Radiator
The radiator removes heat from the engine coolant circuit. It normally uses larger coolant hose connections and may include plastic or aluminum tanks, drain provisions, mounting points, or transmission-oil cooling features depending on the application.
A/C condenser
The condenser rejects heat from high-pressure refrigerant in the air-conditioning circuit. Identification commonly depends on refrigerant line fittings, manifold layout, receiver-drier position, sensor ports, core dimensions, and vehicle application.
Intercooler
The intercooler reduces the temperature of compressed intake air on a turbocharged or supercharged engine. It uses charge-air connections and is matched by core construction, end-tank layout, connection size and position, and mounting arrangement.
Why names are not enough
A purchasing enquiry should state the part family as well as the OE number and vehicle. Photos and dimensions prevent confusion when several heat exchangers are installed close together at the front of the vehicle.
