8. Check battery state of charge. See Check State of
Charge.
9. Replace battery if necessary. See Battery
Replacement.
NOTE: On 2.5L models, start ten screws to install lou-
vered air intake panel. Alternately tighten screws to 90
in-lbs (10 Nm) using a crosswise pattern.
Check Fluid Level
Check fluid level of unsealed batteries. If necessary, fill
with distilled water only. DO NOT use tap water.
Check State of Charge
Check state of charge using a digital multimeter. Charge
and test if state of charge is below manufacturer's recom-
mendations. Replace battery if necessary.
Battery Replacement
Removal
1. See Figure 5-11. Remove negative battery cable
(black) (B) from negative (-) battery terminal.
2. Remove positive battery cable (red) (A) from posi-
tive (+) battery terminal.
3. See Figure 5-12. Install rubber protective cover
(C) over positive (+) battery terminal.
Figure 5-12. Remove/Install Battery
4. Loosen two screws with nylon washers to release
battery hold-down clamp from battery tray, or
loosen strap and position away from tray.
5. Grasp battery strap (D) next to positive (+) battery
terminal, and lift battery.
6. When battery tilts sideways, remove from opening.
7. Remove rubber protective cover from positive (+)
battery terminal.
Installation
NOTE: Always connect positive battery cable first. If pos-
itive battery cable should contact ground with negative
battery cable installed, resulting sparks may cause a bat-
tery explosion.
1. See Figure 5-12. Install rubber protective cover
(C) over positive (+) battery terminal.
2. Grasp battery strap (D) next to positive (+) battery
terminal, and lift battery.
3. When battery tilts sideways, insert into opening.
4. Return battery to horizontal position while sliding it
onto battery tray.
5. Tighten two screws with nylon washers to secure
hold-down clamp to battery tray, or tighten strap
over top of battery.
6. Remove rubber protective cover from positive (+)
battery terminal.
7. Install battery positive battery cable to positive (+)
battery terminal.
8. Install battery negative battery cable to negative (-)
battery terminal.
Check and Adjust V-Belt
Check V-belt deflection. Too little belt deflection acceler-
ates belt wear, while too much deflection causes pulley to
idle, overheats engine, and creates a no-load condition.
Check and adjust belt deflection as follows:
1. On right side of enclosure, loosen two clamps at
each end of turbocharger exhaust outlet pipe.
Remove pipe, clamps, and rubber couplings from
engine.
2. Remove four screws with nylon washers to release
fan guard from radiator shroud.
3. Inspect belt for cracks, fraying, excessive wear, or
other damage.
4. Verify belt is free of grease and oil. Replace belt if
contaminated.
NOTE: Use a solution of soap and warm water to clean
pulleys, if necessary. Avoid use of solvents, but if used,
always follow by a soap and water wash.

WARNING
Explosion. Batteries emit explosive gases.
Always connect positive battery cable first to
avoid spark. Failure to do so could result in
death or serious injury.

CAUTION
Equipment damage. Do not make battery
connections in reverse. Doing so will result
in equipment damage.
