Drive Belt: Testing and Inspection

WARNING: All inspection and replacement are to be performed with ENGINE NOT RUNNING.

WATER PUMP AND GENERATOR DRIVE BELT INSPECTION (G16 AND H25 ENGINES)
1. Disconnect negative (-) cable at battery.
2. Inspect belt for cracks, cuts, deformation, wear and cleanliness. If any defect exists, replace.
Check belt for tension.

Water pump and generator belt tension "a":
6 - 8 mm (0.24 - 0.32 in.) deflection for G16 engine
9 - 11 mm (0.35 - 0.43 in.) deflection for H25 engine
under 100 N, 10 kg or 22 lb pressure

NOTE: When replacing belt with a new one, adjust belt tension to 5 - 6 mm (0.20 - 0.24 in.) for G16 engine, 7 - 9 mm (0.28 - 0.35 in.) for H25 engine.

3. If belt is too tight or too loose, adjust it to specification by adjusting alternator position.
4. Tighten alternator adjusting bolt and pivot bolts.
5. Connect negative (-) cable to battery.




WATER PUMP, GENERATOR, POWER STEERING AND/OR A/C COMPRESSOR (IF EQUIPPED) DRIVE BELT INSPECTION (J20 ENGINE)
1. Disconnect negative (-) cable at battery.
2. Inspect belt for cracks, cuts, deformation, wear and cleanliness. If any of above conditions are found, replace. Also, check belt for tension.

Tension indicator "B" should be the right of indicator "A" as shown in the figure. If indicator "B" is found to the left of indicator "A", replace generator belt.




ENGINE COOLING FAN DRIVE BELT INSPECTION (J20 ENGINE)
1. Disconnect negative (-) cable at battery.
2. Inspect belt for cracks, cuts, deformation, wear and cleanliness. If any defect exists, replace. Check belt for tension.

Cooling fan belt tension "a":
5 - 7 mm (0.20 - 0.27 in.) deflection under 100 N (10 kg, 22 lb) pressure.

NOTE: When replacing belt with a new one, adjust belt deflection to 4 - 5 mm (0.16 - 0.19 in.)

3. If the belt is too tight or too loose, adjust it to specification by adjusting cooling fan pulley position.
4. Tighten adjusting bolt and pivot bolt.
5. Connect negative (-) cable at battery.




POWER STEERING PUMP AND/OR A/C COMPRESSOR DRIVE BELTS (IF EQUIPPED) INSPECTION (G16 AND H25 ENGINES)
1. Disconnect negative (-) cable at battery.
2. Inspect belt for cracks, cuts, deformation, wear and cleanliness. If any detect exists, replace.
Check belt for tension.
If belt tension is out of above specification, adjust it.

Power steering pump and/or A/C compressor drive belt tension (G16 and H25 engines)
(deflection under 100 N (10 kg, 22 lb) pressure)
"a" :6 - 9 mm (0.24 - 0.35 in.)
"b" :4 - 7 mm (0.16 - 0.28 in.)

3. Connect negative (-) cable to battery.
