International ProStar Radiator Tubes-Hoses

Frequently Asked Questions About International ProStar Radiator Tubes-Hoses

What is the difference between a radiator tube and a radiator hose on the International ProStar?

Radiator tubes are typically the rigid or semi-rigid metal or molded plastic sections that route coolant between the radiator, engine, and other cooling system components, while hoses are the flexible rubber sections that connect those tubes and allow for engine movement and vibration. Both work together to keep coolant flowing properly, and both are prone to wear from heat, pressure, and age.

How do I know if my radiator tube or hose needs to be replaced?

Common signs include visible cracking, bulging, or soft spots in the rubber, coolant leaks or residue around fittings, a drop in coolant level without an obvious cause, or overheating issues. If you notice any of these symptoms, it is a good idea to inspect the full cooling system rather than replacing a single part, since related components often wear out around the same time.

Will these radiator tubes and hoses fit my specific ProStar model year?

International made changes to the ProStar cooling system design across different model years, so fitment can vary. Always check the part number and confirm it matches your truck's VIN or existing part before ordering. If you are unsure, our team can help verify fitment based on your truck's specifications.

Are these parts OEM or aftermarket, and does that affect quality?

We carry a mix of OEM and quality aftermarket options depending on the specific part. OEM parts are built to match the original factory specifications exactly, while aftermarket parts can offer a more budget-friendly alternative without necessarily sacrificing durability. The product listing will indicate which type you are purchasing so you can choose what fits your needs and budget.

What should I check before installing a new radiator hose or tube?

Before installation, make sure the engine is completely cool, drain the coolant system to avoid spills, and inspect the surrounding clamps, gaskets, and fittings for wear since these are often replaced at the same time. It is also a good practice to compare the new part side by side with the old one to confirm matching length, diameter, and fitting angles before bolting or clamping it into place.
