CSF 03-08 Infiniti FX45 4.5L OEM Plastic Radiator

This CSF radiator is built with a plastic tank and aluminum core, a common and effective design for keeping your 2003-2008 Infiniti FX45 with the 4.5L engine running cool. It's designed to be a direct replacement for your original radiator, meaning it should bolt right into place without needing any modifications.

CSF has been making cooling components for a while, and this radiator uses materials and construction methods similar to what came from the factory. The plastic tanks are durable for everyday driving, and the aluminum core helps dissipate heat effectively to prevent your engine from overheating, especially during stop-and-go traffic or when you're working the engine harder.

When you're replacing a radiator, it's a good idea to also check your coolant hoses and thermostat to make sure they're in good shape. Fresh coolant is also key to keeping your cooling system working its best.
