Product Details

The Dorman 603-507 is a non-pressurized engine coolant reservoir designed to provide reliable coolant overflow and recovery for your vehicle's cooling system. This replacement reservoir is manufactured from high-quality materials engineered to withstand the demanding conditions of underhood heat and constant engine vibration.

Key Features:

  • Direct replacement design matches the fit and function of the original equipment
  • Non-pressurized overflow reservoir with cap included
  • Durable plastic construction resists cracking and degradation from temperature extremes
  • Engineered for seamless installation with no modifications required
  • Backed by over 100 years of Dorman's automotive aftermarket expertise

This coolant reservoir serves as a critical component of your vehicle's cooling system, collecting excess coolant as it expands during engine operation and returning it to the radiator as temperatures drop. The transparent design allows for easy visual inspection of coolant levels without removing the cap. When your original reservoir becomes cracked, discolored, or begins to leak, the Dorman 603-507 provides a quality OE-style replacement solution that restores proper cooling system function and prevents coolant loss that could lead to engine overheating.
