If you’re looking to keep your engine cool and running smoothly, the CSF radiator is a solid choice. I’ve been in the automotive game long enough to know that a good radiator can make all the difference, and CSF really delivers. They’ve got a massive selection, covering over 3,200 different applications. Whether you drive an Acura or a Volkswagen, you’ll find a fit that works for you.

What I love about CSF is their commitment to quality. They offer radiators made of various materials—Copper-Brass, Plastic-Copper-Brass, Plastic-Aluminum, and All Aluminum—so you can choose what suits your ride best. They’ve been around for over 50 years, and with over 30 million units sold, it’s clear they know what they’re doing. These radiators are built to last and designed to meet high-performance standards, which is crucial if you’re pushing your vehicle to its limits.

One of the standout features is the OEM specified Plastic Tank-Aluminum Core construction. The tanks are made from virgin grade engineered plastic resins, and they’re glass filled for added strength and durability. That means you’re not just getting a radiator; you’re getting something that can handle the heat—literally. The gaskets are made from special grade EPDM rubber, so they can withstand extreme temperatures, down to -120°F. That’s a serious piece of engineering.

And let’s not forget about the fins—the heart of the radiator. They’ve got a high-performance multi-louvered design that maximizes cooling efficiency. Plus, each unit is 100% leak tested before it leaves the factory at 150% of operating pressure. You can trust that it’s going to hold up when you need it most. The packaging is also top-notch, passing a 10-foot drop test, so you know it’ll arrive in one piece.

Here are some specs that might interest you: it’s a crossflow radiator with a single row, measuring 26 5/16" in length, 19 5/16" in width, and 5/8" thick. The core and tank are both made of aluminum, which keeps things lightweight yet strong. The inlet is located on the lower passenger side with a diameter of 1 3/8", while the outlet is on the lower driver side at 1 1/2". It even includes a high-efficiency oil cooler that measures 13 3/4".

This radiator is a perfect fit for the Lexus RX330 from 2004 to 2006. Just a quick tip: when you’re swapping out your radiator, don’t forget to check the old pressure cap for any signs of wear. It’s a small detail, but it can save you a headache down the line.

In short, if you want a reliable radiator that can handle the heat and keep your ride cool, the CSF radiator is a great choice.
