Installation & Maintenance Guidance

Installing the Nissens 637619 Radiator is straightforward for technicians familiar with standard cooling system procedures. Key steps include:

1. Drain Existing Coolant: Safely remove old coolant to prevent contamination.
2. Remove Old Radiator: Detach hoses, brackets, and mounting hardware carefully.
3. Position New Radiator: Align the radiator with OEM mounting points and secure it using supplied fasteners.
4. Reconnect Hoses & Seals: Attach upper and lower coolant hoses, ensuring proper sealing to avoid leaks.
5. Refill Coolant System: Fill with recommended coolant mixture, purge air pockets, and perform a pressure test if necessary.

Regular maintenance involves inspecting for leaks, checking hose integrity, and flushing the cooling system every 30,000 miles or as per manufacturer guidelines. The radiator’s durable construction reduces the frequency of replacement compared to standard units.
