Z1 370Z / G37 Power Steering Cooler Upgrade Kit

starstarstarstarstar_half 4.9/5 - (12 Reviews)
Fits models: 370Z / G37...

Product Description

Z1 Motorsports 370Z/G37 Power Steering Cooler Upgrade Kit for all '08+ Infiniti G37 and '09+ Nissan 370Z models.

Located just in front of the Radiator assembly, the Power Steering Cooler helps keep the power steering fluid's temperature under control. Like any other lubricant on a vehicle, the Power Steering Fluid serves two vital purposes.

  1. Lubricate the steering components and bearings.
  2. COOL THE VARIOUS COMPONENTS...including the bearings and seals in the pump and power steering rack.

Your Z or G is equipped with a factory tube and fin style power steering cooler. This cooler works well in light duty street applications however in demanding applications such as forced induction equipped vehicles and those engaging in track events the factory cooler isn't quite large enough to manage the extra heat. When pushed hard the power steering fluid can reach a critical temperature where the fluid will boil. Power steering fluid that has reached its boiling point will lose much of its lubrication and cooling ability, leading to accelerated wear of the power steering pump and rack & pinion. Once the fluid has reached the point of boiling, the fluid must be flushed and changed.

The Z1 Motorsports Power Steering Cooler replaces the small factory cooler with a higher performing Setrab oil cooler core, much like the one used in our Engine Oil Cooler Kit. In addition to the increased cooling performance, the Setrab core has proven itself as one of the most durable oil coolers available.  Whether you're an occasional touge warrior or a dedicated time attack champion, our power steering cooler upgrade is up to the task!

The Z1 Motorsports 370Z/G37 Power Steering Cooler comes complete with the following hardware:

  • Setrab 1 Series Oil Cooler Core (13 row) (x1)
  • M22 x -6 AN Fittings (For Cooler) (x2)
  • -6 AN 90 Degree Socket-Less Fittings (x2)
  • Z1 3/8" Reinforced Power Steering Hose Kit (x1)
  • Z1 Custom Oil Cooler Bracket w/ Hardware (x1)
  • Z1 Motorsports Power Steering Cooler Installation Manual

Building upon the superior, Setrab Oil Cooler's design, the Z1 Motorsports Power Steering Cooler features a 100% bolt-on installation requiring no modification, drilling or cutting of the vehicle to perform the installation.  The Z1 Motorsports Power Steering Cooler's installation kit allows for a low-profile install, allowing for adequate room for intercoolers, etc.

Please note: 
By removing the factory power steering cooler, you will need to replace whatever fluid is lost. In addition, the increased volume of the Setrab Power Steering Cooler will require additional fluid as well.  Z1 Motorsports recommends using of either the Factory Nissan or Redline Power Steering fluid, available separately. You may find power steering fluid for your 370Z/G37 HERE.

Questions our customers have asked

Hi, does this Z1 370Z Power Steering Cooler upgrade kit fits on a 2015+ Nismo (due to the damper) ?
We have not had clearance issues with it but if needed the damper can be shimmed forward slightly. We have done this for years when needed even on the V1 Nismos.

The kit was very impressive! Every part fit perfect and made it very easy to install. Solved my issue I was having ps issues getting hot after a few laps. No issues on a 90 degree day after this!!

This is a bit product is a bit misleading because it is a perfect fit on the 350z. I saw a few videos on YouTube that others had posted and decided for the price it was well worth the try. I got it installed yesterday and it seems to be doing great, the install was super easy. While mounting it aligned well with the stock holes on the car and we ran an extra self tapper just to be extra secure. I was going to the Mishimoto cooler as a power steering cooler but the cost was so high and it was over kill even for drifting. Switched to Red Line D4 ATF fluid while I was at it and the steering never felt so good.

I had to change the some hoses and decided to upgrade the power steering cooler, installation was easy, 3 months later no leaks, steering feels great very worth purchasing.

Installs easily. Nismo braces have not much clearance so some small washers on the braces were recommended by Z1 and appear to work well.

Great mod overall and even better if you plan on servicing your power steering fluid. This new cooler paired with new fluid makes a better feel of the vehicle. It also puts less stress on the pump keeping your power steering fluid temp lower. If you wanna go Z1 all out Z1 offers there power steering hose kit. @vq.herc
