Since it's such a common problem, here's my collection of three Power Steering Pump articles for the 4th Gen ST16X series. Enjoy :mrgreen: 1) PS Pump & Hose Removal: Note: Don't worry about the SST (below). A monkey wrench, regular crescent wrench or best of all, 17mm flare nut wrench work just as well. *Note: You may find it easier to remove/loosen the top bolt first because the bottom bolt will support the pump, keeping the weight and tension off the top bolt. A socket doesn't fit properly into that restrictive area where the PS pump top bolt lives; no clearance. I find it easier with obstruction wrenches, (like "S" or "C" shaped ones), offset box, crow's foot and/or Gear or ratcheting flex-head wrenches. A basic open-ended wrench works just as well too. 2) Tensioning the PS Belt: I've always found it difficult to get enough tension on the PS belt in that cramped space. Try this trick: From the front, wedge the wide flat part of a screwdriver or prybar into the slot of the front slot of the lower mounting bracket (red high-lighted area is shown on the rear bracket - my mistake but you get the idea). Apply leverage by pulling the handle towards the front of the car with the blade against a solid part of the PS pump body. This leverage forces the pump to move to the rear of car, creating tension on the belt. Hold tension, tighten the bolt and you're done. 3) Custom Built PS hose: Here's a tip that's not very hard to do and will save you $$ when repairing the Power Steering High Pressure Hose. I used a grinder and Dremel tool to remove the old crimps from my leaky OEM PS high pressure hose but retained the factory OEM fittings. Took me a little over an hour or so. Work carefully and try not to cut or grind into the original fittings. I nicked mine a few times but it was still OK. Took it to my friendly neighbourhood hydraulic hose shop. They crimped on new ferrules and a higher-than-spec, wire-reinforced hose for only $14, taxes in. Sure beats paying $80 for a jobber hose or $150+ for a weak, non-reinforced Toyota OEM hose. :wink: Here's how the fittings look disassembled below: The hose is double-wire braid reinforced, rated @ 4800 psi. Funny, the shop guy realized after he made it that it was a bit of over engineering, but it'll never leak again Previously, I've also used the single-wire hose that was rated @ 2600 psi - more than adequate and what I'd recommend because it has a bit more flex. End.
Re: PS Pump & Hose Links thanks for all this rick, im sure members will get some much needed help from it...
Re: PS Pump & Hose Links Wow Rick, thanks for those pictures. On the first picture where it shows to disconnect to hose with that SST, that is where mine's leaking. When I pulled my car out of the shop to take home over spring break there was a huge puddle of PS fluid so the teacher helped me find the leak and as I was turning the wheel lock to lock (engine running) bubbles where coming out of that crimp. If I paid you what it would cost to make that super strong hose would you get one made for me? I don't know of any shops around where I live that is why I ask. If you will that'll be awesoooome! :mrgreen: -Tanner
Thanks for the write up. There was a leak on the hose of my sisters 94 corolla and i saved a ton of money to getting a hydraulic place to fix it. they did brake lines there too, but anyways i just took the hose and all to them and they cut it, tinned on new threaded ends to the metal pieces(hopefully not to confusing). The advantage to this is that if the hose ever goes again it is just a new length of hose i need and threat it on. My question is i forget the ps fluid refilling procedure if someone can help me out. Knock to knock 7 times each for 2-3 seconds?
Interesting having them put on threaded ends to make essentially a removable rubber hose section. Clever!
Hell yeah, this is clever, mine needs doing and have a hydraulic joint down the road so will get them to do this mod.
I just went to two local shops and they both said they didn't have a ferrule that they could use to put the steel braided hose on our fittings and but they could use a regular hose Said hose is only good up to 300psi though. What does our system run at?
Not sure what our system runs at but a regular non-reinforced hose won't do it. I wouldn't recommend it because that's just asking for a leak later. The steel reinforced hoses I use are good to 2600 psi. Try searching under industrial hose shops. Do you guys have Lordco Auto where you are? They also do custom hoses. If you can't find anything, you can always just use the jobber hose, it's textile reinforced and costs about $40 last time I checked. Good luck!
Yeah, single braid reinforced as a minimum I think I still have a remanned spare here in NZ if anyone needs, is it the same on RHD cars? (looks like the same part) I took it out when I converted my hoses to the ST202 type a our JDM's don't have a cooler. http://www.st162.net/forum/showthre...ore-jdm-oddities&p=66147&viewfull=1#post66147 I have another issue lately - At full lock my pump or rack is squealing loudly, it's f/n embarrasing sometimes and there's no difference in feel. I have reconned a spare pump to put in but before I waste time I'd like to know if anyone has had this issue before
Yes, no bubbles or change in feel - just a god awful sound like a busted waterpump every time I try to manouver. Belt is new & tight too so I don't think slipping
