Overview: Radiator Repair
Start with the part nobody wants to hear. If the temperature gauge is climbing into the red, or steam is coming out from under the hood, stop driving. Pull over, shut the engine off, and get it towed. An engine that overheats once and is shut down usually survives. An engine driven home hot needs a head gasket at the cheap end.
The hardware in this category is the radiator itself, the hoses, the water pump, the thermostat, the cooling fans, the pressure cap and the heater core buried in the dash. Leaks show up where the plastic end tanks crimp onto the aluminum core, at hoses that have gone hard and shiny, or at the water pump's weep hole. Blockage is the quieter failure: the car runs fine in town and creeps hot pulling a grade in traffic.
Most radiators today are replaced rather than repaired, because a new one costs less than the hours it takes to open an old one. Shops that recore still exist and they earn their keep on trucks, tractors and older cars with brass radiators worth saving.
Use the state and city lists below. These shops often sit near truck routes and industrial streets rather than retail strips.
