International IH Cabover Radiator Tubes-Hoses

Frequently Asked Questions About International IH Cabover Radiator Tubes-Hoses

What do radiator tubes and hoses do on my International IH cabover?

These components carry coolant between the engine, radiator, and other cooling system parts. Radiator tubes are typically the rigid or semi-rigid metal sections, while hoses are the flexible connectors that link the tubes, radiator, and engine block together. Keeping these parts in good condition helps maintain proper coolant flow and prevents overheating.

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

Common signs include visible cracking, bulging, soft or spongy spots, coolant leaks or residue around fittings, and low coolant levels without an obvious external leak. If you notice overheating issues, a sweet smell near the engine, or coolant puddles under the truck, it is a good idea to inspect the tubes and hoses for wear or failure.

Will these tubes and hoses fit my specific IH cabover model and year?

Fitment can vary by model year and engine configuration within the International IH cabover lineup, so it is important to check the listed application details on each product page before ordering. If you are unsure about compatibility, having your VIN or engine model on hand when contacting our parts team can help confirm the correct part for your truck.

What material are the replacement hoses and tubes made from?

Hoses in this category are generally made from rubber compounds designed to handle engine heat and coolant exposure, while tubes may be metal or a combination of metal and rubber connections. Always check the specific product listing for material details, since construction can differ between OEM-style and aftermarket options.

Can I install a radiator tube or hose myself, or should I have a mechanic do it?

Many truck owners with basic mechanical experience are able to replace radiator hoses and tubes themselves, since the job typically involves draining coolant, removing clamps, and swapping the old part for the new one. However, if your cabover has limited engine access or you are not comfortable working with a pressurized cooling system, having a qualified mechanic handle the installation is a safer option.
