Description

This TSM® AA5083 aluminum radiator is designed to provide maximum cooling efficiency and help prevent premature engine failure. Its lightweight, high-heat-transfer aluminum construction features a tube-and-fin design that significantly increases the surface area, allowing heat to dissipate more efficiently.

This AA5083 aluminum radiator is approximately 30%–45% more efficient than a stock radiator, helping the cooling system operate more efficiently and resist temperature surges in racing applications.

Radiator Construction Features

Made of AA5083 aircraft-grade aluminum.
Brazed core technology.
3.2 mm thick tanks and fittings.
6 mm fin height.
Higher-density core with cooling rows spaced 3/8" apart.
14–16 cooling fins per inch.

AA5083 Aluminum Fan Shroud Performance Advantages

Premium AA5083 marine-grade aluminum construction: High-strength, corrosion-resistant alloy provides superior durability compared with standard aluminum and is suitable for harsh engine-bay environments.
Sealed, high-efficiency airflow design: The precision-fitted shroud reduces air leakage around the radiator core and directs fan airflow through the cooling fins for 30%–50% better heat rejection than unshrouded setups.
Aerodynamic vented structure: The optimized vent design reduces turbulence, helps prevent hot spots, and efficiently expels hot air from the engine compartment.
Engine protection and structural reinforcement: The shroud helps secure the fan blades, prevents contact with nearby engine components, and reinforces the radiator core against vibration and road-debris damage.
Maintains optimal engine conditions: Provides consistent and even cooling to help preserve engine performance, extend service life, and improve overall ride quality.
Direct bolt-on fitment: Precision-machined for straightforward installation without modification, creating a clean and professional engine-bay finish.

12" 24V Brushless Cooling Fan Features

High-performance brushless motor: Eliminates brush friction and wear for up to 10 times longer service life than traditional brushed fans, with consistent and reliable performance.
Powerful axial cooling design: The compact, high-torque 12-inch fan delivers more than 1,800 CFM of airflow for high-horsepower engines, turbocharged builds, and heavy-duty applications.
Quiet, vibration-free operation: Precision-balanced blades and motor provide smooth, low-noise operation, even during continuous use.
Built for harsh environments: The sealed motor housing resists dust, moisture, and extreme temperatures and is engineered for continuous-duty operation.
Maintenance-free performance: No brushes to replace and no regular maintenance required.
Energy-efficient operation: Low power draw reduces the load on the electrical system, making the fans suitable for 24V commercial, performance, and off-road applications.

What is a radiator?

The radiator's job is to remove heat from the engine's coolant. As hot coolant passes through the radiator it is cooled before returning to the engine, where it absorbs heat and returns to the radiator. This cooling process keeps the engine from overheating.

How does the radiator work?

The engine generates heat when it is running; this heat must be removed to prevent damage to the engine. Coolant circulates throughout the engine and absorbs this heat. The water pump pushes the coolant through the radiator (where it is cooled) and returns it to the engine once more to absorb the engine’s heat, before returning it to the radiator to be cooled again. When a vehicle is traveling fast, rushing air flows through the radiator and cools the engine. When a vehicle is in stop-and-go traffic or stuck at a traffic light, the engine’s cooling fan pushes air through the radiator.

Can I drive with a radiator problem?

A sub-performing Radiator has far reaching effects. An inoperative heater, loss of coolant, or engine damage from overheating could occur. Overheating causes severe damage to an engine, including failure of the head gasket. Continuing to drive an overheating vehicle may disable the motor.

How often do radiators need to be replaced?

Replacement intervals vary greatly by vehicle and driving conditions. We typically see the radiator replaced at approximately 80,000 miles. While the radiator does not wear the same as a belt or brake pad, the repeated heating and cooling cycles the radiator experiences will eventually cause the degradation of its plastic end-tanks and seals.

How is a radiator replaced?

To replace the Radiator, the technician will drain the coolant from the cooling system and remove the Radiator and radiator hoses from the vehicle. This may also require removal of plastic shrouds and other engine bay cladding to reach the part. Where applicable, the cooling fan switch and electric cooling fan assemblies are transferred to the new Radiator. Once the new Radiator is installed, the cooling system is refilled with fresh coolant and the system is bled of any air, then rechecked to ensure all leaks have been fixed.
