If you’re looking to keep your engine running cool and happy, the CSF Engine Coolant Radiator is a solid choice. This isn’t just any radiator; it’s designed to meet OE standards, which means it fits right in with your Honda Fit from 2009 to 2013 without any fuss. Trust me, keeping your cooling system in top shape is crucial for the longevity of your engine, and this radiator is built to deliver.

Let’s talk specs for a moment. This downflow radiator features a single row design with a core length of 13 3/4 inches and a width of 28 1/16 inches. It’s got a core thickness of 7/8 inches, which is just the right balance for efficient heat exchange. The core is made from aluminum, ensuring it’s lightweight yet durable, while the tanks are crafted from high-quality plastic that’s engineered to withstand the test of time. The inlet is conveniently located on the upper driver side, with the outlet on the lower passenger side, both sporting a diameter of 1 1/8 inches. Plus, there's a high-efficiency concentric oil cooler that measures 12 13/16 inches, just to give your engine that extra boost.

What really sets this radiator apart is its construction. CSF uses virgin grade engineered plastic resins that are glass-filled for added strength. The gaskets are made from special grade EPDM rubber, which can handle extreme temperatures—up to -120 degrees Fahrenheit. And the fins? They feature a multi-louvered design that enhances cooling performance, making sure your engine stays at just the right temperature even on those hot summer days.

Every CSF radiator is thoroughly leak tested at 150% of operating pressure before it leaves the factory, so you know you’re getting a product that won’t let you down. They even go the extra mile with packaging that can withstand a 10-foot drop test. It’s all about making sure you receive a radiator that’s ready to hit the road without any worries.

CSF has been in the game for over 50 years, and they really know their stuff. They’ve sold over 30 million units worldwide, and their radiators are engineered and wind tunnel tested for top-notch cooling performance. With three manufacturing facilities and a team of experienced professionals, CSF is committed to using the best technologies and materials available. It’s not just about making a radiator; it’s about creating a cooling system that you can trust.

Just a quick note: when you’re swapping out your radiator, don’t forget to check the old radiator pressure cap for any signs of wear. It’s a small detail that can make a big difference in your cooling system’s performance. And remember, you’ll need a mini 16 psi cap to complete the setup.

In short, if you’re serious about keeping your Honda Fit running smoothly, this CSF radiator is a no-brainer. It combines quality, efficiency, and durability, making it a smart investment for any car enthusiast or everyday driver.
