Pump oil

[R31Nismoid]

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.

umm aparently ppl use the redline shockproof or whateva it is, the same they use in their gearboxes....

[KamikazeR33]

umm hang on.. maybe dats the diff.... my bad

[R31Nismoid]

so no-body has ever changed or looked at their HICAS oil ?!?!?

[NismoR34]

hopefully its not p*ss in there lol

sorry man had to say it. cant help cause I havent had to change mine yet - hoefully its not yellow though!

Call your mechanic!

[R31Nismoid]

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.

Go and ask your local nissan dealer.

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.

hhmmm... thanks guys!

never heard of green oil, oh well.

Went to a place last night and they do lots of imports. He said a full flush to clean out whatever oil i have not and then just P/S should be fine for HICAS!!!
