5sfe engine removal

  1. 1. 4A-FE & 5S-FE Engines 1. Disconnect the negative battery cable. Remove the battery. 2. Mark and remove the engine hood. Remove the engine under covers. 3. Raise and safely support the vehicle as necessary. Relieve the fuel pressure. Drain the engine oil and coolant. Remove the air cleaner assembly along with its hose and any attachments. 4. Disconnect the accelerator and throttle cables at the bracket. 5. Remove the lower cover from the relay box. Disconnect the fusible link cassette and connectors. Remove the engine relay box from the battery. 6. Remove the air conditioning relay box from the bracket. On the 5S-FE engine remove the cruise control actuator assembly. 7. Remove the coolant reservoir tank. Remove the radiator (disconnect transaxle cooling lines if so equipped) and cooling fan. 8. On the 5S-FE engine remove the two wiper arms and outside lower windshield molding. Remove the suspension upper brace. 9. On the 5S-FE engine, remove the ignition coil assembly. Disconnect the check connector, igniter connector (5S-FE engine), vacuum sensor connector and ground strap from the left front fender apron. Remove the engine wiring bracket. Disconnect the noise filter assembly.10. Mark and disconnect the vacuum hoses at the charcoal canister. Remove the charcoal canister.11. Disconnect the heater hose from the water inlet and speedometer cable.12. Disconnect the fuel hose. Recover all leaking fuel in a suitable container.13. On models with a manual transaxle, remove the clutch release cylinder and position it out of the way with the hydraulic lines still attached.14. Disconnect the shift control cables from the transaxle.15. Mark and disconnect the following hoses: vacuum sensor hose from the gas filter on the air intake chamber, brake booster vacuum hose, air conditioning vacuum hoses on air intake chamber and air conditioning hose from air pipe (4A-FE engine).16. Disconnect two cowl wire connectors and engine wire clamp from engine fender apron.17. Mark and disconnect the following engine wiring from the cabin: engine ECU connector, cowl wire connectors, air
  2. 2. conditioning amplifier connector and O/D diode connector (4A-FE engine). 18. Remove the suspension lower crossmember. 19. Disconnect the oxygen sensor connector. Remove all necessary brackets and retaining bolts. Remove the front exhaust pipe assembly. 20. On vehicles equipped with automatic transaxle, disconnect control cable from engine mounting center member. 21. Remove the front halfshaft assemblies as required from the vehicle. 22. Remove the drive belt. Unbolt the air conditioning compressor (if so equipped) and then wire it out of the way with the refrigerant lines still attached. 23. Remove the drive belt and remove the power steering pump assembly without disconnecting the pressure and return hoses. 24. Remove the engine mounting center member. 25. Remove the front engine mounting insulator and bracket. 26. Remove the rear mounting insulator and bracket. 27. Disconnect the ground wire from the fender apron. Remove the ground strap from the transaxle. 28. Remove the right and left engine mounting stay. 29. Slowly and carefully, remove the engine and transaxle assembly from the top of the vehicle. Be careful not to hit the power steering gear housing or the neutral safety switch if so equipped.To install: 30. With a suitable engine crane (always use lifting eyes for removal and installation procedures) install the removed engine/transaxle assembly in the vehicle.
