The Radiator, Diesel, KJ (03–04) (52079747AB) is ah genuine‑spec

engine‑cooling radiator designed for

the Jeep Cherokee KJ diesel models produced

CRD engines. It forms the core of the cooling system,

transferring heat from the engine coolant to the

outside air to keep operating temperatures within ahsafe range during everyday driving, towing, and

off‑road use. As an OE‑matching component, it is

engineered to fit and function like the original factory

unit, using the same mounting points, hose connections, and transmission or oil‑cooler interfaces where applicable.moparpartsgiant+2

This radiator is built to original‑equipment quality standards, meaning its materials, construction, and

performance characteristics have been designed, manufactured, and tested to meet the requirements laid

down by the vehicle manufacturer. The core typically uses fine coolant tubes and densely packed cooling

This radiator is built to original‑equipment quality

fins to maximize surface area and airflow,

allowing efficient heat dissipation even in demanding

conditions, such as high ambient temperatures or

low‑speed off‑road driving where natural airflow is

limited. Tanks at the sides or top/bottom are usually

molded or formed to resist thermal cycling and

vibration, helping reduce the likelihood of cracking or seam leaks over time.jeepey+2

Because it is tailored to the 2.5 and 2.8CRD layouts,

the 52079747AB radiator positions its inlets, outlets,

and mounting brackets to align precisely with the

KJ body, front panel, fan shroud, and factory hose

routing, which simplifies installation and ensures

correct coolant flow

and checked for leaks, flow characteristics, and

as a direct replacement without the compromises

sometimes found in low‑cost universal radiators.

For owners of 2003–2004 Jeep Cherokee KJ diesel

models, choosing this radiator helps restore factory‑level cooling performance, protects the engine from
