Detailed Product Description

The Dorman 603-282 engine coolant reservoir is a replacement part tailored for Ford and Lincoln vehicles such as the Expedition, F-150, F-250, Mark LT, and Navigator. Made from sturdy plastic, this reservoir is designed to withstand the thermal and mechanical stresses of engine operation. Its irregular shape and specific dimensions (18.5 inches long by 14.5 inches high) allow it to fit precisely within the engine bay of compatible vehicles. The black and clear coloration provides a clear view of coolant levels, helping to prevent overheating issues. The included flip-top cap facilitates easy access for coolant refills and maintenance. Although the reservoir is non-pressurized, it integrates seamlessly with the vehicle’s cooling system to maintain proper fluid levels and prevent leaks. The single mounting hole and included mounting bracket ensure a secure fit during installation.

  • Restores proper coolant containment for Mark LT vehicles experiencing coolant loss
  • Eliminates coolant contamination due to damaged or missing reservoir caps

Installation Notes and Tips

  • Ensure the engine is cool before removing the old reservoir to avoid burns
  • Verify the mounting bracket and hole align correctly with the vehicle’s frame
  • Check that the flip-top cap seals properly to prevent coolant leaks
  • Use appropriate tools to avoid damaging the plastic reservoir during installation
