CVT : Removal and Installation

WARNING:

  • Situate the vehicle on a flat and solid surface.
  • Place chocks at front and back of rear wheels.
  • Attach proper slingers and bolts described in PARTS CATALOG if engine slingers are not equipped.

CAUTION:

  • Always be careful to work safely, avoid forceful or uninstructed operations.
  • Do not start working until exhaust system and coolant are cool enough.
  • If items or work required are not covered by the engine section, refer to the applicable sections.
  • Always use the support point specified for lifting.
  • Use either 2-pole lift type or separate type lift as best you can. If board-on type is used for unavoidable reasons, support at the rear axle jacking point with a transmission jack or similar tool before starting work, in preparation for the backward shift of center of gravity.
  • For supporting points for lifting and jacking point at rear axle, refer to GI-31, "Garage Jack and Safety Stand and 2-Pole Lift".

NOTE:

When removing components such as hoses, tubes/lines, etc., cap or plug openings to prevent fluid from spilling.

  3. Preparation for the separation work of transaxle is as follows:
  • Remove transaxle joint bolts which pierce at oil pan (upper) lower rear side. Refer to EM-33, "Exploded View".
  1. Install engine slinger to front cover front (LH) side (A) and cylinder head rear (RH) side (B).

Slinger bolts

Front cover front (LH) side: : 32.9 NВ·m (3.4 kg-m, 24 ft-lb)

Cylinder head rear (RH) side: : 25.0 NВ·m (2.6 kg-m, 18 ft-lb)


  1. Support engine and transaxle assembly with engine lifting equipment from the top with the vehicle raised on a hoist.
  2. Use a manual lift table caddy (A) or equivalent rigid tool such as a transmission jack. Securely support bottom of the engine and the transaxle assembly.

CAUTION:

Put a piece of wood or equivalent as the supporting surface, secure a completely stable condition.


  1. Remove upper torque rod (1) and engine mounting insulator (RH) (2).


  1. Remove engine mounting insulator (LH).
  2. Carefully lower jack, or raise lift to remove the engine and the transaxle assembly. When performing work, observe the following caution.

CAUTION:

  • Check that no part interferes with the vehicle side.
  • Before and during this lifting, always check if any harnesses are left connected.
  • During the removal, always be careful to prevent the vehicle from falling off the lift due to changes in the center of gravity.
  • If necessary, support the vehicle by setting jack or suitable tool at the rear.
  1. Remove starter motor. Refer to STR-30, "Exploded View".
  2. Lift with a hoist and separate the engine from the transaxle assembly. Refer to TM-28, "Exploded View".

INSTALLATION

Installation is in the reverse order of removal.

NOTE:

Tighten all mounts to specification.

CAUTION:

  • Do not allow engine oil to get on engine mounting insulator. Be careful not to damage engine mounting insulator.
  • Check that each mounting insulator is seated properly, and tighten nuts and bolts.
  • When installation directions are specified, install parts according to the direction marks on them referring to the illustration of components. Refer to EM-86, "CVT : Exploded View".

CVT : Inspection

INSPECTION AFTER INSTALLATION

  • Before starting engine, check oil/fluid levels including engine coolant and engine oil. If less than required quantity, fill to the specified level. Refer to MA-11, "Fluids and Lubricants".
  • Use procedure below to check for fuel leakage
  • Turn ignition switch “ON” (with engine stopped). With fuel pressure applied to fuel piping, check for fuel leakage at connection points.
  • Start engine. With engine speed increased, check again for fuel leakage at connection points.
  • Run engine to check for unusual noise and vibration.

NOTE:

If hydraulic pressure inside timing chain tensioner drops after removal and installation, slack in the guide may generate a pounding noise during and just after engine start. However, this is normal. Noise will stop after hydraulic pressure rises.

  • Warm up engine thoroughly to check there is no leakage of fuel, exhaust gases, or any oil/fluids including engine oil and engine coolant.
  • Bleed air from lines and hoses of applicable lines, such as in cooling system.
  • After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to the specified level, if necessary.
  • Summary of the inspection items:

*: Power steering fluid, brake fluid, etc.
