Built For OE-Style Routing

This Dorman transmission cooler hose assembly is engineered from durable components to replace original cooler lines that have become cracked, corroded, or damaged. The molded assembly design helps maintain the original routing and connection points for the transmission oil cooler circuit on Jeep TJ and Jeep Wrangler models, while the 54-inch length and 0.296-inch inside diameter support proper fluid transfer at the inlet and outlet.

• Restricted fluid flow caused by a compromised hose assembly

Installation Notes

Verify vehicle application before installation. This assembly is listed for 2003-2006 Jeep TJ and 2003-2006 Jeep Wrangler at the inlet and outlet positions. Inspect the mating cooler ports, clamps, and sealing surfaces before assembly, and confirm the hose routing matches the original layout to avoid kinks or contact with hot or moving components.
