Z1's Power Steering Cooler Upgrade Kit for the Nissan 350Z and Infiniti G35 Coupe improves the cooling efficiency of the power steering system, increasing component life and providing more consistent performance when you need it most.

WHY DO I NEED A POWER STEERING COOLER?

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.

From the factory, your Z or G is equipped with a tube and fin-style power steering cooler. This cooler works well in light-duty street applications, however, in demanding applications such as drift cars 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 boils. 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.

Z1's Power Steering Cooler replaces the small factory cooler with a higher-performing ProCooler+ oil cooler core, much like the one used in our Engine Oil Cooler Kit. Its robust construction incorporates a high-density tube and fin core, crafted using industry-leading brazing technology to ensure exceptional durability and efficiency, and offers exceptional cooling capacity. Whether you're an occasional touge warrior or a dedicated time attack champion, our power steering cooler upgrade is up to the task!

INSTALLATION NOTE

By removing the factory power steering cooler, you will need to replace whatever fluid is lost. In addition, the increased volume of the larger power steering cooler will require additional fluid as well.  Z1 recommends using of either the Factory Nissan or Redline Power Steering Fluid, available separately.
