How do you determine whether a car radiator needs to be replaced?
1. Obvious water leakage / seepage There are water stains, scale, and dampness in the upper and lower water chambers of the tank, at pipe connections, and around the core component. There has been a long-term presence of pink / green / yellow liquid (antifreeze) on the floor.

Common Faults and Maintenance of Automotive Radiators
Maintenance points: Always use proper antifreeze (do not use tap water directly); replace it every 2–3 years or every 40,000–60,000 kilometers. Regularly clean the surface of dust, cotton fluff, and insects to prevent blockages.

Classification and Main Materials of Automotive Radiators
According to the coolant flow direction: Longitudinal flow (upper and lower water chambers): Suitable for vehicles such as trucks with ample cabin height. Lateral flow (water chambers on both sides): Low-profile design, ideal for passenger cars with low hood designs.

Basic Definition and Function of Automotive Radiators
The automotive radiator is the core heat-exchange component of a water-cooled engine cooling system, installed behind the vehicle’s front grille. Its primary function is to cool the high-temperature coolant—after it has absorbed heat from the engine—by transferring heat to the oncoming airflow or to the forced air generated by the fan. This ensures that the engine consistently operates at its optimal temperature range of 85–95°C, preventing overheating and associated issues such as cylinder scoring and power loss.

How an automobile radiator works
Coolant circulation: The water pump drives the coolant to circulate between the engine’s water jacket and the radiator core.

The structural composition of an automobile radiator
Basic Components: Inlet/Outlet Chambers: Guide the coolant to flow into and out of the radiator. Radiator Core: The core heat-exchange area, composed of cooling tubes and fins. The primary material is aluminum alloy (accounting for over 80%); copper is more commonly used in commercial vehicle applications.

The core function of an automotive radiator
Temperature Control: Heat generated by the engine is transferred to the coolant via a heat exchanger, and then exchanged with air through the radiator core, thereby cooling the coolant. The cooled coolant is then circulated back to the engine, maintaining the engine's operating temperature between 80-100°C (in a liquid-cooling system) or dissipating heat through airflow (in an air-cooling system).

Automotive air-conditioning radiator, structure of finned radiators
Automotive air-conditioning radiator manufacturers offer finned radiators, which can be categorized by fin structure into: wrapped-fin type; staggered-fin type; welded-fin type; and rolled-fin type.

Automotive air-conditioning radiator, structure of finned radiators
Currently, steel-aluminum composite finned tubes are widely used. They combine the pressure resistance of steel pipes with the high thermal conductivity of aluminum, and are manufactured by bonding the two materials together on specialized machinery. Under operating conditions of 210℃, their contact thermal resistance is virtually zero.
