Alternator Relocation to avoid frame rail

Be careful using 2010 model year for info. The 6.1 carried past the introduction of the 2009 vvt engines, and the 6.1 was NEVER vvt.

I would expect any non vvt car engine to have one belt path, and the vvt car engines to have another.

The 6.1 hemi throws off some search engines, and/or customers get themselves in trouble assuming a 2010 water pump or damper is instantly one from a vvt.

Agreed. I just know of people that had issues when working on 5.7’s and that the early ones in the Challengers use different parts than the later ones. This was from a Challenger forum where a guy was complaining about the fact that his ‘10 caused him all kinds of grief.

Based on RockAuto, the 2009 6.1 uses the same water pump as the ‘08 and older 5.7. The 2009 and 2010 5.7 uses a different water pump than the 6.1 and is only applicable to those years, and the 2011+ 5.7 uses a different pump. At the same time, the alternator for a 5.7 works for ‘08-10, crossing over the VVT change.

Based on that, I believe when the VVT motor was first designed, the pulley spacing was maintained with the earlier non-VVT motor even though all the parts are different. When the 6.4 was released, the pulley spacing changed for some reason and the change was applied to the 5.7 at the same time. So the ‘09 and ‘10 5.7 is kind of a bastard for parts.
