Dorman 603-5124 Engine Coolant Reservoir
Engine Coolant Reservoir Replacement
Dorman 603-5124 is a replacement engine coolant reservoir built from plastic to handle underhood heat and engine vibration. It is engineered to match the original part’s fit and function for service on compatible vehicles, including make/model applications such as Ford and International platforms where this reservoir style is used.
Key Features
- Plastic construction for coolant system service
- Natural color reservoir body
- Irregular shape with 8 mounting holes
- Mounting brackets included
- Pressurized coolant cap included
- Cap maximum pressure rating: 15
- Maximum capacity: 10.2 L; working capacity: 8.8 L
- No level sensor included
- Dorman part number 603-5124
Detailed Description
This Dorman coolant reservoir is made to replace a damaged or leaking expansion tank in the engine cooling system. The reservoir is designed from quality materials to withstand heat cycling and vibration, and its form is engineered to align with the original mounting and hose connection layout. For buyers searching for an engine coolant reservoir for Ford or International truck applications, Dorman 603-5124 provides an OE-style replacement solution with the cap included and pressurized cooling system compatibility.
This part cross-references Monroe Shocks & Struts (e.g., 502.927, 575.10317) for the same application.
Common Problems It Can Help Solve
- Coolant loss from a cracked or aging reservoir
- Visible leaks around the tank body or seams
- Pressure loss caused by a worn reservoir cap
- Cooling system service issues after plastic tank deterioration
- Fitment problems when replacing a damaged OE coolant bottle
Installation Notes and Tips
Verify the reservoir shape, mounting hole count, and pressurized cap specification before installation. Transfer any reusable hoses or fittings from the original setup as needed, and inspect the surrounding cooling system for cracks, hardened hoses, or contamination before refilling. Confirm the vehicle’s cooling system is properly bled after installation to reduce trapped air.
Compatible With select Ford and International applications that use this reservoir design. Fits vehicle-specific cooling system layouts rather than universal applications. Dorman 603-5124 should be matched to the original reservoir configuration before purchase.
Quality Assurance
Dorman manufactures this replacement coolant reservoir to match original fit and function using materials selected for underhood durability. The part is built for direct replacement service in the cooling system and includes the pressurized cap specified in the product data.
