    Hey fellas, I have a 93' ECRB 2WD 5.7L auto trans
    and I am wanting to install a P/S cooler and in line filter.

    My question is which hose is the low pressure line?
    If i'm not mistaken, the hose that is crimped on both ends is the high pressure side
    and the one with the hose clamp is the low line, is that wrong?

    Also, which line would I put the filter on and which way do the hoses flow?

    Thanks

    You are right, the hose with the crimped on connectors will be the high press hose. The fluid flows from the pump through the high press hose to the steering gearbox and then returns to the resevoir through the low press return hose.
    As for cooler and filter I`ve never fitted either, however the fluid press. from the pump in the high press. line could be around 1000-1500psi so I would think you would need to fit both in the return line.
    Just my opinion.

    ECRB? WTF? Before you spend money, what are you trying to accomplish by installing a power steering cooler? Case is correct about the routing. You don't want to blow up your filter. If you're just trying to keep the fluid clean by changing the filter, just use a suction gun and top it off. Much cheaper. I just can't imagine what you're doing to a Chevy truck to make the fluid so hot it needs a cooler. Would love to help you if I can. I just don't understand.

    Thanks Case and I was gonna hook it into the low side line but wanted to make sure I knew which hose was which.

    Roadblock, it's stupid hot and humid here and before the cooler weather moved in, my fluid started forcing itself out via reservoir cap while idling. I know that don't sound like a heat issue but it's my guess. The cooler is only $20 and I already have it so it's goin in. Filter was like $6. I just put in a new pump so I wanna maximize longevity. And also, you said "by changing the filter" - there is no filter; the one I have is an inline filter.

    I see. I may be wrong, but it doesn't sound like a heat issue. Houston gets over 100 degrees for a few months at a time every year, never had that problem. Not even while towing a trailer. I'm thinking more along the lines of a restriction somewhere. I hope it works for you. Let us know.

    Yea thanks and I actually can't remember if the fluid spewed out before or after I replaced the pump but I just want the new one to last. I think the restriction may have been in the gearbox; did lots and lots of muddin in the past and had it submerged well above the gearbox a few time so I should probably flush it with seafoam.

    Also, for the fluid, it's fresh hence a new pump so if anything it's probably in the gearbox like I said.

    believe it or not, but your truck already has a factory "cooler" in the frame horn. atleast my 97 does.......

    you can see the line entering the frame horn in this pic from when i did my front mount hitch. it's just a length of bent tubing to allow the fluid to cool before going back to the resevoir.
