Another tuning rarity from KATECOOL brings you better cooling performance and more comfortable driving experience! 

An auxiliary radiator in an automotive cooling system is a secondary radiator that works alongside the main radiator to help manage the engine's heat load more effectively. These are especially common in high-performance, turbocharged, or towing-capable vehicles, where additional cooling is needed.

Function of an Auxiliary Radiator

The auxiliary radiator provides additional heat dissipation capacity by:

1. Increasing coolant surface area for heat transfer.
2. Reducing coolant temperature before it returns to the engine or other systems.
3. Handling localized cooling needs (e.g., cooling specific components like the transmission,
   　 turbocharger, or battery systems in hybrids/EVs).
4. Operating in parallel or sequentially with the main radiator depending on temperature and system design.

Advantages of an Auxiliary Radiator

1. Improved Engine Cooling Efficiency
   　● Helps prevent overheating, especially under high-load conditions (e.g., racing, towing, mountain driving).
2. Enhanced Performance
   　● Cooler engine and intake temperatures allow the engine to run more efficiently and prevent power loss due
   　　to heat soak.
3. Extended Engine Life
   　● Reduces thermal stress on engine components, lowering the risk of heat-related wear or failure.
4. Supports High-Power Engines
   　● Necessary in turbocharged or supercharged engines that generate more heat than naturally aspirated engines.
5. Thermal Management for Additional Systems
   　● Can be used to cool hybrid battery systems, transmission oil, or even intercooler loops.
6. Improved Climate Control
   　● Reduces the thermal load on the HVAC system, indirectly enhancing cabin cooling efficiency.
