AC port

Can someone take a pic of the port where to add refrigerant. The only port I can see is next to the power steering canister.

That's your high side... if you've got a vacuum pump that's where you'd connect your pump to and vacuum with the engine off. Your low side is behind the plenum on the drivers side IIRC, that's where you'll be charging it from. Do it with engine running and A/C on.

Yep just confirmed on mine, it's right under the strut bar, if you remove the cover right there you can access it.

Do I need to remove anything to see the charge port?

Shine a flash light right where you drivers side strut bar is and you can see it under there. Remove that cover above it.

I see it now. Dang it's buried! Is 134a the correct refrigerant?

Yep, 590g or 1.3lbs. Check the data plate on the hood for the info.

Why are you adding refrigerant? Just adding refrigerant without knowing what you're doing isn't necessarily going to be helpful.
