• When the lock nut is loosened excessively, the idle
r pulley tilts and the correct tension adjust-
ment cannot be performed. Never loo sen it excessively (more than 45 degrees).
• Put a matching mark on the lock nut, and check turning angle with a protractor. Never visually
check the tightening angle.
2. Adjust the belt tension by turning the adjusting bolt. CAUTION:
• When checking immediately after in stallation, first adjust it to the specified value. Then, after
turning crankshaft two turns or more, re-adjust to the specified value to avoid variation in deflec-
tion between pulleys.
• When the tension adjustment is performed, the lo ck nut should be in the condition at step“2”. If
the tension adjustment is performed when the lo ck nut is loosened more than the standard, the
idler pulley tilts and the correct tens ion adjustment cannot be performed.
3. Tighten the idler pulley lock nut.
Removal and Installation INFOID:0000000004784271
REMOVAL 1. Loosen the idler pulley lock nut (A), and then adjust the belt ten- sion by turning the adjusting bolt (B).
2. Remove drive belt.
INSTALLATION 1. Pull the idler pulley in the loosening direction, and then tempo- rarily tighten the idler pulley lock nut (A) to the following torque.
NOTE:
Do not move the lock nut from the tightened position. Proceed to step “2”.
2. Install the drive belt to each pulley. CAUTION:
• Make sure that there is no oil, grease, or coolant, etc. in pulley grooves.
• Make sure that the belt is securely inside the groove on each pulley.
3. Adjust drive belt tension by turning the adjusting bolt. Refer to EM-14, " Tension Adjustment " .

• If items or work required are not covered by the
engine section, follow the procedures in the applica-
ble sections.
• Always use the support poin t 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 prepar ation for the backward shif t of center of gravity.
• For supporting points fo r lifting and jacking point at rear axle, refer to GI-38, " Garage Jack and
Safety Stand and 2-Pole Lift " .

24. Remove A/C compressor with piping connected from t
he engine. Temporarily secure it on the vehicle side
with a rope to avoid putting load on it. Refer to MTC-80, " Removal and Installation of Compressor -
MR18DE " .
25. Remove the intake manifold to prevent the hanging chain from interfering. Refer to EM-141, " Compo-
nent " .
26. Install engine slinger to cylinder head front left side (A) and rear right side (B) and support the engine position with a hoist.
27. Support engine and transaxle assembly with a hoist and secure the engine in appropriate position.
28. Use a manual lift table caddy (A) or equivalently rigid tool such as a transmission jack. Securely support bottom of the engine
and the transaxle, and simultaneously adjust hoist tension.
CAUTION:
Put a piece of wood or someth ing similar as the supporting
surface, secure a completely stable condition.
29. Remove torque rod (RH) (1), engine insulator (RH) (2) and engine bracket (RH) (3).
30. Remove engine through bolt-securing nut (C).
31. Remove the engine and the transaxle assembly from the vehicle downward by carefully operating sup- porting tools.
CAUTION:
• During the operation, make sure that no part interferes with the vehicle side.
• Before and during this lifting, alw ays check if any harnesses are left connected.
• During the removal operation, alw ays 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.
• During operation, securely suppor t the engine by placing a piece of wood under the engine oil
pan and transaxle oil pan. Securely sup port the engine slingers with a hoist.
32. Remove starter motor. Refer to SC-9 .
33. Separate the engine and the transaxle and mount the engine on a suitable engine stand. Refer to AT-232(A/T models),
CVT-182 or

6. Remove the strut attachment from strut.
INSPECTION AFTER DISASSEMBLY
Strut Inspection Check the following:
• Strut for deformation, cracks or damage, and replace it if necessary.
• Piston rod for damage, uneven wear or di stortion, and replace it if necessary.
• For oil leakage, and replace it if necessary.
Strut Mounting Insulator and Rubber Parts Inspection Check strut mounting insulator for cracks and rubber part s for wear. Replace it if malfunction is detected.
Coil Spring Inspection Check coil spring for cracks, wear or damage, and replace it if necessary.
ASSEMBLY CAUTION:
Do not damage strut piston rod when installing components to strut.
1. Install the Tool (A) to strut and secure it in a vise.
CAUTION:
When installing the strut att achment to strut, wrap a shop
cloth around strut to protect it from damage. Tool number : ST35652000 ( — )

DRIVE BELT
DRIVE BELT : Checking INFOID:0000000004806005
• Inspection should be done only when engine is cold or over 30 minutes after the engine is stopped.
• Visually check belts for wear, damage, and cracks on inside and edges.
• Turn crankshaft pulley two time clockwise, and make sure tension on all pulleys is equal before doing the test.
• When measuring deflection, apply 98 N (10 kg, 22 lb) at the ( ) marked point.
• Measure the belt tension and frequency with acous tic tension gauge at the ( ) marked point.
CAUTION:
• When the tension and frequency are measured, the acoustic tension gauge should be used.
• When checking immediately after installation, first ad just it to the specified value. Then, after turning
crankshaft two turns or more, re-adjust to the sp ecified value to avoid variation in deflection
between pulleys.
DRIVE BELT : Tension Adjustment INFOID:0000000004806006
CAUTION:
• When belt is replaced with new one, adjust belt tension to the value for “New belt”, because new belt
will not fully seat in the pulley groove.
• When tension of the belt being used exceeds “Limit”, adjust it to the value for “After adjusted”.
• When installing a belt, make sure it is correctly engaged with the pulley groove.
• Never allow oil or engine coolant to get on the belt.
• Never twist or bend the belt strongly.
1. Loosen the idler pulley lock nut (A) from the tightening position with the specified torque by 45 degrees.

WARNING:
Be sure to perform this step when the engine is stopped.
• Make sure that the indicator (notch on fixed side) of drive belt auto-tensioner is within the possible use range
(A).
NOTE:
• Check the drive belt auto-tensioner indication when the engine is cold.
• When new drive belt is installed, the indicator (notch on fixed side) should be within the range (B).
• Visually check entire drive belt for wear, damage or cracks.
• If the indicator (notch on fixed side) is out of t he possible use range or belt is damaged, replace drive belt.
