Application / Description

This lightweight aluminum radiator uses a tube-and-fin design to provide surface area for heat dissipation. Its 2-row racing-design core is intended to support engine cooling and temperature management in racing applications.

The original listing describes it as a high-performance racing specification with strength and cooling-efficiency benefits, greater coolant capacity than stock radiators, and resistance to temperature surges. It also describes the radiator as designed to provide maximum cooling efficiency to help prevent premature engine failure.

The original performance statements are “Improves Cooling by 35% to 45% Temperature” and “at least 40% more efficient than stock ones.” These figures are retained as supplied claims, not as verified test results.

Aluminum Shroud & Fans

The fan and aluminum shroud are designed to direct heat out of the engine compartment rather than toward the front of the engine. The shroud houses and secures the fan blades, helping prevent contact with other engine components and supporting smooth operation.

The assembly is intended to support stable engine operating temperatures. Proper maintenance helps maintain suitable engine operating conditions and driving quality.

The S-type blades use a push/pull design intended to support airflow and cooling. Each listed motor is rated at 90 W.

Fan Specifications

Diameter (Blade to Blade)	12 in.
Voltage	12 V DC
Power	90 W
Fan Thickness	2.5 in.
Number of Blades	10 S-type blades
Maximum Fan Airflow	2150 CFM (cubic feet per minute)
Maximum Fan Speed	2000 rpm ±10%
Blade Design	S-type, push/pull

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.
