Power steering flow

[rt_hawk]

Does anyone know which way the power steering fluid flows into the PS cooler? Does it come in through the bottom nipple of the cooler and return to the PS resevoir from the top line coming from the cooler? I want to add a magnefine filter and I want to be sure on flow direction....

Thanks in advance!!

Here is what I did...pretty simple...flow is going up to the cooler from the line the filter is in and then over to the reservoir through the top line coming out of the cooler...

This is something that I really want to do for my 6.4. How is everything running with your install? Have you had an opportunity to open a filter up and see what it has caught?

Is there a better place to install?

Sorry for all the Q's.

I am also hunting for a at home p/s flush procedure for the power steering and even the transmission. I'll like to get everything clean before I do mine. The transmission will be a DieselSite though.

That's the best place I could find..if you find a better spot please let us know..

I used a mighty-vac and a hose splice barb to suck the old fluid out in the place where I cut the line for the filter...I capped one end and connected the pump to the other...worked really slick. Then refilled with Mobil 1 syn ATF. Had my wife start rhe truck and turn the wheel back and forth to get fluid back in the system and the air out as quickly as possible...Steering and brakes are quieter and stronger. I hope the filter keeps it that way.

Haven't cut it open yet since its only been around 4k miles...I also switched the clamps to corbin style spring hose clamps..I used 5/8" (16mm) clamps for the 3/8" ID hose...

Good luck! Here is a pic with the new clamps...

Very good and thanks for the info.

I'm suprised that a mod like this isn't getting so much traction with other members.

Not a problem and thanks, I know this is a fairly common mod for 7.3 and 6.0 guys it seems from when I was searching for info on this...that's how I found my hydroboost diagram to know which direction the flow went (magnefine filter is a directional one). The write up I found was for a 7.3 I think...Here are the links...

Power Steering Flush for 7.3

The 6.4 hydroboost is pretty much the same deal as the 7.3, cooler is higher up and the hoses are different lengths and in different spots, but it's the same system in either truck...just make sure you DON'T put the filter in a high pressure line...they are the ones with crimped hydraulic style hose ends...

Have fun!

I think the hydro boost return to pump reservoir
is the easiest IMHO and mine is serviceable so I like the fact it's above the
fluid level in the reservoir

Where are you guys getting this filter? Thanks!

[rt_hawk]

I got mine at napa...it's a 3/8" magnefine filter...

got Mine at O'rileys it's even listed in their data base Magnapure 3/8's it is cleanable
