Frequently Asked Questions About International WorkStar Series Coolant Reservoirs
What does a coolant reservoir do and why does it matter for my WorkStar?
The coolant reservoir, also called an overflow or degas bottle, holds excess coolant as it expands and contracts with engine temperature changes and helps remove air from the cooling system. A cracked, leaking, or improperly sealed reservoir can lead to low coolant levels, air pockets in the system, and eventually overheating, so keeping it in good condition is important for reliable operation.
How do I know if my coolant reservoir needs to be replaced?
Common signs include visible cracks or stress marks in the plastic, coolant residue or puddles around the tank, a cap that no longer holds pressure properly, or a coolant level that keeps dropping without an obvious external leak elsewhere in the system. Discolored or cloudy plastic can also indicate the material has degraded from heat exposure over time.
Will a replacement reservoir fit my specific WorkStar model without modification?
Coolant reservoirs can vary by model year, engine, and cab configuration, so it is important to check that the part you are ordering matches your trucks specifications before purchasing. If you are unsure, having your VIN or the OEM part number from your existing reservoir on hand will help confirm a correct fit.
Are these reservoirs made from the same material as the original equipment?
Most replacement coolant reservoirs are manufactured from durable, heat and chemical resistant plastic similar to what International uses on factory units, since the tank needs to withstand hot coolant and engine bay temperatures over the life of the truck. Always check the product listing for specific material details if this is a concern for your application.
What should I check when installing a new coolant reservoir?
Before installing, inspect the mounting brackets, hose fittings, and cap for wear, since these components often get reused with the new tank. Make sure all hose connections are seated securely and clamped properly, and after installation, refill the cooling system, check for leaks, and monitor coolant levels over the next several drive cycles to confirm everything is sealed correctly.
