When a radiator fails on a construction site, work stops. Excavator overheating, bulldozer cooling issues, crane downtime, and mining equipment failures can all disrupt productivity under load. A single overheating event can sideline a machine for days, and in heavy-duty operations, that downtime adds up fast.

King Radiator HD Inc. has been repairing, rebuilding, and manufacturing heavy equipment radiators for over 57 years. We serve construction fleets, mining operations, and industrial operators across Canada. Every job is handled with precision diagnostics, proper pressure testing, and a turnaround time built around your schedule  not ours.

From an excavator radiator leak on a job site in Ontario to a custom fabrication for discontinued mining equipment in Alberta, we handle it all.
