Product Details

The Dorman 603-139 Pressurized Coolant Reservoir is engineered to provide reliable coolant overflow storage and system pressure maintenance. This direct-fit replacement tank restores proper coolant system function in vehicles where the original reservoir has failed due to age, heat stress, or physical damage.

Key Features:

  • Durable high-impact plastic construction resists cracking and warping from extreme temperature cycling
  • Pressurized design maintains proper coolant system pressure for optimal engine cooling performance
  • Integrated level markings allow easy coolant level monitoring
  • Includes mounting points for secure installation using factory hardware
  • Direct replacement for worn or damaged original equipment reservoir

This coolant recovery tank is designed to withstand the harsh underhood environment, preventing coolant loss and ensuring consistent cooling system operation. The robust construction delivers long-term durability and helps maintain proper engine operating temperature.
