I want to do the electric fan upgrade, and want to make sure I have the electrical side handled before I attempt the mechanical side. I would go with a set of stock fans, and pin them into the ECU harness, and have the fans enabled via a Tech 2.

Referencing my alternator, I recall seeing it was rated at 140 amp. Wanted to know how this compared to what was installed by GM on the 2005+, which had electric fans.

The 2005+ models have a 160 amp alternator.

When my 2005 alternator quit, the parts house had 2 different models showing. So i bought both and matched the connector on the back. I believe the one that did not fit was a 145amp model. just check your connector on the back.
