RR Power steering pump

1152 Views 14 Replies 9 Participants Last post by  jtsmith
I have 93 Cougar with a leaking power steering pump. When I bought the car the PSP was full(Yes they filled it before I got there) but after sitting for a couple of weeks, it has all drained out totally. Because of this I believe it's the low pressure side that has leaked out underneath the pump. I'm not too bad with a wrench but it's been a while since I've worked on a Merc. I've removed a couple of bolts but there seems to be another bolt unaccounted for, so my question is, what is required to remove the PSP? and I'm hoping the AC compressor doesn't have to come out.:confused:

There are three bolts holding the pump onto the bracket. In order to get to them, you must remove the PSP pulley with a pulley removal tool.

Thanks for the heads up, I'll look for one pully remover to get er dun.
it is almost that easy...........the bolts used to secure the pump are a torx head T-50 (they may be T-55) so you will need that socket also.
Auto Zone has the pulley removal tool available as a free loaner. Other parts stores may also offer it.
if youre going to all the trouble to pull the pump, I think I'd replace it, you don't know how many times its been run dry

I'd think along those lines but if it's just a cracked hose, I'd rather just change the hose.
Now I see I have another problem. To get any kind of tool on the P/S pulley, the fan shroud has to be removed, and to remove that I have to remove the fan blades. Any suggestions on how to crack the nut holding the fan on?
check and see if one of your local parts store has the proper tool for the job, sometimes they'll lend them, I probably should have told you the shroud needs to come out. That fan is a ***ch to get loose sometimes, especialy if its been on there for a while.

Heh yah.. and then trying to get it started again is a PITA too at times... If only the Fan shroud was a 2 piece design like on some GMC by-products
I just wanted to thank you gents in the assistance of my R & R power steering pump.
The operation was a success, especially with the free tool rental from Auto Zone,
and a friend with the proper tool to remove the fan. Yes it was a ROYAL PITA to install the fan again, my hand and arm still hurt. I Just wanted to document that the removal of the fan is Counterclockwise, since that is the direction of the engine's rotation. So put a wrench on it and wack away.

Thanks again,
Ed

Excuse me--
Why will a normal wheel puller not work?

I am starting this replacement today--however the nearest AZ or Orielly's is in the next town, 10 miles away. I'd like to start right away without the delay of the trip OOT.
Thanks

If you try it, $5.00 says you'll damage the pulley.

ok
Sorry, i jumped into the best thread for this subject I could find--
I am working on a '97-it threw the belt about 2 years ago--then developed a leak shortly after. The leak stopped after some lucas PS fix
While we were in there changing the oilf filter adapter gasket (4.6l) we decided to change pump since it is in the way--it will come out with the pulley attatched.
The belt fragments had bent this pulley, so we are waiting for the new one.
I think any wobble in the pulley is not tolerable-it will strain the shaft and cause premature pump seal failure.
BTW--you need the special puller for this pulley--it is a tapered fit, very tight. I didn't see a way around it , so didn't try--
