Product Details

Nissens 646816 is a radiator designed for the 2012-2015 Scion iQ and built from aluminum to help manage coolant temperature under normal driving conditions.

Common Cooling System Issues

• Overheating caused by a restricted or leaking radiator
• Coolant loss from corrosion or damaged core passages
• Reduced heat dissipation from an aging radiator assembly
• Temperature instability during stop-and-go driving
• Cooling performance decline on a high-mileage Scion iQ

Installation Notes and Tips

Verify radiator dimensions and mounting points against the original unit before installation. Inspect hoses, clamps, and coolant condition during replacement, and flush the system if contamination is present. Confirm the vehicle is a 2012-2015 Scion iQ before ordering part number 646816.
