Steering Cooler for Power-Steering Systems

This Dorman 918-323 steering cooler is a transparent replacement component designed for automotive power-steering circuits. It fits vehicles requiring an external heat exchanger to lower fluid temperature. The cooler suits DIY mechanics and professional technicians performing cooling-system maintenance or repairs. It is not for buyers who need an integrated reservoir or a cooler with pre-formed hose ends.

Upgrade from Damaged or Missing Factory Coolers

The unit replaces a leaking, clogged or absent original-equipment cooler that allows fluid to overheat. The jump is worth it when steering whine, stiff operation or boiled fluid appears after sustained driving or towing. It is not for installations that demand a specific mounting bracket or a cooler with an internal bypass valve not described here.

Check Hose Diameter and Routing Space Before

Verify that your power-steering hose inner diameter matches the cooler inlet and outlet dimensions before purchase. Confirm the vehicle has sufficient clear space along the return line for a straight-through transparent body. Ensure the existing clamps or fittings are reusable or budget for new ones. Do not order if the factory plumbing uses proprietary quick-connect ends incompatible with barbed fittings.

Questions about this item

What hose diameter does the Dorman 918-323 steering cooler accept?

The cooler uses standard hose barbs that fit common power-steering return lines; match the inner diameter of your existing hose when installing.

How do you install the Dorman 918-323 steering cooler and what step is often missed?

Mount the unit in the return line using hose clamps, then bleed the system fully; skipping the bleed leaves air in the rack and causes noise.

When should the Dorman 918-323 steering cooler be replaced?

Replace it if the transparent body cracks, turns opaque, or leaks at the barbs, or whenever the power-steering fluid is flushed.
