Restore reliable cooling for your Dodge Durango or Jeep Grand Cherokee with the Dorman 603-002 Pressurized Coolant Reservoir with Cap. This direct replacement mirrors the size, shape, and function of the original tank, helping you maintain accurate coolant levels and steady system pressure during daily drives and longer trips alike.

Built to endure the demands of under-hood heat and engine vibration, the reservoir uses sturdy materials designed to resist deformation and leakage. The result is a component that stays resilient across temperature cycles and road chatter, contributing to more predictable cooling performance when you need it most.

Why this reservoir stands out

  • Direct replacement that matches the fit and function of the original for a straightforward swap.
  • Engineered for a seamless installation so you can complete the job with confidence.
  • Durable construction built to tolerate heat cycles and road vibration without deforming.
  • Backed by a long-standing automotive aftermarket heritage, reflecting a century of experience in the field.
  • Garage tool verification helps ensure you select the precise part for your exact make, model, and trim.

What you can expect in real-world use

In daily driving or on extended trips, a well-sealed reservoir helps keep coolant at the right level, supporting stable engine temperatures and reducing the chance of coolant-related spills. When you notice changes in cooling behavior or a slow leak, replacing the reservoir with a proven part is a practical step to restore peace of mind without guessing at fit.

This part is compatible with the following vehicles:

  • Dodge Durango: 2016–2021
  • Jeep Grand Cherokee: 2016–2021

To confirm fitment, enter your vehicle’s make, model, and trim level in the garage tool before purchasing. This helps ensure the 603-002 matches the exact dimensions and connection points your SUV expects, easing installation and reducing downtime.
