If you're looking to keep your engine cool, you really can't go wrong with a CSF radiator. I’ve been around the block a few times with different radiators, and CSF stands out for a reason. They’ve got a massive range of over 3,200 models that fit everything from Acuras to Volkswagens. No matter if your setup is Copper-Brass, Plastic-Copper-Brass, Plastic-Aluminum, or All Aluminum, CSF has the right fit for you, matching the original equipment materials and style.

What really impresses me is the quality of these aftermarket radiators. They’re built to last, using the strongest components out there. CSF has been in the game for over 50 years, and they’ve sold more than 30 million units worldwide. That’s not just a number; it’s a testament to their reliability. Each radiator is carefully engineered and even wind tunnel tested to ensure it performs well under pressure. You can trust that they meet high performance standards, which is crucial for anyone who pushes their vehicle to the limit.

Now, let’s talk features. The construction is OEM specified with a plastic tank and aluminum core, which means it’s designed to withstand the heat. The tanks are made from virgin grade engineered plastic resins that are glass filled, giving them extra strength and durability. And those gaskets? They’re crafted from a special grade of EPDM rubber that can handle extreme temperatures—up to -120 degrees Fahrenheit. You won’t have to worry about leaks either; every unit is leak tested at 150% of its operating pressure before it leaves the factory.

Another thing I appreciate is the thoughtful packaging. CSF uses a “10-foot drop test” standard, so you know your radiator will arrive in one piece. During assembly, all components are installed, torqued, and tested, ensuring that you’re getting a product that’s ready to perform right out of the box.

In terms of specs, this particular model is a downflow radiator with a single row. It’s got an aluminum core that measures 18 11/16” in length, 30 5/16” in width, and 7/8” in thickness. The inlet location is upper center, and the outlet is on the lower passenger side, both with a diameter of 1 3/8”. Plus, it includes a high-efficiency concentric oil cooler that measures 14 3/4”.

For those of you with a Toyota Highlander from 2009 to 2011, this is a solid fit. Just a heads-up: when you’re swapping out the radiator, make sure to check the old pressure cap for any signs of wear. You’ll want to use a Micro, 16 psi cap for the best results.

In summary, if you’re serious about keeping your engine cool and running strong, the CSF radiator is a smart choice. It’s built tough, tested rigorously, and designed for real-world performance.
