Frequently Asked Questions

What is a radiator in an excavator?

A radiator in an excavator is a heat exchanger that dissipates heat from the engine coolant, keeping the engine within safe operating temperatures during heavy-duty digging, lifting, and grading operations. It works alongside the oil cooler and charge air cooler to manage overall thermal load, and failure of the radiator can quickly lead to engine overheating and downtime.
