Freightliner FLC120 Radiator Tubes, Gaskets-Hoses

Frequently Asked Questions About Freightliner FLC120 Radiator Tubes, Gaskets-Hoses

What is included in this category?

This category covers the coolant-carrying components for the Freightliner FLC120 cooling system, including radiator tubes (also called radiator cores or tube assemblies), radiator gaskets, and coolant hoses. These parts work together to seal and route coolant between the radiator, engine, and related cooling system components.

How do I know if a radiator tube, gasket, or hose will fit my FLC120?

Fitment can vary based on the model year of your FLC120, the engine it is paired with, and the specific radiator or cooling system configuration originally installed. Always check the part number against your truck's existing component or consult with our parts team to confirm compatibility before ordering.

What are the signs that my radiator tube, gasket, or hose needs to be replaced?

Common warning signs include visible coolant leaks, coolant puddles under the truck, low coolant levels that require frequent topping off, overheating on the gauge, or a hose that feels soft, brittle, or cracked to the touch. Gaskets that have hardened or lost their seal can also cause seepage around fittings and connection points.

Are these parts new, used, or reconditioned?

We offer a mix of new aftermarket and quality-inspected used parts depending on the specific item and availability. Each product listing will specify the condition, so be sure to check the details on the individual part page before purchasing.

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

Many hoses and gaskets can be replaced by someone with basic mechanical experience and the right tools, especially if you are comfortable draining and refilling a cooling system safely. Radiator tube or core replacement is more involved and often requires removing the radiator assembly, so if you are not experienced with cooling system repairs, having a qualified diesel mechanic handle the installation is recommended to avoid leaks or damage.
