well the time has come to top-up my HICAS oil as the pump's been making a bit of noise the past two days and is a bit low.

I opened the cap up and saw that the oil in there wasn't the pink i expected.

it was yellow.

Now, i thought that you can just use normal Power Steering fluid in there (which from my expiriances is pink) but this stuff being yellow has me thinking that there might be a different oil ?

And auto part places look at me weird when i say it's yellow.

Any pointers/advice on what to use ?!?!?!?

wanna do it soon before the pump blows up.

mechanic's i've spoken too (a fair few)

no idea they say. never seen yellow oil before is all i hear.

And the response is just put any old pink P/S oil in it...

But i'm reluctant to do it as i don't wanna if it's gotta be a specific type of oil as the HICAS is hydralic (sp) and stuff on a 31 (same as a 32).

Last thing i need is to try and find a 31 HICAS P/S pump. I know what my chances are of that.

From my experiance, Auto-tran fluid is pink, brake fluid is a tranparent/clear/yellow and P/S fluid is greenish... this prob won't be of any use to you, and prob complicate the situation futher!

I'd have to agree with DAHXX, ask a nissan dealer, or my a compliance/performance workshop???

sorry, no very useful... never had to do mine before either!

Does the R31 have a separate reservoir for the Hicas?

My R32 shares the reservoir, I know because when my steering fluid level got low my HICAS light flashed before anything else (I had a leak at the PS pump).

Any old power steering fluid should do it (or auto gearbox fluid if your in a pinch and cant get anything else, trust me it works). It's all hydraulic fluid after all. I wouldn't be too concerned.

Can't say I've ever looked at the colour of oils/fluids before though.

Dave, with that leak was it just the hose / loose hose? Or did you have to replace the pump? Mine is leaking a bit and I removed and checked the hose and it was fine :confused: Made sure the clamps are nice and tight now but havent tested it yet...will be testing [driving] it tomorrow.

Thanks.

    • No, code 21 is very straightforward. It can only be the things described in that diagnostic flow. In fact it has no way of knowing that the spark plug resistance is out of spec.
    • Hi, SteveL Thank you very much for your reply, you seem to be the only person on the net who has come up with a definitive answer for which I am grateful. The "Leak" was more by way of wet bubbles when the pedal was depressed hard by a buddy while trying to gey a decent pedal when bleeding the system having fitted the rebuilt BM50 back in the car, which now makes perfect sense. A bit of a shame having just rebuilt my BM50, I did not touch the proportioning valve side of things, the BM50 was leaking from the primary piston seal and fluid was running down the the Brake booster hence the need to rebuild, I had never noticed any fluid leaking from that hole previously it only started when I refitted it to the car. The brake lines in the photo are "Kunifer" which is a Copper/Nickel alloy brake pipe, but are only the ones I use to bench bleed Master cylinders, they are perfectly legal to use on vehicles here in the UK, however the lines on the car are PVF coated steel. Thanks again for clearing this up for me, a purchase of a new BMC appears to be on the cards, I have been looking at various options in case my BM50 was not repairable and have looked at the HFM BM57 which I understand is manufactured in Australia.  
    • Well the install is officially done. Filled with fluid and bled it today, but didn't get a chance to take it on a test drive. I'll throw some final pics of the lines and whatnot but you can definitely install a DMAX rack in an R33 with pretty minor mods. I think the only other thing I had to do that isn't documented here is grind a bit of the larger banjo fitting to get it to clear since the banjos are grouped much tighter on the DMAX rack. Also the dust boots from a R33 do not fit either fyi, so if you end up doing this install for whatever reason you'll need to grab those too. One caveat with buying the S15 dust boots however is that the clamps are too small to fit on the R33 inner tie rod since they're much thicker so keep the old clamps around. The boots also twist a bit when adjusting toe but it's not a big deal. No issues or leaks so far, steering feels good and it looks like there's a bit more lock now than I had before. Getting an alignment on Saturday so I'll see how it feels then but seems like it'll be good to go
