Frequently Asked Questions

What is a radiator on a bus?

A bus radiator is a heat exchanger mounted in the vehicle's cooling system that dissipates heat from the engine coolant into the surrounding air. It consists of a core with thin fins and tubes, plus tanks that circulate hot coolant from the engine so it can cool before returning to prevent engine overheating during operation.
