Detailed Description

This washer fluid reservoir is designed for select Chevrolet, GMC, and Cadillac trucks and SUVs, including Chevrolet Tahoe, Chevrolet Suburban 1500, GMC Yukon, and Cadillac Escalade applications. Dorman 603-025 follows the original reservoir layout so the fill neck, cap, level indicator, and mounting points align with the vehicle’s washer system. This part cross-references GM OE numbers 22143999 and 25731418 for the same application.

Use this reservoir when the original tank is damaged, discolored, or no longer holds washer fluid. The clear plastic body makes fluid level checks straightforward, while the OE-style shape supports proper placement in the engine compartment on compatible GM truck and SUV platforms.

Common Repair Reasons

  • Cracked washer reservoir causing fluid loss
  • Broken or missing fill neck components
  • Leaking cap or damaged reservoir seal area
  • Low washer fluid warnings from a compromised tank
  • Poor windshield washer performance from an empty or damaged reservoir

Installation Notes and Tips

Verify vehicle year, make, model, and rear wiper configuration before installation. Transfer any required washer system components from the original assembly if needed, and inspect grommets, hoses, and the mounting area for wear before securing the new reservoir. Confirm the fill neck and cap are seated correctly to help prevent leaks.

Quality Assurance

Dorman designs this reservoir to match OE fit and function and to withstand underhood heat and engine vibration in specified applications. Part number 603-025 is built as a direct replacement for select GM vehicles, including Chevrolet Tahoe, GMC Yukon, and Cadillac Escalade models listed above.
