Loosen alternator on pass side then loosen AC pump on driver side. Not difficult. I don't know witch pump but when you get it off bring to parts shop with any engine info you have.

Match the water pump to the 8th digit of your VIN.

What is that 8th digit?

That's exactly why I mentioned for him to use "the car" - the only thing that is an "add" is the TPI!! Accessory drive is original!!
