required and leave them in place with clamp bolts if necessary.

22. On models with an air conditioning system, remove the accumulator/drier bolts from the subframe. Fix this assembly as far as possible from the power block without disconnecting the system hoses.

Warning: Do not disconnect refrigerant hoses.


23. Turn out bolts of the steering mechanism from a stretcher. If the bolts are not accessible from above, then you will need a Ford tool to get to them from under the car (chapter 10).

24. Turn out two bolts of fastening of the pipeline of a hydraulic system of a steering to the right side of a stretcher.

25. Lock the radiator in working position. To do this, insert cotter pins through the holes in the rear of the front cross member of the engine compartment into the elements of the upper radiator supports. Remove the radiator support bracket bolts from the subframe. Please note that they differ in shape, like mirror images, and are marked for correct installation (see fig. 4.25, a, b). Assemble the bottom support rubber pieces, considering which side they are on, and fold them for storage.



26. Turn out bolts of a back support of the power block from a stretcher. On models with automatic transmission, a separate damper can be installed under the subframe, the bolts of which must be unscrewed to access the support fasteners. On manual transmission models, also remove the center mount bolt and remove the mount bracket bolts from the transmission.

27. Turn out the central bolt of a forward support of the power block and turn out bolts of a support from a stretcher, taking into account position of an arm of an electric socket of conducting.

28. White paint or similar (but without scratching the surface) mark the subframe and the bottom for subsequent correct installation. Remove the four support bolts from the subframe (note that they have washers of different sizes, see fig. 4.47A) and release the subframe so that it hangs on the ball joints of the lower suspension arms. Disconnect ball joints (one at a time) from knuckle nodes (chapter 10) and lower the subframe to the ground. Pull it out from under the car.

29. Marking all detachable components (see point 5) and preventing leakage of coolant, disconnect the hoses and pipes of the cooling system as follows (see chapter 3 for details):
  • A) Remove the upper radiator hose.
  • b) Remove the hose (heater), going from the thermostat to the fitting located on the partition of the engine compartment.

  • and) On models without an air conditioning system, secure the radiator by moving it as far forward as possible from its operating position. On models with an air conditioning system, remove the radiator assembly (chapter 3).

30. On models with an air conditioning system, disconnect the compressor wiring connector and remove the compressor bolts from the engine (see fig. 4.30). Fix the compressor as far as possible from the power unit without disconnecting the system hoses.

Warning: Do not disconnect refrigerant hoses.




31. On models with a manual transmission, disconnect the drive shafts from the transmission as follows (see chapter 8 for details):
  • A) Turn away nuts of fastening of the bearing of a support of the right input shaft and remove a heat-insulating shield.
  • b) Pull the right drive shaft out of the transmission. Get ready to fix the leaks.
  • V) Lock the drive shaft away from the power unit. Remember that the assembly will need to be lowered out of the vehicle and note that the inner joint must not be rotated more than 18°.
  • G) Pull the left drive shaft out of the transmission. Get ready to fix the leaks. Lock the shaft away from the transmission and ensure that the inner pivot does not rotate more than 18°.

32. On models with automatic transmission, follow these instructions (if necessary, see chapter 7B and 8):
  • A) Remove the center bolt and then remove the power unit rear support bracket bolts from the transmission.
  • b) Disconnect the transmission radiator line from the rear of the transmission and secure it away from the transmission.
  • V) Pull the left drive shaft out of the transmission. Get ready to fix the leaks.

  • e) Pull the right drive shaft out of the transmission. Get ready to fix the leaks. Lock the shaft away from the transmission and ensure that the inner pivot does not rotate more than 18°.
  • and) Disconnect the transmission radiator line from the front of the transmission and secure the line away from the transmission.

33. Now the power block rests only on the left and right supports along with all the components that normally connect it to other vehicle systems and which are now disconnected or removed and fixed away from the power block. Check again and make sure everything is done correctly. Then make sure that the body is securely supported, sufficient to perform the operation of extracting the power unit through the bottom.

34. Hang the power block on the lugs located on the head of the block. Turn out six nuts of fastening of an arm of the right support, and then three nuts of fastening of an arm of the left support.

Warning: If the vehicle or power unit is supported only by a jack or other lifting device, do not work under the power unit or vehicle!


35. Lower the power block to the ground and pull it out from under the car (see fig. 4.35).



Separation


36. Separate the transmission from the engine, taking into account the instructions in chapter 7.

37. After removing the power unit, check its supports and replace them if damaged or worn. Also check the condition of all coolant hoses as well as vacuum hoses and lines (Chapter 1). All components that are normally hidden can now be carefully inspected and replaced if found to be faulty. On models with a manual transmission, it makes sense to disassemble the clutch components (chapter 6). When performing an overhaul of the engine, it makes sense to replace the entire clutch assembly. Check the status of all components (such as transmission sleeves), that were dislodged when removed, and replace any that are damaged or worn.

Installation


38. Installation - in the reverse order of removal, taking into account the following. Tighten all fasteners to the required torque. If in the Technical requirements of the chapters 2A and 2B torque requirement for any connection is not specified, refer to the Specifications in the relevant chapter of this book.

39. In addition to the instructions in #37, always replace any o-rings and self-locking nuts removed during removal.

40. If the wiring is fixed with ties that need to be untied when removed, then new ties must be prepared for installation.

41. After completing the repair, install the transmission on the engine (chapter 7).

42. Move the power unit under the car, connect it to the lifting device and lift the unit to the installation site so that the right and left supports of the unit can be restored. Then lightly tighten the nuts. Keep the power block supported by the lifting device. Its weight should not be transferred to the supports until they are all properly installed.

43. Install drive shafts (chapter 8) using new elastic rings, as well as preventing the rotation of the internal hinges at an angle greater than the maximum. On models with manual transmission, perform this procedure in the reverse order of step 31. On models with automatic transmission, follow these instructions (chapter 7B and 8):
  • A) Install the left drive shaft.
  • b) Attach the transmission radiator lines first to the rear and then to the front side, fastening the clamps accordingly and tightening the couplings to the required torque.
  • V) Install the right drive shaft to the transmission. Install the heat shield. Tighten the support bearing nuts to the required torque.
  • G) Install the power unit rear support bracket to the transmission. Torque tighten the bolts, then install the support and lightly tighten the center bolt.

44. On models with an air conditioning system, do not forget to install a compressor. Tighten the bolts to the required torque and connect its electrical connector.

45. Given the observations and marks made during removal, install the cooling system hoses. Where they have been disconnected or released from their latches, be sure to secure them at the appropriate time in the installation procedure. Install the radiator (if it was taken) and fix it with cotter pins in working position.

46. Bring the stretcher (each side in turn) and connect it with the ball joints of the lower suspension arms to the steering knuckles. Install the subframe bolts, making sure the washers are installed correctly, and lightly tighten the bolts.

47. Now the subframe must be placed on the body. For this, the Ford 15-097 fixture is intended, which is a pair of conical guides with places for fixing them to the subframe during its installation. But in view of the fact that the working diameter of such devices is 20.4 mm, and the corresponding holes in the subframe and body are 21 and 22 mm, respectively, when aligning the subframe, a significant gap is possible even when using regulated devices. If you do not have them, then the subframe can be exposed by eye, centering its hole relative to the body and using the marks made during removal. Another way to align the subframe is to use a tapered rod (such as a clutch centering tool) or even a high key head (right size) (see fig. 4.47, a, b).





48. Immediately after alignment of the subframe, tighten its bolts to the required torque, do not mix it. After tightening the bolts, immediately repeat the check of the position of the subframe.

49. After alignment and secure fastening of the subframe, it is necessary to accurately set the power unit for the subsequent assembly of its supports. For this, the Ford 21-172 fixture is intended. This device is bolted to the subframe instead of the power unit front support so that when the central support bolt is installed, it is held in position: 60 mm above the upper surface of the subframe with an offset of 20 mm back relative to the axes of the subframe support bolt holes. If you do not have such a device, then to perform this operation, you must make a copy of it (see fig. 4.49).



50. Attach the fixture to the subframe in place of the power unit front support and lightly tighten the center bolt. Install the power block supports in the following sequence:
  • A) Tighten nuts of the left support the demanded moment. When tightening them, the support should not swing (see fig. 4.50 a).
  • b) Tighten the four nuts securing the right support bracket to the engine to the required torque.
  • V) Using the lifting gear, slowly lower the power unit until it rests on its supports.
  • G) Tighten the two nuts securing the right support bracket to the support to the required torque. When tightening them, the support should not swing (see fig. 4.50.6).
  • d) Assemble the rear support of the power block and tighten the fasteners to the required torque. Finally, tighten the center bolt.
  • e) Install the steering gear to the subframe. If you are using a Ford underbody bolt tightener (chapter 10), please note that you will need a torque wrench that can be used to tighten counterclockwise.
  • and) Remove the special tool bolts from the front support. Then install the front support. Don't forget the wiring harness bracket. Torque tighten first the support bolts/nuts and then the central bolt (see fig. 4.50, c, d).









51. Install the lower rubber supports under the radiator with the corresponding side. Then install the radiator support brackets on the subframe (to the required position - by marks). Tighten the bolts to the required torque. Remove cotter pins and secure coolant hose connections (if necessary).

52. Install the air conditioning battery/drier (if available) on the stretcher.

53. Tighten two bolts of fastening of pipelines of a hydraulic system of a steering located on the right side of a subframe.

54. Attach the ball joint of each lower front suspension arm, as well as each end of the tie rod to the corresponding steering knuckle, and both connecting links of the stabilizer bar to the respective suspension struts. Notice the brake hose bracket attached to each link stud (chapter 10).

55. On manual transmission models, move the linkage forward, tighten its rear fasteners, and then install the linkage heat shield. Connect linkage (gear shift) with the transmission support rods and adjust the linkage to the marks made during removal (chapter 7A).

56. Install the remaining components and fasteners in the reverse order of removal.

57. Top up the engine with coolant and oil, and the transmission with working fluid (Chapter 1).

58. Start the engine and check if it runs reliably and for leaks. Stop engine and recheck fluid levels.

59. Remember that if the front suspension subframe and steering gear have been removed and installed, then it is necessary to check the alignment of the wheels and steering as soon as possible and make any necessary adjustments. This job is best left to the experts (dealers).
