Product Details

The Dorman 603-5103 is a heavy-duty pressurized coolant reservoir designed as an OE FIX solution for select International commercial vehicles. This replacement reservoir addresses a common failure point found in the original equipment design.

Key Features:

  • Constructed entirely from clear plastic material for improved durability
  • Eliminates the original design's problematic level indicator that was prone to leaking
  • Engineered specifically for pressurized cooling systems on heavy-duty applications
  • Direct replacement for failed OEM coolant reservoirs
  • Clear construction allows for easy visual inspection of coolant level and condition

This OE FIX design improves upon the original equipment by removing the integrated level indicator component that commonly developed leaks, providing a more reliable long-term solution for maintaining proper coolant system function in International trucks.
