REMOVAL & INSTALLATION



In the process of removing the engine, you will come across a number of steps which call for the removal of a separate component or system, such as "disconnect the exhaust system" or "remove the radiator". In most instances, a detailed removal procedure can be found elsewhere in this guide.

It is virtually impossible to list each individual wire and hose which must be disconnected, simply because so many different model and engine combinations have been manufactured. Careful observation and common sense are the best possible approaches to any repair procedure.

Removal and installation of the engine can be made easier if you follow these basic points:



If you have to drain any of the fluids, use a suitable container.
 
Always tag any wires or hoses and, if possible, the components they came from before disconnecting them.
 
Because there are so many bolts and fasteners involved, store and label the retainers from components separately in muffin pans, jars or coffee cans. This will prevent confusion during installation.
 
After unbolting the transmission or transaxle, always make sure it is properly supported.
 
If it is necessary to disconnect the air conditioning system, have this service performed by a qualified technician using a recovery/recycling station. If the system does not have to be disconnected, unbolt the compressor and set it aside.
 
When unbolting the engine mounts, always make sure the engine is properly supported. When removing the engine, make sure that any lifting devices are properly attached to the engine. It is recommended that if your engine is supplied with lifting hooks, your lifting apparatus be attached to them.
 
Lift the engine from its compartment slowly, checking that no hoses, wires or other components are still connected.
 
After the engine is clear of the compartment, place it on an engine stand or workbench.
 
After the engine has been removed, you can perform a partial or full teardown of the engine using the procedures outlined in this guide.
 

CRV

The engine and transaxle assembly are removed as a unit from the vehicle.

  1. Note the radio security code and station presets.
  2.

Odyssey

4-cylinder engines

The engine and transaxle are removed from the vehicle as a unit. A hydraulic lift is helpful for this procedure since the front subframe must be removed for the engine/transaxle assembly to be lowered from the vehicle. If a hydraulic lift is not available, the vehicle must raised and safely supported to allow enough clearance for the engine to be removed from underneath the vehicle.

  1. Note the radio security code and station presets.

  14.  


CAUTION
Never open, service or drain the radiator or cooling system when hot; serious burns can occur from the steam and hot coolant. Also, when draining engine coolant, keep in mind that cats and dogs are attracted to ethylene glycol antifreeze and could drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantities. Always drain coolant into a sealable container. Coolant should be reused unless it is contaminated or is several years old.

  1. Disconnect the battery cable from the fuse/relay box and ABS relay box.
  2.  
  3. Uncouple the three engine harness connectors located on the right side of the engine compartment.
  4.

  29. Disconnect the two cooler lines from the front of the transaxle case. Plug the inlet lines on the transaxle case to prevent moisture contamination.
  30.  
  31. Unbolt the A/C compressor from the side of the engine block. Do not disconnect the A/C lines. Wire the compressor to the radiator support so it's out of the work area.
  32.  
  33. Attach a chain hoist to the lifting hooks on either side of the engine block.
  34.  
  35. Raise and safely support the vehicle. Take up the slack of the chain hoist.
  36.

WARNING
The next step involves the removal of the subframe front beam. Be sure the vehicle is securely supported. Take up any slack in the chain hoist to support the weight of the engine and transaxle assembly during the subframe removal procedure.

  1. Raise the vehicle to allow access to the vehicle's underbody.
  2.  
  3. With the vehicle raised and the vehicle safely supported, take up the slack of the chain hoist attached to the engine lifting brackets to secure the engine/transmission assembly during removal of the lower front subframe.
  4.  
  5. Draw alignment marks for side-to-side and front-to-rear alignment between the subframe and the mounting points on the vehicle to ensure proper subframe alignment during reassembly.
  6.  
  7. Remove the lower front subframe mounting bolts and carefully lower the subframe down and away from the vehicle.
  8.  
  9. Secure the steering gear box to the underbody of the vehicle by using a strong rope wrapped around the passenger side of the steering gear box, and attached to the vehicle securely.
  10.  
  11. Remove the air conditioner compressor mounting bolts from the engine, and remove the air compressor without removing the air conditioner high pressure hoses. Support the compressor in such a way that is safe, and does not allow the compressor to put tension on the hoses or fittings.
  12.  
  13. Check the engine/transmission assembly and verify that all the electrical wiring, vacuum, fuel and coolant hoses are completely disconnected.
  14.  
  15. Carefully and slowly lower the engine and transmission assembly about 6 inches and check again that all the electrical wiring, vacuum, fuel and coolant hoses are completely disconnected.
  16.  
  17. Lower the engine and transmission assembly all the way down.
  18.  
  19. Once the engine and transmission assembly is completely lowered, it can be removed from underneath the vehicle.
  20.  
  21. Support the front of the vehicle with jackstands and block the rear wheels, as the front suspension has been disassembled. If the vehicle must be moved with the engine out, install the subframe and all the suspension components. Support the drive axles so they are level with the ground and can rotate freely without binding while the vehicle is moved.
  22.  
  23. To remove the transmission from the engine so the engine can be placed on a suitable engine stand, remove the intermediate shaft.
  24.  
  25. Locate the torque converter cover plate at the bottom of the transmission housing and remove the cover plate.
  26.  
  27. Rotate the engine crankshaft pulley to access the eight torque converter drive plate bolts from the bottom of the transmission housing and remove all eight drive plate bolts one at a time.
  28.  
  29. Remove the engine stiffener bolts, starter motor, and the transmission housing bolts.
  30.  
  31. Carefully separate the transmission from the engine, making sure the torque converter assembly remains in the transmission housing and is released from the engine drive plate. If the torque converter is stuck to the engine drive plate, pull it toward the transmission housing from the starter motor opening in the transmission housing.
