Replace Worn-Out Radiator Hoses & Tubes with Ease

Keep your Freightliner Cascadia 113/125 cool with durable radiator hoses and tubes that can handle extreme temperature changes. Whether it's a worn-out OEM part or a general upgrade to your cooling system, our vendors offer high-quality replacement parts to cover all of your needs. Choose from radiator hoses, silicone coolant lines, rubber elbows, clamps, and fittings. Made with tough materials like EPDM and silicone, these parts are built to last and prevent leaks. Plus, many are direct-fit replacements for easy installation. Everything you need for your Cascadia's cooling system is right here!

Frequently Asked Questions About Freightliner Cascadia 113/125 Radiator Tubes-Hoses

What do radiator tubes and hoses do on the Cascadia 113/125?

These components carry coolant between the radiator, engine, and other cooling system parts on your Freightliner Cascadia. They keep coolant flowing properly so the engine stays at a safe operating temperature. If a tube or hose fails, you can lose coolant quickly and risk engine overheating.

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

Common warning signs include visible cracks, soft or spongy spots, bulging, leaks or coolant residue around fittings, and low coolant levels that keep recurring. If you notice your temperature gauge running higher than normal or see coolant puddling under the truck, it is a good idea to inspect the tubes and hoses for wear.

Will these tubes and hoses fit both the 113 and 125 Cascadia models?

Products in this category are listed for the Cascadia 113 and 125, but exact fitment can still depend on your truck's model year, engine, and cooling system configuration. Always check the part number and confirm it matches your VIN or existing part before ordering to make sure it is the correct fit for your specific truck.

Are these OEM parts or aftermarket replacements?

This category includes a mix of OEM and aftermarket options, depending on the specific part. Each product listing will note the brand and whether it is an OEM Freightliner part or an aftermarket equivalent, so you can choose based on your budget and preference.

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

Many drivers and shop technicians replace radiator hoses and tubes themselves, since the job typically involves draining coolant, removing clamps, and swapping the old part for the new one. That said, proper coolant disposal, correct clamp torque, and a thorough check for leaks after installation are important steps. If you are not comfortable working around a pressurized cooling system, it is worth having a qualified technician handle the replacement.
