HOW TO DO AN ADVANCED SEARCH.

Mon Jul 08, 2013 3:56 pm by Admin


For the benefit of 944Hybrids users there are two search functions available for you to use.
The purpose of this sticky is to explain the "Advanced Search" function because it is much more powerful and is the best choice when researching information.

When you log on to the site a list of options is shown in a line at the top of the page. One option is labelled "Search", use this option (NOT the search box lower down on the right).

After you click on the upper search option, a drop down box appears. At the bottom of this box is a radio button marked "Advanced …

Power Steering HP Line

Post  acorad on Tue May 26, 2015 5:27 pm

Hi all, it's been a while since I've posted.

The car's just been humming along, as it should!

Anyway, over the weekend I developed a leak in my power steering high pressure line. Lots of fluid dripping cooking on my catalytic converter!

The line is routed from the PS pump, down and under the PS pump, then pinched between the exhaust headers and inner fender walls, and then down to the steering rack.

It is a tight squeeze between the headers and fender walls, so the PO/builder wrapped the rubber line with foil header wrap and it looks like it's leaking from under the foil wrap.

Is there a better way to route that line? Is there a stronger line?

Seems like an easy fix if I had to do it again (one wrench, remove old line, replace with new, add PS fluid) but I'd like to make a more permanent repair.

Thanks!

Andy

Is there a different way to route the PS HP line?

Maybe cut a couple holes in the inner fender wall and route the line out through the inner fender wall and then back in again before going down to the rack, such that the line is routed on the far side of the inner fender wall instead of being pinched between it and the headers?

Mine goes straight down from the ps pump between the alternator and water pump. There the braided line connects to the factory steel line, cut with an AN fitting brazed on.

Thanks Rich! I wonder if my line would have been the right length to go under, instead of around...

Maybe so. The trick in going under is squeezing past the head of the rack. By using the stock steel line, it gets between the rack and the engine block. The braided steel line I made couldn't fit through there. But if longer, it might could fit between the rack and the engine mount on the outside. That's where my return line comes forward up to the cooler at the bumper.

Hi all, checking to make sure ATF Dextron II D is what we use in our power steering?

That's what I've been reading is the correct fluid for the rack.

If so, anyone know where to get it?

Andy

PS: Ha, just stopped at a 7-11 and happened to see that their house brand ATF says "for use where Dexron II, Dexron III, or Mercon fluids are specified."

I guess this is the right stuff?

dexron 2 d spec was replaced with dex 3, and later dex 3 h spec. all are compatable. dont use dex 6, its far thinner and is quite different. there now is "universal atf" or d3m fluids, they are the same as dex 3 h spec.

My first try I used Valvoline synthetic "Power Steering Fluid" with my 20 year old rack which had been sitting out of the car, dry for 2 years. It sprung leaks at both ends after 3 track days.

My second try I've used Valvoline non-synthetic "DEX/MERC" automatic trans fluid. This with a freshly rebuild rack. 2 track days and no leaks so far.

YMMV

Q: Are there supposed to be any washers or anything at the banjo bolt?

Which banjo? The hard lines from one point to another on the rack have o-rings and no washers. The supply and return lines have copper crush washers on each side of the banjo, 2 per joint.

Thanks Rich, it's the banjo on the line I'm replacing, the high pressure line from the reservoir to the rack.

The washers are MIA.

Any idea where I can get those crush washers and what size they are?

I think when I described the line to you I mentioned you would need new washers. they are crush washers and leak if re used.

Thanks Eric, I think you did too. I just didn't know what you were talking about as I'd never taken one of these apart before. :-)

Surprisingly I ended up not using the metal line to the steering rack that you sent me because I couldn't get it to snake past the rack. I did use the flexible line and the metal line to the PS pump that you sent me.

No worries at all though, as the metal line to the rack that was already on my car, and was connected to the leaking power steering line that was routed out between the headers and the fender wall, worked just fine.

I just flipped it around and it easily snaked past the rack and attached to the flexible power steering line that you sent me.

Makes me wonder if the guy who built the car didn't know that that he installed that metal line backwards, and that's why he ended up routing the flex line around the headers so as to connect with the backwards metal line.

Anyway, all is good now, I just need to add the crush washers.
