CSF 03-06 Nissan 350Z 3.5L OEM Plastic Radiator

This is the CSF 2997 radiator, a direct replacement for your 2003-2006 Nissan 350Z with the 3.5L engine. It comes with the plastic tanks and aluminum core, just like the original equipment. This radiator is designed to fit right into your existing cooling system setup, making it a straightforward option when it's time to replace your old, leaky, or clogged radiator.

When your 350Z's radiator starts to fail, you'll often notice coolant leaks, especially around the plastic tanks where they meet the aluminum core. Over time, the plastic can become brittle and crack, or the seals can fail. This CSF radiator uses a similar construction to the factory unit, with durable plastic tanks bonded to an efficient aluminum core. This design helps keep costs down while still providing reliable cooling performance for your V6 engine. It's a well-built part that addresses the common failure points of the original radiator.

Replacing a radiator is a common maintenance task, and this unit is designed to be a direct fit, meaning you won't need any special modifications to install it. Just drain your old coolant, unbolt the old radiator, transfer any necessary fittings or fan shrouds, and install the new one. Make sure to refill with the correct type of coolant for your Nissan and bleed the air out of the system according to the service manual.
