Kenworth T680 Radiators

Frequently Asked Questions About Kenworth T680 Radiators

Will this radiator fit my Kenworth T680 without modification?

Radiators are model and year specific due to differences in mounting points, core size, and engine cooling requirements. Always confirm your truck's model year and engine configuration against the fitment details listed on the product page before ordering to ensure a proper, direct-fit installation.

What material is the radiator core and end tanks made of?

Most replacement radiators for the T680 feature an aluminum core for efficient heat transfer, paired with either aluminum or durable plastic end tanks depending on the specific part and manufacturer. Product listings will specify the exact construction so you know what you're getting.

Is this a direct OEM replacement or an aftermarket part?

We carry both OEM and quality aftermarket radiator options. Each listing notes whether the part is OEM or aftermarket, along with the brand, so you can choose based on your budget and preference for original equipment matching.

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

Radiator replacement involves draining coolant, disconnecting hoses, and often removing surrounding components like the fan shroud or grille. While experienced DIYers with the right tools can complete the job, many customers prefer having a qualified diesel technician handle installation to ensure proper sealing and coolant system bleeding.

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

Common signs a replacement is needed include visible leaks, cracked tanks, clogged or damaged cores, or persistent overheating that isn't resolved by a coolant flush or thermostat replacement. If you're unsure, having your cooling system inspected by a technician can help confirm whether a repair or full replacement is the right call.
