What It Is Used For

• Restoring oil flow through a damaged or leaking cooler hose assembly.
• Replacing rusted tubing that no longer holds pressure.
• Correcting fitment issues caused by bent or distorted original lines.
• Addressing oil seepage at hose connections or line sections.
• Replacing a worn oil cooler hose on a Ford Explorer or Mercury Mountaineer.

Installation Notes and Tips

Verify the inlet application and compare the original routing, end sizes, and overall length before installation. The pre-bent design is intended to match factory-style routing, which helps reduce line stress and alignment issues during replacement. Confirm that the 15 mm hose ends and 33.5-inch length match the removed part.

Quality Assurance

Sunsong oil cooling hoses are manufactured to meet or exceed original equipment performance standards. The steel tubing is zinc electroplated for added resistance to corrosion and rust, and the assembly is engineered to operate across a wide temperature range from -40 to 350 degrees Fahrenheit.
