Installation Guide Overview

The radiator’s design allows for a quick replacement process. Below is an outline of the typical steps involved:

1. Drain Coolant: Safely drain existing coolant from the system.
2. Disconnect Hoses & Electrical Connections: Carefully detach the upper and lower radiator hoses, as well as any associated sensors or wiring.
3. Remove Old Radiator: Unbolt the mounting brackets and lift out the old unit.
4. Install NRF 53442 Radiator: Position the new radiator in place, secure with original bolts, and reconnect hoses and electrical components.
5. Refill & Bleed System: Refill with fresh coolant mixture and bleed air from the system to ensure proper circulation.
6. Test Drive: Verify that temperatures remain within safe limits during a short test drive.

Maintenance Tips for Longevity

• Regularly inspect hoses and clamps for signs of wear or leaks.
• Flush the cooling system every 30,000 miles (or as recommended by the vehicle manufacturer) to remove sediment that can clog fins.
• Use a high‑quality coolant compatible with aluminium radiators to prevent corrosion.
• Check radiator fan operation and ensure it engages at the correct temperature threshold.
