Durable Construction and Precise Fit

This Dorman automatic transmission oil cooler hose assembly (part number 624-157) is constructed from high-quality rubber material that withstands extreme temperatures and pressures commonly found in transmission cooling systems. The natural hose color indicates the use of durable rubber designed to resist cracking and degradation over time. With a length of 60.5 inches, this hose assembly is tailored to fit specific vehicle models, ensuring proper routing and connection.

The hose ends are designed for secure attachment: one end features male threads for a tight seal with compatible fittings, while the other end uses a hose barb to maintain a firm grip on the transmission line. The hose is not flexible, which helps maintain consistent fluid flow and prevents kinking under operating conditions.
