Re: How difficult is it to replace the altenator on a...
The alternator is generally mounted low on the engine on the firewall side. This makes access very awkward. The work must be done both over-the-fender and from below, depending on your agility and reach. Whenever the work is to be performed from below, the vehicle must be safely supported on jackstands. If only the front is supported, the parking brake must be applied and the rear wheels firmly blocked. Once elevated, the gravel or splash shield must be removed from under the engine.
- With the ignition OFF, disconnect the negative battery cable.
- Remove the power steering pump. Refer to Suspension & Steering for the complete procedure.
- Remove the cruise control actuator but do not disconnect the actuator cable; simply move the unit out of the way with the cable attached.
- Unplug the multi-pin electrical connector.
- Remove the terminal nut and remove the wire from the terminal.
- Loosen the adjusting bolt; remove the alternator nut.
- Remove the belt from the alternator pulley.
- Remove the adjusting bolt, the lower through-bolt and the small support stay.
- Support the alternator. Remove the upper through-bolt and remove the alternator.
- If desired, remove the alternator mounting brackets.
To install:
- If the alternator brackets were removed, reinstall them. Coat the bolts with a thread sealer or liquid thread lock. Install the bracket bolts and tighten them to 36 ft. lbs. (50 Nm).
- Fit the alternator into place. Install the upper through-bolt and tighten it to 33 ft. lbs. (45 Nm).
- Install the small stay, the lower through-bolt and the adjusting bolt. Make certain the adjusting bolt is properly installed.
- Install the belt. Install the alternator nut. Adjust the belt tension. Tighten the alternator nut to 19 ft. lbs. (26 Nm).
- Connect the wire to the terminal and tighten the nut.
- Engage the multi-pin connector to the alternator.
- Install the cruise control actuator.
- Install the power steering pump.
- Connect the negative battery cable.
It shouldn't be too dificult, but unless you have mechanic experience, you should definitely get a repair manual. Personally, I think the Haynes brand is the best- they have great descriptions, with very good photos.
