I need to remove to replace the alternator?

Hello,

The alternator in the RSX is a tight fit.
However there is a fairly easy way to access it.

After you remove the drive belt, remove the power steering pump by take off two bolts that keeps it in place. No need to take off the power steering hose, that way the power steering system stays intact.
This will allow you to move the power steering pump just enough to get the alternator out.

I have attached the diagrams for your reference.

Please let me know of any questions.

Thank you.
