Kenworth T700 Radiators

Frequently Asked Questions About Kenworth T700 Radiators

Will this radiator fit my Kenworth T700 without modifications?

Radiators are built to match specific engine and cooling system configurations, so fit can vary based on your truck's engine size, cab configuration, and cooling package. Always check the part number against your truck's VIN or existing radiator specifications before ordering, and reach out to our team if you're unsure whether a particular unit matches your setup.

What material is the radiator core and tanks made from, and how does that affect durability?

Most heavy-duty radiators use an aluminum core paired with either aluminum or plastic end tanks. Aluminum cores offer strong heat transfer and resistance to corrosion, while the tank material can influence long-term durability under vibration and heat cycling. Check the product description for specific core and tank materials so you know what you're getting.

Is this a direct OEM replacement or an aftermarket unit?

Our listings typically note whether a radiator is OEM, OEM-surplus, or a quality aftermarket replacement. Both options are built to restore proper cooling performance, but OEM units are made to original factory specifications while aftermarket radiators are designed to match fit and function at a different price point. Review the product details to confirm which type you're purchasing.

What should I check before installing a replacement radiator?

Before installation, inspect your mounting brackets, hoses, and fan shroud for wear or damage, since these components often need to be reused or replaced alongside the radiator. It's also a good idea to flush the cooling system and inspect the fan clutch and belts, as a new radiator won't fix issues caused by other failing cooling system parts.

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

Common signs that point to replacement rather than repair include persistent leaks at the core or seams, visible corrosion, bent or crushed fins that restrict airflow, or repeated overheating even after a repair. If you're seeing recurring issues after a patch or repair, a full replacement is usually the more reliable long-term solution.
