Product Details

The Dorman 603-955 is a direct-replacement non-pressurized coolant reservoir designed to restore proper cooling system function on your vehicle. This recovery tank holds excess coolant that expands when the engine heats up, then draws it back into the radiator as the engine cools down, maintaining optimal coolant levels.

Key Features:

  • Non-pressurized design for overflow/recovery applications
  • Durable plastic construction resists corrosion and thermal stress
  • Direct-fit replacement for worn or damaged original reservoir
  • Includes mounting provisions for secure installation
  • Translucent design allows easy coolant level monitoring
  • Engineered to meet or exceed OEM specifications

Dorman is a trusted name in automotive replacement parts, offering reliable solutions for cooling system maintenance and repair. This reservoir helps prevent coolant loss and ensures your engine maintains proper operating temperature.

The only issue is my concern that the make of vehicle was never confirmed. this I would like to do.

Just ordered. Good pricing; then checked out reputation on Reseller Ratings - seems solid; then ordered.

Color of the handle wasn't clear.

Fine. Cheaper than amazon.

The price for this part was more affordable than the auto parts store and I look forward to doing business with you again.

Good

The reviews for the product didn't belong to it. Just so you are aware of it

cheapest prices

So far so good
