NRF 58848 Radiator, engine cooling

NRF 58848 Engine Cooling Radiator

The NRF 58848 radiator is a high‑performance cooling solution designed for the Renault Safran family of engines, including the 2.1L, 2.2L and 2.5L variants. It delivers reliable heat dissipation in demanding operating conditions while maintaining a lightweight profile.

Key Features

• Material: Aluminium alloy construction provides excellent thermal conductivity, corrosion resistance, and reduced weight compared to cast‑iron radiators.
• Design: The radiator incorporates a tightly welded water‑cooling fin structure, ensuring optimal airflow and heat transfer efficiency.
• Compatibility: Engineered for the Renault Safran I (B54) series, it also fits the Safran II models with minor adjustments. The radiator is available in both standard and EASY FIT versions to accommodate different mounting configurations.
• Dimensions: Compact size allows installation in tight engine bays without compromising cooling performance.
• Ease of Installation: The EASY FIT design features pre‑aligned mounting points and a streamlined shape, reducing assembly time for technicians.
• Durability: Designed to withstand high operating temperatures and pressure variations typical in automotive cooling systems.

Applications Across Markets

The NRF 58848 radiator is marketed under various names worldwide, reflecting its global reach. Below are the primary designations used in different regions:

Technical Specifications

The radiator’s performance is defined by a combination of fin density, tube diameter, and overall surface area. While exact numerical values are proprietary, the NRF 58848 achieves:

• High heat transfer coefficient due to dense fin spacing.
• Low pressure drop, ensuring efficient coolant flow without excessive pump load.
• Compatibility with standard automotive coolant mixtures (ethylene glycol or propylene glycol based).

Installation Guidance

For technicians, the NRF 58848 offers a straightforward installation process:

1. Remove the existing radiator by disconnecting hoses and draining coolant.
2. Align the mounting brackets with the pre‑drilled holes in the engine bay. The EASY FIT version includes alignment guides to prevent misplacement.
3. Secure the radiator using the supplied bolts, ensuring torque specifications are met to avoid leaks.
4. Reconnect hoses and refill coolant, then bleed the system to eliminate air pockets.
5. Verify operation by monitoring temperature gauges during a warm‑up cycle.
