Running Power Steering Cooler

[godzl1975]

Hi All

Did a search maybe not typed in the right things but am looking for the correct way of putting in a PS cooler, I dont have HICAS anymore and all the solonoids have been removed previously. The rear stage of the pump was blocked off with a machined out washer/piece and orig bolt bolted back up to block it off. Ive attached a diagram.

Can anyone tell me is that is the correct way to fitting the cooler as in connections to right places.

good question. I'm not 100% on if that is ok or not, but the easiest way is just to run it in series with the factory cooler. the factory cooler/dampener is up the front near the radiator. just unplug the hose going into one end of it, plug that to your new cooler then run a hose from the new cooler outlet to the old factory ones inlet. done.

well if your coming of the return side of the pump it's right...

That would be the hottest part by my guess....

anyone know if i can use hose n clamp? or do i need a one like OEM one cos of the pressure of the pump?

why are you doing this godzl1975?

Is your power steering fluid overheating?

^^ same thing i was wondering also.

I have never heard of it being a problem... and by adding a cooler all your doing is bringing another element/point of failure into what is already a perfect setup.

There is already a cooler for the PS system in the GT-R's. It is infront of the radiator, but behind the I/C on the drivers side of the bonnet latch. It is simplty a small diameter pipe with external fins.

Simply remove it & replace it with a proper sized cooler. A small 100mm by 250 ish size is more than adequate.

That is what I did & it stopped the P/S fluid from getting hot, expanding & then leaking out of the top of the reservoir.

And yes hoses & clamps work fine.

Thats exactly what I did, except the thing is that the cooler runs off the HICAS part of the system.

So yes thats how you connect the cooler, I used hose and clamps, no issues, trackdays completed with no overflow! (yes fluid is at spec'd level)
