Removing engine
Removing engine
  Note
t  Before carrying out further work, disconnect battery earth strap. Check whether a coded radio is fitted. Where necessary, check the anti-theft coding first.
t  The engine is removed forwards together with the gearbox and with mounted particle filter..
t  So that the steering wheel is not locked, keep the key in the ignition.
t  The front wheels should be removed before proceeding with the removal of the engine assembly. In this way, the vehicle may be lowered using the platform until the protection plates for the disk brakes are almost touching the ground. Thus, the most ergonomic working position is achieved for reaching the components in the engine compartment.
t  All cable ties which are opened or cut through when engine is removed must be replaced in the same position when engine is installed.
t  Some components can not be removed, or only with a great deal of difficulty, while the engine is mounted. All of the faulty or damaged components should be identified before removal and should be replaced before re-installing the engine.
t  After removing coolant or fuel lines, these must be sealed using the engine sealing plug set -VAS 6122- to prevent dirt from entering or coolant or fuel from running out.
  WARNING
When doing any repair work, especially in the engine compartment, pay attention to the following due to the cramped conditions:
t  Route all the various lines (e.g. for fuel, hydraulics, active carbon filter system, coolant, refrigerant, brake fluid and vacuum pipes and hoses) and electrical wiring so that the original positions are restored.
t  Ensure that there is sufficient clearance to all moving or hot components.
Consult the equivalence table for tools and equipment according to applicability among Seat / VW / Audi / Skoda → Chapter.
