4JK1 4JJ1 Dmax Radiator

The radiator is a critical component in a truck's cooling system, designed to regulate engine temperature and prevent overheating. Its primary functions include:
1. Heat Dissipation
The radiator cools down the engine coolant (antifreeze mixture) after it absorbs heat from the engine.
Airflow (from driving or cooling fans) passes through the radiator’s fins and tubes, transferring heat away from the coolant.
2. Maintaining Optimal Engine Temperature
Prevents engine overheating, which can cause severe damage (e.g., warped cylinder heads, blown gaskets).
Helps the engine reach its ideal operating temperature quickly for better fuel efficiency and reduced emissions.
3. Supporting Heavy-Duty Performance
Trucks often operate under heavy loads, generating more heat—the radiator ensures stable cooling even during long hauls or uphill climbs.
Some heavy-duty radiators include oil coolers (for transmission or hydraulic systems) to handle additional heat.
4. Coolant Circulation Hub
Works with the water pump, thermostat, and hoses to circulate coolant in a closed loop, continuously cooling the engine.
