Lexus SC430 :: Rubber O-ring On Power Steering Pump Solenoid Valve Leaking Fluid
Apr 4, 2015
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?

I have a 98 Subaru Legacy Outback with 133K miles. It was leaking from the power steering pump and valve cover gaskets. My husband replaced the passenger-side valve cover gasket (which involved removing the air box) and the power steering pump (which required removing the alternator). When we put the car back together and reconnected the battery, it no longer starts! It "clicks" once but won't turn-over. The car does not have an alarm system (but it was an option on this model). We've tried jumping it. The battery is about 14 months old. The alternator is about 10 months old and the starter was replaced about 10 months ago too. We've double checked the wires that were disconnected and don't think we've missed anything.

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.

I was replacing the oil in the transfer case and came across this under the passenger side. Power steering rack seems to be leaking through the rubber boot, but I have not noticed anything on the garage floor in recent months...
Can the boot itself be replaced? I hate to think the whole system needs to be replaced.

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 lexus rx 330. Pump started making noise and low on fluid. We replaced all the belts and new pump. After installing new pump it was leaking from fill cup cap when driving also making a lot of noise on cold start. Mechanic said new pump was bad so we put in another one. Car ran fine as soon as we put it in and bleed good. Following morning again a lot of noise on cold start and noise goes away about 10 minutes but again small amount of fluid leaking from cap on fill cup. I replaced the rubber ring on cap to get a tight seal but again nothing.

Either one of my power steering hoses or the gear box is leaking on my 93 Ranger. It appeared the return hose was leaking where the rubber meets the crimp. So I decided I would go ahead and change the return and pressure hose to see if it stops the leak. It was a disaster. It's 2.3L manual transmission 4x2. I got the return hose off ok. I put the wrong size wrench on the pressure hose fitting at the pump but thought it was loosening but it was rounding the nut off. So I couldn't even change that hose. I installed the new return hose and retightened the pressure hose at the gear box.
Well it was a pain getting the flare fittings of the hoses into the steering box so I could tightened the flare nut down. I finally got them tightened, I think, but then when I started the engine fluid shot out of there like a water hose. It's coming from the fittings at the gear box that I thought were tightened. I reloosened and retightened them again and still it's shooting out everywhere. There is so little room getting a wrench on the hose fittings, it was slow going. What do you need to remove in order to get a good straight shot and installing these flare nut fittings and tightening them down right? If I remove the pump will it be easier to install the hoses on the gear box? I have to remove the pump now to change the pressure hose.

I have owned 64 Mercury Monterey since new. Power steering control valve was leaking. I replaced the original, control valve, power cylinder, pump and hoses with new parts. I bled system and now I do not have power steering at low speed as in when trying to park the car. Parts store exchanged new parts thinking one may hjave been defective and still same problem except this time the control valve leaked all the fluid from the cap that covers the spool adjusting nut. I don't know what to do??

I noticed that the power steering fluid is leaking bad from a weird spot under the car, it looks like it is coming directly under the drivers seat but I can see any lines. It's an 02 Santa fe ....

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 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.

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.

We have a 99 Honda Civic that just started leaking power steering fluid. My mother was out with it when it suddenly ran dry so she bought some power steering fluid from autozone unaware that Hondas aren't supposed to use generic power steering fluid. Now the reservoir is dry again, the fluid leaked out in a matter of hours, so what kind of damage could the non Honda fluid have caused? Also, what could be causing a leak that fast?

We have a 2001 VW Golf w/100K+ miles and the power steering fluid's leaking. Mechanic says a new rack/pinion and steering gear is needed. The estimate is $1K which troubles us because of the market value of the car isn't great. So, in the meantime, I tried "Lucas Stop Leak" and it seems to work (when the fluid was completely empty, it was making that loud screeching noise). Seeing that this is a 2nd "back-up" car, my questions are these:
1) Is it a bad idea to use Lucas (topping it off w/VW-approved steering fluid)? We rather donate the car than than to pay for the repairs. Some internet searches indicate that a lot of people drive around with a bottle of Lucas in their trunk. That is, that they avoid the repairs by using Lucas
2) Is it dangerous to drive the car? I notice the alignment is off and that re-alignment is part of the repair job. Can I have the re-alignment done?

I have a 1999 Jeep Grand Cherokee which I bought used. Last oil change they told me that the power steering pump was leaking. The leak was not enough to be seen, but it did seem to make some noise every once in a while so I took it in to get a new power steering pump at the dealer. Two days after they put the new pump in, power steering fluid was pouring out on the driveway, it was a really big puddle of fluid. I had to put new fluid in to drive it five miles back to the dealer. They said that it needed a new line, they were not sure why it needed a new line, they guessed because of the high mileage, 164,000 miles.
I told them that my Mercury has 287,000 miles on it and has never had the power steering pump replaced or the line either. I have driven most every car I ever owned 300,000 miles and have never replaced a power steering pump or line. But anyway, when the Jeep was supposed to be ready, they told me that the new line blew up spraying fluid all over the shop as soon as they started the Jeep and they had to get new parts so it would take another day or two. My question is what caused the new line to blow? My thinking is there must have been something wrong with the new pump or with the installation, somehow it was outputting too much pressure, anything that could blow a new line, would blow the old line.

A few days ago I had a big PS fluid leak. Turned out the return line had been sliced a bit. I had to drive it for a couple days before I could get around to fixing it. The steering is still stiff and the pump whines. Is this an indicator that I need to replace the pump?

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?

Looking for a write-up on replacing the seals on the hose that leaks at the power steering pump? I replace them once but may of over tightened them. I pour in atf and see it dripping on drivers side of power steering pump. Can I just use regular o rings?
