Freightliner Cabover Radiators

Frequently Asked Questions About Freightliner Cabover Radiators

Will this radiator fit my specific Freightliner cabover model?

Freightliner cabover models such as the FLA, FLB, FLC, and FLD were produced over many years with different engine options, and radiator core sizes, tank configurations, and mounting points can vary between them. Always check the year, model, and engine listed in the product details against your truck's specifications before ordering, and reach out to our team with your VIN or truck details if you are unsure.

Is this a new, used, or remanufactured radiator?

We carry a mix of new aftermarket, used take-off, and remanufactured radiators depending on availability. Each listing specifies the condition, so be sure to review that information carefully. Used radiators are inspected before sale, but if you need a warranty or long-term reliability, a new or remanufactured unit is generally the safer choice.

What material is the radiator core and tanks made of, and does it matter?

Most heavy-duty radiators use an aluminum core paired with either aluminum or plastic tanks, though some older Freightliner cabovers used copper-brass construction. Aluminum radiators tend to be lighter and resist corrosion well, while copper-brass units can be easier to repair. The product listing will note the core and tank material so you can match it to your cooling system needs.

How do I know if my radiator needs to be replaced versus repaired?

Common signs that point to replacement rather than repair include a cracked or leaking core, damaged tanks that can't hold pressure, bent or crushed fins reducing airflow, or persistent overheating even after flushing the system. If the damage is limited to a hose connection, cap, or minor leak, a repair may be more cost-effective, but widespread core damage usually calls for a full replacement.

What should I check before installing a replacement radiator?

Before installation, inspect the mounting brackets, hoses, cap, and fan shroud from your old radiator to see if they can be reused or need replacing as well. Make sure the new radiator's inlet and outlet locations match your truck's plumbing, and always flush the cooling system and refill with the correct coolant type after installation to avoid air pockets or contamination.
