• Resolves coolant leaks from cracked plastic tanks or corroded aluminum cores
• Improves engine oil cooling through the integrated oil cooler
• Supports restoration of proper coolant flow with OEM style quick-connect fittings

Installation Notes and Tips

Ensure compatibility with your specific Ford or Lincoln model before installation. The radiator’s cross flow design requires proper orientation for inlet and outlet connections—verify the right side inlet and left side outlet placement. Use appropriate coolant and follow manufacturer torque specifications for hose clamps and mounting hardware. The absence of a radiator cap means the existing cap from the vehicle should be reused. Inspect hoses and clamps for wear during installation to maintain system integrity.
