Cooling failures usually show up as a slow leak or an intermittent temperature gauge, and the cause is often a hose, a plastic tank seam or a thermostat that sticks open rather than the radiator itself. Read the description on each listing for the material and the tank construction, because plastic-tank and all-aluminium radiators are not interchangeable on every application.
Coolant should be matched to the specification the manufacturer calls for. Mixing long-life organic acid coolant with conventional green coolant shortens the life of the water pump and the radiator.
Heater cores appear under HVAC; hoses that route coolant to the heater are listed here because they fail, and are replaced, as part of the cooling circuit.
