School Bus Radiators and Cooling System Parts

Auto-jet stocks replacement radiators, coolant tubes, and charge air coolers for Blue Bird, Freightliner, Ford, IC Bus, and Thomas Built school buses. Radiator core size and tank configuration are chassis-specific, so confirm the bus brand and engine before ordering.

Frequently Asked Questions

Does a radiator fit by bus brand or by chassis?

By chassis and engine combination. Some radiators cross multiple bus brands when they share a chassis platform. Most do not. Confirm before ordering.

What information do you need to confirm a radiator match?

Bus make, model year, and engine make and model. Provide the OE number if you have it, especially for shared-chassis platforms.

Do you stock coolant tubes and charge air coolers, or only radiators?

Both. Auto-jet stocks coolant tubes and charge air cooler components alongside radiators for the same engine platforms.
