This heat sink power steering cooler kit is built specifically for Jeep JL and JT models equipped with the 3.0L diesel engine and factory EHPS pump. Diesel applications generate steady heat, and this kit is designed to manage it without adding unnecessary complexity.

The single‑pass heat sink cooler sheds heat efficiently while keeping fluid movement stable. PSC hose assemblies are sized and routed for the diesel layout, and the JL/JT‑specific mounting bracket keeps everything secure and protected where it belongs.

This is a purpose‑built solution for diesel trucks that see real use and need their steering system to stay consistent mile after mile.
