Radiator for Iveco Cavallino – OE: 503346759 Specification

Short Description:

The OE number 503346759 refers to a dedicated water-cooled radiator designed specifically for the Iveco Cavallino series commercial vehicles. It is engineered to match the diesel engine cooling system of this model, effectively meeting the heat dissipation needs under heavy-duty operating conditions. This article details its complete parameter configuration and performance characteristics.

In terms of basic adaptation information, this radiator is exclusively suitable for the Iveco Cavallino series light and medium-duty commercial vehicles, including van and cargo chassis, perfectly matching the original diesel powertrain of the model. The OE number 503346759 serves as the unique identifier authorized by Iveco, which is the core basis for selecting replacement parts in after-sales service. As a water-cooled engine radiator, its primary function is to circulate coolant to dissipate heat, ensuring the engine operates at a stable working temperature.

Regarding core dimensional parameters, the radiator core measures approximately 650mm in length, 440mm in width, and 32mm in thickness, which is precisely tailored to the engine compartment space of the Cavallino model, guaranteeing efficient air flow. Both the water inlet and outlet have a diameter of 32mm, with standard flange-type interfaces that match the original cooling pipelines, ensuring reliable sealing and easy disassembly and assembly. It adopts the original standard pin mount installation, with 4 sets of positioning holes aligned accurately with the vehicle frame, allowing direct replacement without any modification.

Core Length

440mm

Core Width

32mm

Core Thickness

32mm

Inlet / Outlet Diameter

The radiator core dimensions are precisely tailored to the engine compartment space of the Cavallino model, guaranteeing efficient air flow. Both the water inlet and outlet feature standard flange-type interfaces that match the original cooling pipelines, ensuring reliable sealing and easy disassembly and assembly.

It adopts the original standard pin mount installation, with 4 sets of positioning holes aligned accurately with the vehicle frame, allowing direct replacement without any modification.

Material & Structural Design

Core Structure

All-aluminum tube-and-fin structure with brazing technology — high thermal conductivity, corrosion resistance, and lightweight.

Water Chambers

High-strength engineering plastic, withstanding -40℃ to 120℃, aging-resistant with built-in flow guide structure.

Flow Design

Crossflow design — coolant flows horizontally, cooperating with the front fan and airflow, superior to vertical flow type.

Performance & Operating Parameters

200kPa

(29 psi)

Rated Working Pressure

80~120kW

Engine Power Range

≥15kW

Continuous Heat Dissipation

≤-35℃

Coolant Freezing Point

≥108℃

Coolant Boiling Point

Compatible with Iveco original long-life coolant (ethylene glycol type), allowing direct replacement without changing the cooling system medium. Meets the pressure requirements of the cooling system when the engine is running at high load, preventing leakage and pipe burst.

Additional Configuration & After-Sales Service

Pure engine water-cooled radiator — no integrated transmission oil cooler or engine oil cooler, adapting to the original cooling system layout of the Cavallino model.

Plastic drain valve standard at the bottom — facilitating coolant replacement and system venting for easy maintenance.

Complies with original OE specifications — no adjustment of cooling system parameters required after replacement.

Warranty period meets the commercial vehicle parts standard — usually 12 months or 100,000 kilometers. As an original-level replacement part, it ensures long-term stable operation of the vehicle.
