Great aftermarket replacement - perfect for my 2005 Odyssey. It took about 1 1/2 hours to complete the renovation with two people working the driveway. You will need Honda P/S fluid, 14mm and 9/16 wrenches and a 10mm socket, and other metric or adjustable wrenches. Supplied with a new o-ring for the top fitting that attaches to the P/S pump and a new o-ring for the pressure switch. Also includes a plastic insert to cover the bottom nut hole at the top of the P/S post to keep the P/S fluid from spilling after you remove the 14mm nut (at least that's what I used for that). I removed the old one first. top clamp, bottom clamps, 14mm nut (insert the included plug quickly when removing the nut to save fluid per second). Then disconnect the electrical connector from the pressure switch. Finally, remove the two screws and fitting from the top of the P/S pump (place a can under the flare nut to catch the P/S fluid that drains from the old hose when you open the top fitting) . Delete the old part. You will need to remove and reuse the pressure switch (put a new greased o-ring on the pressure switch) and cut the three rubber bushings off the old part, remove and reuse. The upper sleeve can be cut anywhere. I cut the two bottom bushings on their flat sides at their seams. After installing the hose, connecting the electrical connector to the pressure switch, and finger tightening the flare nut, I reinstalled the bottom bushings and loosely tightened the bottom clamps. Then I installed the top bushing and clamped the hose without connecting it. I loosely installed the top connector by tightening the bolts on the pump p/s and then attaching the top bushing and clamp. Then tighten all fittings and clamps, starting with the union nut, using a 9/16 socket wrench. Finally p / s liquid poured. Don't forget to lubricate the new o-rings with P/S fluid before installing them. You will need Honda P/S fluid - I used about 8 ounces (2/3 of a bottle) but how much you need depends on how much fluid you dump before plugging the bottom nut hole. I bought three bottles - just in case. 10mm screws are used for the top connection and clamps. You will need two wrenches - 14mm to remove the old nut and 9/16 to install the new nut. Yes, you read it right. The original Honda is 14mm and the replacement is 9/16. Hope that helps.
