Power Steering Pump Removal & Install on 2003 – 2007 Accord

You may have need to remove and install the same or a new power steering pump on the 2003-2007 Accord 4cyl. In my case, I needed to replace the worn pump bearing that made the engine noisier than normal. Other repairs that would require the removal and reinstall of the power steering (PS) pump on this model would be 

to replace; a worn automatic tensioner, variable timing control (VTC) filter assembly etc. Now, down to business!

Materials

  • 10mm wrench
  • 12mm wrench
  • 12mm deep socket (will make your work easier, but not an absolute)
  • long slender stick (an unwound metal wardrobe hanger is perfect)
  • Size 14mm wrench breaker bar (14mm & 17mm combination wrenches can be used in place of this. Keep reading to see how I did that)
  • Rags
  • Bottle of genuine Honda PS fluid (just in case…)

Steps

1. Locate the PS pump: This is found on the left side of the engine beside the the wiper washer fluid reservoir cap (blue). The PS fluid reservoir is marked.

2. Remove the serpentine belt: To do this you would need to relieve the tension on the belt by slackening the automatic tensioner. If you don’t have a 14mm breaker bar, attach the ring end of a 14mm combination wrench to the central 14mm bolt of the the tensioner. Then interlock the free end of the 14mm combination wrench with the ring end of the 17mm wrench (see the image for the technique). With this in place, pull to the combined wrenches/breaker bar towards the front of the vehicle. It does require a considerable amount of force. Once the tensioner idler moves backwards slide the belt off the front of it. Remember to note the routing of the serpentine belt via the various components. Make a diagram if you need to.

3. Remove the PS pump inlet  hose: Place a rag on the alternator and loosen the single 10mm bolt on the inlet line. A slight amount of PS fluid will spill.

4. Remove the PS pump outlet line: Place a rag around the outlet line, loosen the 2 10mm bolts and pull the line out. Some fluid will spill from the line and will continue to dribble. Its good practice to plug the lines. I used cellophane in my case.

5. Remove the power steering pump: The PS pump is held by just 2 12mm bolts; one in the front (beneath the pump pulley) and the other at the rear. Remove these. For the bolt in the rear, using a 12mm deep socket makes it easier. Also, unhooking the PS fluid reservoir creates the needed space for this procedure. Simply slide the reservoir up and keep aside.

Once these bolts are off, the PS pump will come out on its own (a better phrase should be “fall off” so support it as you loosen the last of the 2 bolts).

6. Re-installation: Simply follow reverse steps. A tip for the install of the serpentine belt is to install the belt on all pulleys except that of the automatic tensioner idler. You may need a slender stick or unwound wardrobe hanger to have the belt catch the crankshaft pulley. Then slacken the automatic tensioner center bolt as previously and slide the belt onto the tensioner idler. I found this simpler than trying to catch the PS pump pulley last.

Bleeding the power steering pump system of air

Air would be introduced into the PS system and if left would affect its function. To bleed, after completing your reinstall, follow these steps:

  1. Start the car and allow to idle for a few minutes with the steering wheel straight.
  2. Note the level of fluid in the PS fluid reservoir, if low, top up to the low mark.
  3. Turn the steering wheel from lock to lock. Do this a couple times. Do not hold it at the very end. Doing so will damage the pump.
  4. Allow to idle for about 5mins with the steering wheel straight.
  5. Turn off and top off the PS fluid in the reservoir to the high mark.

    I am having a hard time removing the high pressure power steering line on my 2003 Honda Accord EX 4 cylinder engine. The flare nut location is hard to get to. Not sure if I can even hack saw the line off without damaging something else in the process. What I find odd is the new line is a 16mm or 5/8. The one on the car is slightly larger (17mm i think). Should I get a flex head flare nut wrench to remove this? There is a diagram here [url]https://www.heeltoeauto.com/files/pitboard/tsxproject/004_pshose_recall_bulletin.pdf[/url] but they are not specific as to how to remove the flare nut.

    • So sorry to have delayed on this. My security software quarantined this comment as spam so I missed it.

      I know what you mean. That flare nut is damn hard to remove. How I do it is to make more room above by disconnecting the parts that are in the way. A flare wrench is fine but a thick open end spanner will do. I think it’s a size 19 or so can’t remember. For the seeming difference in diameter of the pipe, was it OEM that you got?

    Great! Now what tools do you need to replace the pulley on the new pump you are installing? The new power steering pump doesn’t come with it’s own pulley. It would be really helpful if you explained that to people. Let them know unless you have pneumatic tools and/or a pulley-holding tool, they will not be able to complete the installation themselves.

    • Very true Francis. Thanks for the compliment.

      Actually this is a build up to a subsequent post on my complete PS pump rebuild, indeed an air or pulley holder tool is required to take off the 19mm pulley bolt. But in my case, since I don’t own any of those, I placed a metal bar between the holes in the pulley to keep it from turning and then was able to loosen the bolt.
      Thanks again for highlighting that tough pulley bolt.
