AA5052 Aluminum Shroud and Fan

The fan and AA5052 aluminum fan shroud are designed to improve airflow through the radiator and help direct heat away from the engine compartment.

The fan shroud securely houses the fan blades, helps improve airflow distribution, and reduces the risk of interference with nearby engine components.

1. Shuttered-design AA5052 aluminum fan shroud helps improve airflow efficiency.
2. S-Type blade fan supports Push or Pull Type installation with lightweight, durable plastic construction.
3. Includes a thermostat relay kit for temperature-controlled fan operation.

Thermostat Relay Kit

Universal fit for automotive electric fan applications.

Activates the electric fan by grounding it at the preset temperature.

Turn-On Temperature: 185°F
Turn-Off Temperature: 165°F

Wiring:
RED (+) — Connect directly to the battery.
WHITE — Connect to the ignition switch power source.
BLACK — Connect to the thermostat switch.
BLUE — Connect to the fan.

This setup is designed to run the fan as a puller, drawing air through the radiator.

Advantages

1. Made from aircraft-grade AA5052 aluminum with a raw aluminum finish for increased durability and corrosion resistance.
2. Brazed core technology for improved performance and dependability.
3. AA5052 aluminum 2 mm thick tanks and fittings for increased strength and durability.
4. Billet aluminum CNC-machined filler neck for improved durability.
5. CNC-machined radiator cap with engraved craftsmanship and anodized treatment.
6. OEM-style brass petcock drain.
7. Carefully crafted to OE standards for precise fit.

Description

This radiator is made from AA5052 aluminum, an Al-Mg alloy known for good corrosion resistance, strength, reliability, and workability.

This AA5052 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 increases surface area, allowing heat to dissipate more efficiently.

This AA5052 Aluminum Radiator is approximately 30%–45% more efficient than stock radiators and provides increased coolant capacity, helping the cooling system maintain stable temperatures and resist temperature surges in demanding 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.
