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. :thumbsup:

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)

      R34 Skyline Sunroof Won't Tilt/Vent

      By ShezzDogs · Posted

      Hi guys, just after some guidance with an R34 sunroof that has stopped working correctly. It still opens and closes perfectly fine, but it no longer tilts/vents up or down. As a result, the rear of the glass now sags a bit as it drops down slightly in order to retract into the roof, but now it can't pop upwards into a flush position. I’ve probed the pins on the back of the switch connector with a multimeter and it seems like both switches (for open/close and tilt/vent) still work correctly. Any ideas on what it could be, or where I should even start in terms of diagnosing? I'm sure someone's had this issue before but I haven't been able to find anything online relating to this specific issue, most of the issues are with the seals leaking or the motor failing entirely. Thanks in advance!

      Do you have some data like fuel pressure? It's really hard to say if you're still fighting a fuel system issue at this point. Could be something weird like the FPCM dipping out.

      Yeah in that case, pulling the dent out. Event a very slight dent can create a lot of work filler-wise and there is a strong chance the panel won't be the factory shape when you are done (as the dent will result in a new high point created somewhere, then everything is brought up to that new high point... but the panel shouldn't be that high if that makes sense).  So you've filled and primed the panel and it is flat, why would you go back and remove the primer and add more filler?

      Something else I have been faffing with while the car was off the road is making the AC work. Assuming the car isn't at a thermal limit the idea of having AC while waiting in line to go on track sounds delightful. I have actually been lugging around the weight of the entire system since 2018 when the RB25NEO went in without it working at all.  The main reason was in the first few events before I got around to re-gassing it the rubber hose that runs under the manifold had the factory heat wrap/sleeve fail resulting in this: ~2 years ago I purchased a complete used R32 AC line set but when I finally went to install it the line i needed was different where the expansion section is I found a local place that was able to replace the rubber section and re-crimp. They also added some modern heat sleeve to the hose Tight fit but fingers crossed this is the last physical piece of the puzzle needed

      the top black section is bonded to the silver section with some form of rubber. I assume to isolated NVH from the box
