AA5052 Aluminum Radiator

This AA5052 Aluminum Radiator is designed to provide maximum cooling efficiency to help prevent premature engine failure. Its lightweight, high-heat-transfer aluminum construction features a tube-and-fin design that dramatically increases surface area, allowing heat to dissipate more efficiently.

This AA5052 Aluminum Radiator is at least 30%–45% more efficient than stock radiators. Most importantly, it has a much higher coolant capacity than stock units, helping the cooling system operate more efficiently and resist temperature surges in racing applications.

Made of AA5052 aircraft aluminum, stronger than other popular alloys and with increased corrosion resistance.
Brazed core technology to help ensure optimum performance and dependability.
AA5052 Aluminum 2 mm thick tanks and fittings for strength and durability.
Higher-density core with cooling rows spaced 3/8" apart, providing 25% more rows within the core than other aluminum radiators.
14–16 cooling fins per inch, providing approximately 1,500 more cooling fins than other aluminum radiators for increased heat dissipation.

Cooling Performance:
Stronger and higher coolant capacity than stock units.
Improves cooling by 35%–45%.

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.
