Detailed Description

Dorman 14152 transmission oil cooler line clip is designed for vehicles that use a quick-disconnect cooler line connection at the transmission or cooler circuit.

What It Helps Fix

• Corrosion-related clip failure at the quick-disconnect fitting
• Missing clip after transmission or cooler line repair
• Sealing issues caused by incomplete line retention

Installation Notes and Tips

Inspect the cooler line fitting and sealing surfaces before installation. Confirm the line diameter matches the clip range of 1/4 in to 5/16 in, and verify the application against the vehicle’s original retaining style. Install the clip fully into the quick-disconnect fitting so the line locks in place before returning the vehicle to service.
