Ford Aerostar :: Power Steering Fluid Leaking - Pump Replacement?
May 5, 2015
Proud owner here of a '96 3.0L RWD Aerostar Utility Van with about 138k miles, and leaking power steering fluid. At this point I'm replacing fluid from zero every time I have to drive it which is about once a week. I've located the leak and it seems to be coming from the pump/reservoir around the pressure hose. The hose is loose as in i can move it around a bit, but from what I've read, this is normal and the hose is supposed to be like that. I figure that at this mileage, with so much air going through the pump, all the crazy squealing and whining it does even when full, at this point it probably makes sense to replace the whole pump while I'm in there, as opposed to just doing the reservoir. Anyway, I'm planning to do this in a couple of weeks, and have some questions...
1) The pump - I've read on this forum that the best way to go on brand of the pump is Motorcraft.
2) Hoses - I'd like to replace the hoses coming out of the pump while I have this thing all taken apart, but I'm not exactly sure what parts to get. I know one is the pressure and one is the return, but there are variations of each based on the research I've done. The parts on the Napa site have different descriptions like "with switch port", "without switch port" "56in hose" "26in hose", and so on. Which ones I need, specifically the ones connecting directly to the pump? I havent been able to find anything in my research online, in Haynes, or Chiltons manuals.
3) Washers - Whether or not I replace the hoses, should I replace the washers at the connection point? Chilton's seems to recommend replacing them. Will they come with the new pump?
My local auto parts shop has the pulley remover/installer for me to rent so I've already got that squared away. I'm pretty sure I've covered all of my bases otherwise.

My car is in the shop and has a leak at the Power Steering Pump. The rubber O-ring on the Power Steering Pump Solenoid Valve (p/n 4417030120) is leaking fluid. The Solenoid Valve is ok, just the Rubber O-ring is bad, but it looks like you have to buy a complete new Solenoid Valve to get the O-ring (a lotta bucks).
I did find a Lexus Power Steering Pump rebuild kit online at, but I can't see if it includes the solenoid valve o-ring or not. Have to replace their solenoid valve o-ring?

So I have multiple issues that all seem to stem from a power steering leak. According to the dealership, the PS pump is leaking fluid onto the serpentine and timing belts causing them to swell. This in turn has something to do with the AC compressor not working but they wouldn't give me details. When I looked at the clutch wheels on the AC compressor, there seems to be a good amount of rust in between the two wheels. I can't say that I trust the dealership because the original owner was bought out by a larger group that is known to just say "replace everything". I usually do most of my own work on my 95 Tacoma, so I'm no stranger to import v6 motors.

I have a 1997 Ford Aerostar rwd with a 3.0 L v6. I would like to know how can I remove the power steering pump. Furthermore, the reason I am changing the power steering pump, is because I am changing the rack and pinon mechanism. Additionally, I found the rack filled with hydraulic fluid. If possible pictures would be a nice addition to your respond.

I have a truck that is leaking power steering fluid. I have change out the line from the bottom of the power steering fluid container, but i cant get it tight enough to stop leaking. I tighten it, and it stops for a while then starts leaking again.

I am trying to use a ford pump to power a Hydro-boost off a diesel pickup, took everything off same truck. Started it up, ran ok for 5 mins & PS pump fluid boils. No PS box in the system, just the Hydro. Seems like the fluid is not getting out of the pump & circulating either. I figure a blocked pump discharge or blockage in the Hydro. I can shoot air backwards thru the hydro, too hot to touch the pressure side. I had the outlet nut off the pump, could I have blocked the discharge when I put it back?

When replacing the power steering pump on my 2006 should I go OEM on the pump or save some money and get a Napa or aftermarket remaned unit with the pulley installed? Also, whar is the fluid capacity of the power steering system?

Across Internet is lot of examples of using pump, usually drill pump or vacuum. It seam to me that drill pump would work good for that job. Pump that attach to battery have limited amount of power and vacuum pump is manual. Look like a excellent device for transmission fluid change. Clearly no drain screw at pan. I do not think I'm fan of disconnecting return line and live empty tranny.
For example here : [URL] .....

I seem to remember a old post but I can't find it! Someone replaced the fuel pump by cutting a hole through the floor.

I have a 2003 Ford Explorer with Power Steering problems. I have read and tried all the solutions I found here, except replacing the pump. Seems like it is the pump. Oil was burnt, I flushed twice. I checked the rack and lubed as identified in another post, same jumpy hard to steer issue. Anyway, now I am trying to remove the Pump. I have removed the reservoir and am trying to remove the pump. I have the top two bolts out, but cannot get to the bottom tow bolts. How do you access them? Do I need to remove the lower radiator hose, and / or the oil filter?

We are a 2 Escape family. We have an '03 and an '05 - both 4WD and 3.0 V6. My college freshman son purchased the '05 this summer to get to and from his summer job. It has a little over 173K on the clock and it has a power steering leak, so I decided to try to tackle this one.
There is a fairly good video on YouTube on replacement of the power steering pump on an '03 - but apparently on the '05 Ford decided to relocate the pump from under the upper right engine mount to a lower location closer to the front bumper so the video is not of much use in this case.
I have searched the web and this site but cannot find any tips or instructions to replace the power steering pump on the '05. The Chilton Manual I have does not acknowledge the difference in the power steering pump location on the '05 and only provides the procedure for those Escapes where the pump is located under the upper engine mount.
I think I may be able to get better access by removing the inner fender plastic and perhaps the front bumper cover, but would really like to know the accepted procedure before I start tearing into this one.
One interesting bit of info regarding power steering fluid on these vehicles. Ford designed them to use automatic transmission fluid (Mercon) instead of power steering fluid. Initially, when I saw the leak, I thought it was a tranny line leak. Then I traced it to the front of the engine which is totally on the opposite side of the vehicle from the tranny lines.

2010, 5.4L... Noticed a small oil spot under the truck this morning. Took it into the shop after work, we lifted it up, and ran it for 15 min to see where the leak was coming from, and the truck did not leak a drop... until we turned it off. The oil would slowly leak near the power steering pump pulley. But only when the engine was not running ...

I've got the feeling wire clothes hangers, duct tape, & screw clamps may be handy,;>). there appears to be a security cage around the fitting where the hose connects to the pump.

I have power steering fluid leaking out of the bottom of the Brake master cylinder out of a round hole. Every time I pushed brakes it leaks a good amount of power steering fluid out. Why it would do this and is there a screw missing out of the hole or what?

I have a '92 Celica GT which runs perfect except for the Overheating problem, the Power Steering problem isn't a big deal for me, Before I owned a '88 Chevy Beretta GT and after that a 94' Pontiac Grand AM SE. They were both pretty crappy.
But I need to figure out why it's overheating like this, Me and my stepdad did a raidator flush on it and it didn't work at all, The fan works fine, but I will be driving it and will have to pull over quite often to let it cool down and put water in it, I've stopped using coolant because I'm wasting too much money on it, and it does the same as the water, I know for a fact it isn't leaking, it acts like it's burning it up or something. I'm not even speeding in it or anything, what's causing the overheating.
I thought it was the radiator but I was told it wasn't, then I noticed the radiator cap was spurting out water and took it to the auto parts store to get it replaced and it didn't work, They told me somebody before I owned it switched the radiator from a 91 Camry? or something like that. That is the cap he replaced it with anyways because the cap for a '92 Celica didn't fit, it was too big. But the car ran perfect when I first got it around December, no problems at all, It just started overheating like this about a month ago.

I have a 94 Celica 2.2. I'm having issues with power steering fluid leaking from reservoir cap. I replaced the cap due to the old ones seal had dry rotted and dip stick was broke off, also replaced the 2 small short hoses and new clamps. The return hose is working right and the high pressure hose seems to be working right. None of the hoses are leaking but pressure is building up and pushing fluid out the reservoir cap. What else could be the problem to cause this??

Bought a 98 last week and noticed an issue a couple of days ago. The car seems to be leaking power steering fluid from right in front of passenger front tire. Looks like it's coming down from somewhere behind the bumper, just not sure what line are over there. I had to replace one of the clamps on the line below the ps bottle and it seemed to be fine for 2 days.
The weird part is that it doesn't seem steady. I had the car parked in one spot for an hour the first time I noticed the problem and the wet spot was about a foot in diameter. But then I drove the car last night and left it parked in the driveway for hours and nothing. This morning when I was leaving there was a puddle about 4" in diameter.
