2006 8.1 alternator question

[Idaho5_0]

I just ordered a 2006 k 3500 Silverado with the 8.1. Because I waited so long in the model year to order, certain options are no longer available. One is the 145 amp alternator in place of the standard 105 amp.

Can I replace the 105 amp with a 145 amp alternator when I get it? If so, does anything else need to be replaced as well?

You may possibly need a new alternator belt if the pulley size is diferent on the 145 amp alternator. Before ordering the larger alternator, you need to make sure that the wiring connectors are the same (they should be).

 

If your truck is equipped with the factory tow pacakage, it should alutomatically come with a larger ouput alternator. In fact, 3500 series trucks are often used for towing large trailers and 5th wheels with lots of clearance lights on them, so a large alternator is necessary.

 

Note: I believe that they will give you the larger alternator with the snow plow prep package. Did you order that package? It is worth the money on a heavy duty truck I would have been cheaper than buying a new 145 amp alternator separately.
