Dorman 724-628 Automatic Transmission Oil Cooler Hose Assembly - Inlet and Outlet
Transmission Cooler Line for Wrangler JK
Dorman 724-628 is an automatic transmission oil cooler hose assembly built to match the original line routing and connection style for the 2018 Jeep Wrangler JK. It transfers transmission fluid through the cooler circuit without a bypass valve, helping eliminate the temperature-control issue associated with a stuck thermostatic valve.
For Jeep Wrangler JK owners searching for a direct-fit transmission cooler line, Dorman 724-628 provides a molded assembly with quick disconnect ends and OE-style dimensions for the inlet and outlet connection points.
Key Features
- Fits 2018 Jeep Wrangler JK, inlet and outlet
- Automatic transmission oil cooler hose assembly
- OE-style molded assembly with quick disconnect ends
- 36-inch length with 0.375-inch inside diameter at both ends
- Black and silver hose and housing finish
- Flexible construction with spring support
- Maximum working pressure: 250
- Operating temperature range: -40°F to 329°F
- Fittings included; gasket or seal not included
Detailed Description
This Dorman transmission cooler hose assembly is engineered for the 2018 Jeep Wrangler JK and matches the fit of the original equipment cooler line. It is designed for vehicles that use a transmission cooler bypass module, but this replacement line does not include the bypass valve, helping remove the risk of elevated transmission fluid temperatures caused by a valve that can stick. Dorman 724-628 is a practical OE-style replacement for Wrangler JK transmission cooler line service where the inlet and outlet cooler line needs to be restored.
This part cross-references Jeep OE part numbers 55111450AB and 55111450AC for the same application.
What It Helps Solve
- Transmission fluid overheating caused by a stuck bypass valve
- Leaking or damaged transmission cooler hose assembly
- Restricted fluid transfer through the cooler circuit
- Fitment issues from worn quick disconnect connections
- Service replacement for a failed Wrangler JK cooler line
Installation Notes and Tips
Verify the vehicle is a 2018 Jeep Wrangler JK with inlet and outlet cooler line routing before installation. Confirm the quick disconnect ends and line length match the original layout, and inspect mating surfaces for wear or contamination before connecting the new assembly. Because a gasket or seal is not included, reuse or replacement of related sealing components should be confirmed separately as needed.
Quality Assurance
Dorman 724-628 is built to match OE fit and fluid-transfer function for the specified Wrangler JK application. It is designed for transmission cooler service where bypass-valve deletion is required, helping maintain proper cooler line operation without the original thermostatic valve.
