Hello,
It's been a long time to post here. I visited this forum almost every day though.

My 2005 S-type V6 3.0 base was parked my garage for a while because I purchased a daily car(Prius) last year. Recently, I'm renewing my s-type(oil change, filters change(cabin,air,oil,fuel), paint, brake pad etc...). Then I found oil leak from the power steering part. I lifted my car and cleaned every oil leak spot with the cleaner. After idling 20 min, I took some pictures. I see oil at the connector of the hose from rack to pump(red circle).

I researched about steering oil leak on the forum and found some posts, however, they were not same as my case. The picture shows me the leak might be from the power steering pump or the hose from pump(metal one, right above the red circle). But I'm not sure...



Here is shot from the top. there's no leak found found from this pic(there was oil spot before I cleaned), So not from the steering oil reservoir.




Did anyone have this leak before? Please help.

 

I am not recalling that particular hose on our '05, 3.0. Do you recall the color of the oil?

As I recall once the belly pan is removed, the vehicle up in the air (jack stands/lift) you can get a pretty good view of the entire underneath What I am getting at here are you sure the valve cover seal or the oil pan is not the culprit? I replaced both valve cover seals and the oil pan seal some years ago as they leaked down onto the PS hoses making them look like they were leaking.

 

Thanks for your comment, Rick. But the color of oil from the leak was pink. The valve cover seal or the oil pan you talked is engine oil, is it?

 

Yes it was engine oil. Pink is most likely PS fluid as you expected.

Like you mentioned, I to do not recall to many threads here about your drip. Here's your time to shine, take pics and post as you repair, should not be that difficult to figure out.

 

I will update my progress later to this post. BTW, Big Thanks to you, Rick. I got AC compressor and many other works done by your post.

 

I have had this problem. The fact is, there is no seal there it is just metal tube pushed into a metal hole. It was fixed by using special glue to create a permanent and tight connection between the two parts.

 

I'm glad you fixed this problem, leaping cat. Do you mean special glue as JB weld or a Fast Steel?

 

Google "Seal-All" comes in a yellow tube. GREAT stuff for this type of application.

 

Sorry, I took it to a garage. And I am not familiar with brands in the USA. Guess it must be good for metal and also heat and oil resistant.

 

Thanks for your advise, Rick and leaping cat. I just came back from my local mechanic for getting an advise. He said the metal connector is a part of whole pump assemble, cannot be apart. He also mentioned that I need to change an entire pump. I will try to take the pump out this weekend and see the mechanic is right or not.

 

That connection is a factory press fit. I would never try to reseal it. That will only be a short term fix.

But we are lucky because this pump is used on a lot of Jaguars and most importantly the Lincoln LS. So P/S pumps at least in the US are only between $60-$90. Just replace the pump. It's old and has a lot of miles on it.

Hello, tbird6. Thanks for your comment. It's great idea to replace the whole pump because I thought I should take the pump out anyway. I found some re-manufactured pumps at Ebay around $120-170. Where can I buy the pump at $60-$90?

 

Go to Rock Auto and search for the Lincoln LS part. It has pictures. It's about $86-$238.

Then check the Jaguar S Type. It also has pictures but is about $100-$300!

Look real close at the pictures because they are the same pump! I have a 2003 Lincoln LS and a 2005 Jaguar "R" and have had both pumps out and side by side.

If you are still unsure remove your old pump and go to O'riellys and match your pump up to the LS one. Other parts stores also carry them but they may need to order it in first.

So call ahead and have one waiting before you remove the old one.

Thank you so much about all these info, tbird. That is a good idea about ordering the re-manufactured pump before I take the old one out. I will order one soon.

 

Good but remember you owe us to come back and tell how it worked out as things change all the time and I did my pump swap out over a year ago.

Sure! I'll update soon,tbird. Thanks again

 

Okay. I finally replaced the power steering pump. Here's summary.

1. Remove the air cleaner.










2. Remove the accessory drive belt.



there's squre hole. push to the left and the belt will loose.





3. Remove the left-hand front wheel and tire.

4. Remove the air deflector.



5. Reposition the splash shield. Remove the splash shield retaining clip.
(I still don't understand what this part is....I skipped..lol)



6. Remove the power steering pump lower retaining bolts. (I used 10mm for all 4 bolts)



Like this






I realized the right bottom bolt(Red circle above) does not exist. So Basically, the power steering pump was held by only three bolts. Is this normal? Anyway...

7. Lower the vehicle.

8. CAUTION: Cap the power steering line to prevent loses of fluid and dirt ingress.
CAUTION: If power steering fluid comes into contact with the paintwork, the affected area must be immediately washed down with cold water.
NOTE: Drain the fluid into a suitable container.
Disconnect the power steering reservoir to power steering pump supply line.



(Squeeze the clamp and push out. I used a nipper to do this. Remember this hose is from the reservoir so steering oil will immediately drain. You will need to be prepared for this)



9. CAUTION: Cap the power steering lines to prevent loses of fluid and dirt ingress.
CAUTION: If power steering fluid comes into contact with the paintwork, the affected area must be immediately washed down with cold water.
NOTE: Drain the fluid into a suitable container.
Disconnect the power steering pump to steering gear suppy line. Remove and discard the O-ring seal.



(oils will come out, however, not much. you can just let it go. Use 5/8 open wrench as below)





10. Remove the power steering pump.




Installation
1. NOTE: Install a new O-ring seal.
To install, reverse the removal procedure. (steering gear suppy line -->Hose from Rack-->upper bolts-->bottom bolts
3. Make sure you order the pump with the pulley, otherwise, you will have to pull the pulley from the old one and install to the new one. This procedure will be a pain in the ***.








4. Refill the oil




Overall, this takes 5-6 hrs. Thanks for reading.

 

BTW, I bought the pump from Rock Auto for $100, and I will get $30 back when I return the old pump. total $80 including shipping and returning shipping fee(Rock Auto is located in Phoenix,AZ. so Shipping was like $6 for me). Thanks, tbird6.

edit : for lincoln ls pump that tbird6 mentioned, it is $75 and the core returned is $35. So if you can take the risk, the total cost will be $40 for replacing the pump. I did not order the lincoln pump because this might be the trouble when something goes wrong and needs to be returned or exchanged. $80 tot is still cheap enough for the pump replacement.
