Frequently Asked Questions
What does the PSC HK2099 cooler kit do?
The HK2099 kit improves power steering fluid cooling and increases return-line flow, helping prevent fluid overheating and steering fade during heavy off-road use or hydraulic assist steering applications.
Why is steering fluid cooling important on Jeep JK models?
Large tires, off-road crawling, and hydraulic assist steering systems generate significant heat in the power steering system. A heat sink cooler reduces fluid temperature and helps extend the life of pumps, gearboxes, and seals.
Does this kit include everything needed for installation?
Yes. The PSC HK2099 kit includes the heat sink cooler, upgraded return hose, fittings, and installation hardware required to complete the upgrade.
Where should the heat sink cooler be mounted?
PSC recommends mounting the cooler below the power steering pump level and outside the engine compartment, commonly along the frame rail or under the radiator.
What steering fluid should be used with PSC steering systems?
PSC recommends using SWEPCO 715 power steering fluid to maintain optimal system performance and durability.
