Struck me a few minutes ago:

My 6.4 came without a power steering pump.

It looks like the donor car had EHPS or Electro Hydraulic Power Steering.

This is an electric pump providing the hydraulic pressure for a “regular” hydraulic assisted steering rack. Yay.

So instead of a pump my engine has an idler where the power steering pump would go on a similar engine:

You can see it very clearly on the drivers side of the motor (right side in image) above the A/C-compressor.

I know how to fix this: Mopar RL181778AB 2011-2013 Challenger with 6.4L, just like 340 USD … used ones seem to be scarce and Rockauto already has the best price for a new OEM Mopar part.

I could sink several tenthousand dollars into this thing right away. I’ll try to avoid that…
