What is involved in the installation of the NISMO Power Steering Oil Cooler?

Have to remove bumper?

 

I just installed mine this weekend. Simple install, the hardest part is removing the bumper (which isn't that hard).

(1) remove front bumper
(2) disconnect existing PS cooler hoses/drain fluid
(3) disconnect PS cooler
(4) drill hole into plastic radiator holder
(5) install Nismo PS cooler
(6) attach hoses
(7) fill PS fluid/bleed lines by turing wheel

 

I second that--my bumper promptly fell on the floor when I released the last clip.

You may wish to pick up a few of the connectors that are visible when the hood is up...I broke some when I pulled them out. Also, some black zip ties (so they're not visible through the grill).

 

not sure about step (7), plz explain

 

Yes more details on #7 please. Where do you bleed it at?
Thanks!

 

Fill up the PS fluid ... turn the engine on, turn the steering wheel lock to lock a few times while somebody else tops off the fluid.

 

With the engine running and the power steering reservoir cap off, make 10 complete turns left and right this will bleed the system. This of course is after you have added any fluid that was lost during install.

 

what is the pro and cons if any of the NISMO Power Steering Oil Cooler?
sorry to steal your post. just wanted to know.

 

It avoids PS fluid overheat, boil, cavitation, whatnot under stress..

It's a good mod if you have larger than stock front tires and track the car.

 

Isnt the power steering fully loaded on when turning the steering is turning at standstill or extremely slow vehicle speeds. When vehicle is in motion, there is very little load on the PS. I dont really see how tracking would overheat the PS fluid.

Anyone care to explain? Sorry didnt mean to hijack, just continuing the discussion.

 

when tracking, u typically go in 30min sessions @ a time, which in that 30min, u are turning none stop and when you keep ur steering wheel pointed to one direction, the PS is actually fighting against natrual gravitational forces wanting to turn the tires another direction.

So those 2 combined at a continuous 30min interval can overheat the PS unit.

 

I did mine without removing the front bumper and it only took a few minutes. I just removed the under tray and went to work. I actuall installed a different one than the Nismo. I used one by Derale which is a few inches longer than the Nismo and cost $100 less.

 

Where did you get it from?
Thanks

Track definitely puts more stress on the unit(and PS unit does work hard on a course). Wider tires, R-comps, and modified suspensions also increase stress on it(couldn't quantify exactly, but from what I gather, it's significant)... overheating PS fluid at the track is not an unheard of occurance(maybe other factors playing in as well). Steering feel becomes "grainy" and inconsistent, and even a minor alteration is extremely annoying. 350z stock unit seems to work decently, but beyond a certain point it might become a good invesment (100$)

 

Also if you have a front mount then a large part of the airflow to even your stock cooler is blocked.

 

I just ordered one from Summit. Thanks again.

 

Generally, when a vehicle is driven to its limits, it is kept in the upper RPM ranges. It is the high speed of the power steering pump that creates the most heat, not the friction from the power rack & pinion.
