Power Steering/Hydro-Boost Flush

Today, I serviced the PS/HB system with a flush; I took some pictures and thought I’d share my procedure I do regularly to prolong the life of the PS and HB units and keep them functioning properly.

ITEMS NEEDED:

Drain pan
Large channel-lock pliers
5-6’ of 5/16” Fuel Line Hose
Scrap piece of 1x6
Small funnel
2-3 quarts p/s fluid, Just buy a Gallon Jug, it's cheaper.

I'm experimenting with synthetic Dex-VI, but plain PS fluid is fine. I pull heavy in bad traffic and experience higher heat levels than the average user. Looking for a synthetic PS fluid has proven to be an elusive endeavour.



Here we have the culprit at hand,



Compressing the spring clamp,



turn the hose left and right to break the seal, then pull back off the nipple.

CAUTION: in the picture below, you’ll see the curved metal brace coming from the cowl. I STRONGLY recommend you place a rag, towel, blanket, or some kind of cushion here.




When giving the final pull, the release/recoil will have the underside of your wrist striking this, with potential gashes and blood on your truck, resulting in you cussing me later. I pull mine regularly and it comes off much easier than one that's been on for 70-80k miles.

Using the spring clamp, I secure the drain hose at the HB unit




and lay the board to hold the hose in place with the drain pan in site from the Driver’s seat.



With the engine running and in Park, SLOWLY depress the brake pedal till it feels firm at the bottom and hold, turn the steering wheel from 12-3 o’clock and hold, release the pedal SLOWLY to the top, then bring the wheel back to 12 o’clock. Look down and you'll see the flow and then you can adjust your speed of press and release actions so as not to spray fluid out of the drain pan.

Here we see the old, burnt, and dirty fluid beginning to flow.





......................Continued on the next post, I'm too picture happy to conform here.
