Aluminum Shroud and Fans

The fans and aluminum shroud help direct heat out of the engine compartment instead of pushing it toward the front of the engine. The shroud houses and secures the fan blades, helping prevent contact with nearby engine components and supporting smooth, consistent fan operation.

The S-type blade push/pull design helps improve airflow efficiency and cooling performance. Each fan uses an 80W motor to support engine cooling.

Description

This 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 aluminum radiator is approximately 40% more efficient than a stock radiator. It also has a higher coolant capacity, helping the cooling system operate more efficiently and resist temperature surges in racing 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.
