Freightliner FL70-FL80 Radiators

Frequently Asked Questions About Freightliner FL70-FL80 Radiators

Will this radiator fit my specific Freightliner FL70 or FL80 model year?

Freightliner FL70 and FL80 trucks were built over a wide range of years with different engine options, including Cummins and Caterpillar variants, so radiator core sizes and mounting points can vary. Always check the year, engine type, and cab configuration of your truck against the listed specifications or fitment guide before ordering. If you are unsure, our team can help confirm compatibility using your VIN or engine model.

Is this radiator new, used, or reconditioned, and how does that affect performance?

Radiators in this category are typically offered as new aftermarket units, though some listings may include quality used or reconditioned options. New units generally offer the longest service life and often carry a warranty, while used or reconditioned radiators can be a budget-friendly choice if properly inspected and tested. Product listings will note the condition so you can choose based on your budget and how long you plan to keep the truck in service.

What is the radiator core made of, and does it affect cooling performance?

Most FL70-FL80 radiators use either an aluminum core with plastic tanks or an all-aluminum construction, depending on the manufacturer. Aluminum cores are valued for good heat transfer and resistance to corrosion. The core material and row count listed in the product details will give you a sense of the cooling capacity, so match it to your truck's original specifications or your typical duty cycle.

Can I install this radiator myself, or should I have a professional do it?

Replacing a radiator on an FL70 or FL80 is a moderately involved job that typically requires draining the coolant system, disconnecting hoses and mounting brackets, and properly bleeding air from the system after installation. Many experienced DIY mechanics can handle this with basic tools, but if you are not comfortable working with cooling systems or your truck has tight engine bay clearances, having a qualified diesel technician install it will help avoid leaks or airlock issues.

Does this radiator come with a warranty, and what does it cover?

Warranty coverage varies by manufacturer and whether the radiator is new or reconditioned. Most new radiators include a manufacturer's warranty covering defects in materials or workmanship for a specified period. Check the specific product listing for warranty length and terms, and keep your proof of purchase in case you need to file a claim.
