Thread: RR PS Pump Limits Reached (Update: Hose Ripped)

Too much ps fluid maybe?

What ATF fluid is best to use?

Just put a larger pulley on you pump

my p11 never rev'd over 6200 rpm and my PS high pressure hose is leaking. 114k miles. that tells you something...

Yeah not that I see the actual issue it doesn't seem like revving that high was 100% at fault. Yesterday it happened after I accelerated a few times on the highway, PS pump started whining like it was dying (duh low fluid). This morning during daylight I could see the real issue.




Very tempted to do so, UR stopped making them


Now I'm wanting to do a SS braided line, there are some for S13/S14's, the only problem is getting them to work with our Banjo's and the PS pressure sensor.

regular power steering fluid will eventually kill our pumps, how long will it take? i have no idea.. i've been running it for like 3 years.. but all the while its been whining.. my friends whined a little at first but then i suggested swapping in some ATF an the whine is completely gone!

Also i've noticed that regular power steering fluid causes leaks!!

Delete PS = problem solved.

Na, in all seriousness, you have a good thought. Not sure if its true but could be. At least its a quick fix.

I would remove the PS if I didn't use it as a daily... Now the main problem is the sensor connected to the power hose. Need to find a way around it.

Thats for your idle up during turning, it triggers the fast idle control valve. Its not absolutely necessary just keeps the engine from bogging a bit when stopped and trying to turn the wheel at idle.

I've used Valvoline Synthetic P/S fluid (says design for Hondas on the bottle?) which is a clear fluid for as long as I can remember. I've never had any issues with this fluid.

There is a pressure regulation system built into the P/S pump. It uses a by-pass valve to control pressure in the system. If this by-pass system got overwhelmed you could have experienced higher than normal pressure in the system which led to the failure. That's a lot of revs. Bigger pulley sounds like a good idea regardless. I think there are OEM solutions that are bigger.
