Inspection for Leaks
The following are procedures for checking fluids leak, lubricates leak and exhaust gases leak.
• 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
.
• 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 leak-
age 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/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:
*: Transmission/transaxle fluid, power steering fluid, brake fluid, etc.

INFOID:0000000005988206
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.
• Never 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 unavoid-
able 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.

3.
Remove rear torque rod (1).
4.
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
.
Removal
1.
Use a instruction lift table caddy (commercial service tool) (A) or
equivalently rigid tool such as a transmission jack. Securely sup-
port bottom of the engine and the transaxle assembly.
CAUTION:
Put a piece of wood or an equivalent as the supporting sur-
face, secure a completely stable condition.
2.
Remove engine mounting bracket (RH) (2), and engine mount-
ing insulator (RH) (1).
3.
Remove engine mounting through bolt-securing nut (C).
4.
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.
