4. Label and disconnect these alternator wires:
• [AG1] and [AG2] from G terminal (1)
• [AB1] and [AB2] (SN 0160003689 & Before) or
Fusible Link Cable (SN 0160003690 & After)
from B terminal (2)
• [AD1] from D terminal (3) and
• [AW1] from W terminal (4)
5.
6. Remove the lower alternator bracket capscrew (5)
on the bottom of the alternator (6).
7. While supporting the alternator with one hand,
remove the upper alternator mounting capscrew (7).
Remove the alternator from the engine.
b. Alternator Installation
1. Position the alternator (6) and align with the upper
alternator mount on the engine bracket. Insert the
upper (“longer”) mounting capscrew (7) through the
rear mount and alternator. Loosely secure the
mounting hardware. DO NOT fully tighten the
hardware at this time.
2. Align the lower alternator mount hole with the lower
mounting tab (8) on the engine and insert the lower
mounting capscrew (5). Tighten the lower capscrew
securely and torque to 18 lb-ft (24 Nm). Fully tighten
the upper mounting capscrew (7) and torque to
18 lb-ft (24 Nm).
3. At the rear of the alternator, reattach all wires to their
proper terminals:
• [AG1] and [AG2] to G terminal (1)
• [AB1] and [AB2] (SN 0160003689 & Before) or
Fusible Link Cable (SN 0160003690 & After)
to B terminal (2)
• [AD1] to D terminal (3) and
• [AW1] to W terminal (4)
4. Place a 3/8" square drive ratchet into the square
hole on the tensioner bracket (9). Apply pressure
against the tensioner bracket and properly route the
fan belt (10) onto the alternator and engine pulleys.
Check the tensioner pulley to verify that it is pivoting
freely to provide the proper tension on the belt.
Check for proper fan belt deflection. (Refer to
appropriate Owners/Operators Manual for general
information.)
5. If the vehicle has dual batteries, connect both
negative battery cables (11 and 12) to both
batteries.
Connect the lower negative battery cable (11) to the
negative (-) terminal on the lower battery (13). Swing
the upper battery box (14) in and make sure that the
lip (15) on the upper battery box slides below the
knob (16). Secure in place with the knob (16).
