Installation Notes
This is a direct bolt-in replacement that uses your existing hoses and mounting hardware. Before installing your new radiator, flush the entire cooling system thoroughly to remove any scale or debris that could contaminate the fresh unit. While you’ve got the system apart, it’s a smart time to replace the thermostat and check all hoses for cracks.
