ENGINE, REMOVING

Note. If the engine oil must be drained because of work performed on a removed engine, it should be performed with the engine installed. If the engine hangs on the engine lateral bracket T03001, the engine is not in the installed position and less engine oil flows out.

Special tools and workshop equipment required

  1. Torque wrench (5-50 Nm) VAG 1331
  2. Torque wrench (40-200 Nm) VAG 1332
  3. Engine and transmission jack VAG 1383A
  4. Spring clip pliers VAS 5024A or hose clip pliers VAS 6340
  5. Step ladder VAS 5085
  6. Engine holder bracket T03000
  7. Hose clamps up to 25 mm dia. 3094
  8. Old oil collecting and extracting device VAG 1782
  9. Adapter set for engine and transmission support VW 540/1A
  10. M8 x 100 bolt
  11. Cable tie

Secure the engine to the engine stand. Refer to ENGINE, SECURING ON ASSEMBLY STAND .

Note. To perform the procedure, the ground cable must be disconnected from the battery. Check whether a coded radio is installed. If so, obtain the anti-theft code beforehand. The engine is removed downward together with the transmission. All cable ties which are opened or cut off when removing the engine, they must be replaced in the same position when installing the engine. Seal off the removed fuel, ventilation and vacuum lines so no dirt enters the system. Leave the key in the ignition lock to prevent the steering wheel from locking.

CAUTIONWhen doing any repair work, especially in the engine compartment, pay attention to the following due to clearance issues: Route lines of all types (for example, fuel, hydraulic, Evaporative Emission (EVAP) system, coolant, refrigerant, brake fluid and vacuum) and electrical wiring so that the original path is followed. To prevent damage to the lines, make sure there is sufficient clearance to all moving or hot components.
