Buy Radiator (KJ 3.7) (52080118AA)

The Radiator (KJ 3.7) (52080118AA) is an important cooling system component designed for vehicles

equipped with the 3.7-liter PowerTech V6 engineh in the Jeep Liberty (KJ) platform. This radiator is

commonly used in Jeep Liberty and Jeep Cherokee models produced between 2002 and 2005. It plays a

h

operation. By ensuring efficient heat dissipation, the radiator helps protect the engine from overheating and supports consistent vehicle performance.

The radiator functions by circulating engine coolant through a network of tubes inside the radiator core. As

the heated coolant enters the radiator, it passes through thin aluminum tubes surrounded by cooling fins.

This continuous cycle keeps the engine operating

within the recommended temperature range and prevents thermal damage to critical components.

The 52080118AA radiator is typically constructed with an aluminum core and reinforced plastic end tanks.

remaining light weight. resistance to heat and pressure inside the cooling system. This combination of materials ensures efficient heat transfer and long-lasting durability under normal driving conditions.

The longevity of the transmission system.

In terms of design, the radiator features a cross-flow configuration in which coolant travels horizontally

across the core. This layout improves cooling efficiency by allowing coolant to remain in the radiator

longer, maximizing heat exchange with the surrounding airflow.

include an integrated automatic transmission cooler, which helps regulate the temperature of transmission

fluid and contributes to the longevity of the transmission system.

The typical core dimensions for this radiator are approximately 20 inches by 20 inches with a thickness of

about 26 mm, providing sufficient cooling capacity for the 3.7L engine. The inlet and outlet hose

through the engine and cooling system.

The Radiator (52080118AA) is manufactured to meet OEM standards, making it a direct-fit replacement

for the original radiator installed in compatible Jeep vehicles. This means it can usually be installed

without modifications, using factory mounting points and standard hose connections.

maintain stable engine temperatures. Its durable construction, efficient heat-dissipation design, and

compatibility with Jeep Liberty 3.7L models make it an essential part for ensuring engine protection, performance, and long-term reliability.
