Performance Advantages

The aluminium construction of the NRF 58484 radiator offers a significant reduction in weight, which contributes to overall vehicle efficiency. The brazed fins provide a high surface area-to-volume ratio, enabling rapid heat dissipation and maintaining engine temperatures within safe limits during heavy load or prolonged operation.

Because the radiator is engineered for the specific coolant flow dynamics of the Nissan Cabstar and related models, it ensures optimal coolant circulation. This results in consistent cooling performance, reduced risk of overheating, and extended engine life.

Installation Guide

1. Preparation: Drain the existing coolant system completely. Remove the old radiator by disconnecting hoses, electrical connectors, and mounting brackets.
2. Mounting: Position the NRF 58484 radiator in place. Secure it with the supplied mounting hardware, ensuring all bolts are tightened to manufacturer specifications.
3. Reconnection: Reattach the coolant hoses, ensuring proper alignment of inlet and outlet ports. Connect any electrical sensors or temperature gauges that were previously attached.
4. Flushing & Refilling: Flush the cooling system with distilled water to remove air pockets. Refill with fresh engine coolant mixture (typically a 50/50 blend of antifreeze and water).
5. Testing: Start the engine and allow it to reach operating temperature while monitoring for leaks or abnormal temperatures. Verify that the radiator is functioning correctly by observing the coolant flow and temperature gauge.

Maintenance Tips

• Inspect the radiator fins regularly for debris or damage; clean with a soft brush if necessary.
• Check hose connections and clamps for tightness every 12,000 km or as recommended by the vehicle manufacturer.
• Replace coolant according to the vehicle’s service schedule to maintain optimal thermal performance.
