ENGINE MAINTENANCE (YD22DDTI) PFP:00100
Checking Drive BeltsELS000CC

Before inspecting the engine, make sure the engine has cooled
down; wait approximately 30 minutes after the engine has been
stopped.

Visually inspect all belts for wear, damage or cracks on contact-
ing surfaces and edge areas.

When measuring deflection, apply 98 N (10 kg, 22 lb) at the
marked point ( ).
CAUTION:

When checking belt deflection immediately after installa-
tion, first adjust it to the specified value. Then, after turn-
ing the crankshaft two turns or more, re-adjust to the
specified value to avoid variation in deflection between
pulleys.

Tighten idler pulley lock nut by hand and measure deflection without looseness.
Belt Deflection:
*: When engine is cold.
Tension AdjustmentELS000K5
Adjust belts with the parts shown below.
CAUTION:

When a new belt is installed as a replacement, adjust it to the specified value under “New” value
because of insufficient adaptability with pulley grooves.

If the belt deflection of the current belt is out of the “Limit for re-adjusting”, adjust to the
“Adjusted” value.

When checking belt deflection immediately after installation, first adjust it to the specified value.
Then, after turning crankshaft two turns or more, re-adjust it to the specified value to avoid varia-
tion in deflection between pulleys.

Make sure the belts are fully fitted into the pulley grooves during installation.

Handle with care to avoid smearing the belts with engine oil or engine coolant etc.

Do not twist or bend the belts with strong force.

ENGINE MAINTENANCE (YD22DDTI)

A/C COMPRESSOR BELT
1. Remove RH engine undercover.
2. Loosen idler pulley lock nut (A).
3. Turn adjusting bolt (B) to adjust.

Refer to MA-29, "Checking Drive Belts" .
4. Tighten lock nut (A).
ALTERNATOR AND WATER PUMP BELT
1. Loosen adjusting lock nut (C).
2. Loosen alternator fixing bolts (D) (each on front and rear).
3. Turn adjusting bolt (E) to adjust.

Refer to MA-29, "Tension Adjustment" .
4. Tighten nut (C) and bolt (D) in this order.
Changing Engine CoolantELS000CD
WARNING:

To avoid being scalded, never change the engine coolant when the engine is hot.

Wrap a thick cloth around cap and carefully remove the cap. First, turn the cap a quarter of a turn
to release built-up pressure. Then turn the cap all the way.
DRAINING ENGINE COOLANT
1. Remove engine undercover.
2. Open radiator drain plug at the bottom of radiator, and remove
radiator cap.
CAUTION:

Be careful not to allow engine coolant to contact drive
belts.

Cover the exhaust tube heat shield to prevent from
splashing engine coolant.Nut A:
