Detailed Product Overview

This Dorman transmission line is engineered for vehicles that route automatic transmission fluid through an external cooler. The 8.1-inch straight hose uses quick disconnect fittings at both ends and 0.31-inch inside diameter connections to maintain secure fluid flow. Dorman 624-640 is listed for 2010-2017 Jeep Compass and 2010-2017 Jeep Patriot models without Off Road Crawl Ratio Transmission, as well as 2010-2012 Dodge Caliber applications.

What It Helps Address

• Transmission fluid leaks at the cooler line connection
• Cracked, corroded, or damaged factory hose assemblies
• Restricted fluid transfer between the transmission and cooler
• Loose or worn quick disconnect fittings
• Service issues on inlet and outlet transmission cooler line locations

Installation Notes

Verify vehicle fitment by year, make, model, and transmission configuration before installation. This hose assembly uses quick disconnect ends and does not include a gasket or seal. Inspect the mating cooler and transmission ports for wear, contamination, or damage before connecting the new line. Confirm proper routing to avoid contact with hot or moving components.

Quality Assurance

Dorman manufactures this replacement transmission cooler hose assembly with metal and rubber materials selected for fluid handling and temperature resistance in automotive cooling circuits. The design follows OE-style connection points for the listed Jeep and Dodge applications.
