What This Radiator Helps Address

• Overheating caused by a worn or inefficient factory radiator
• Coolant temperature instability during stop-and-go driving
• Reduced cooling performance from aging plastic-tank or mixed-material units
• Heat buildup in work vans used for hauling, delivery, or fleet service
• Oil cooling needs where the integrated cooler is part of the original setup

Installation Notes and Tips

• Verify radiator dimensions, inlet and outlet locations, and transmission/oil cooler configuration before installation.
• 2012-2013 Nissan NV1500, NV2500, and NV3500 applications require a mini 16 psi cap per the fitment notes.
• Use the correct cap specification for the vehicle year and cooling system setup.
• Inspect hoses, clamps, and coolant condition during radiator replacement.
• Bleed the cooling system thoroughly after installation to remove trapped air.
