Dorman 603-5103 front coolant recovery tank for the 2001-2013 International 5600i and other vehicles holds overflow coolant from the cooling system under pressure. This Dorman coolant recovery tank is entirely clear plastic, which does away with the leak-prone level indicator that fails on the original in certain International vehicles.
- Part of the Dorman HD Solutions line of heavy-duty replacements
- Clear plastic lets you read the fluid level without a separate level indicator
- Plastic body that resists cracking from extreme temperatures
- Pressurized, with a spring-loaded twist cap rated to 15 psi
