I have the car listed above and saw what you posted for a 2004 and the diagrams look identical to what I am seeing in my car. My question is, what is the best way to get the line connections at the gear? From underneath or down through the top? Any tips you could share would be appreciated.

Hi,

Unless you have a lift, I would try from the top. If the vehicle is high enough, then you would have better access from the bottom. However, check to see if you may have the easiest access if you safely lift, remove the front wheel, and go in through the inner fender.

I don't know which hose is being replaced, pressure or return, but I wanted to add the directions for an 05 just in case something is different. The attached pics will correlate with the directions. Also, and I hate to say it, it's a tight fit to remove them from the rack.

Thank you for the quick reply! I put the wrong engine type in my description though, it’s a 3.8L VIN K. Either way I think that going in from the top is easier, even if it is tight. I was going to use the same method I found for my plug wires to create some space on the back side of the engine (loosen top mounts and use a ratchet strap). I had a feeling that this project was going to be tight as I don’t have the ability to drop the subframe, I’m just planning on it taking longer. Thank you so much for the tips! I appreciate any help someone is willing to give me. Stay safe!

You are very welcome. Aaron, I just compared the pressure hose between engines and the directions are different. In fact, it tells you to remove the tire and wheel. I am going to provide those directions. I remembered having to remove the wheel, but the first set of directions didn't indicate it. It must have been a 3.8 I remembered. Regardless, here are the directions. The attached pics will correlate with the directions.
