If you're looking to keep your engine cool under pressure, you might want to check out the CSF radiator. These guys have been in the game for over 50 years, and they really know their stuff. With a lineup that covers more than 3,200 applications, you can bet they’ve got something for just about every ride out there—from your trusty Acura to a rugged Volkswagen.

What I appreciate about CSF is that they stay true to the original equipment (OE) style and materials, whether you’re dealing with Copper-Brass, Plastic-Copper-Brass, or all-aluminum radiators. It’s like they’ve taken the best of what’s out there and made it even better. Their aftermarket replacements are built like tanks, using the strongest components available, which is crucial when you’re pushing your vehicle to its limits.

These radiators are engineered to meet high-performance standards and are wind tunnel tested to ensure they won’t let you down when you need them most. The construction features OEM-specified plastic tanks paired with an aluminum core, which is a solid combo for durability and efficiency. And don’t worry about the heat—these tanks are made from virgin-grade engineered plastic resins that are glass-filled for extra strength. They’re designed to withstand extreme temperatures, all the way down to -120°F, thanks to special EPDM rubber gaskets.

On top of that, each radiator goes through a rigorous leak test at 150% of operating pressure before it leaves the factory. You can feel confident that it’s going to hold up. Plus, they come packaged to survive a 10-foot drop test, so you know they’ll arrive in one piece.

Here are some specs that might help you decide:

  • Radiator Type: Downflow
  • Rows: 2
  • Core Length: 23 1/4"
  • Core Width: 27 1/2"
  • Core Thickness: 2 1/16"
  • Core Material: Aluminum
  • Tank Material: Plastic
  • Inlet Location: Upper Driver Side
  • Outlet Location: Lower Passenger Side
  • Inlet Diameter: 1 1/2"
  • Outlet Diameter: 1 11/16"
  • Oil Cooler: 15 3/8" (high-efficiency Plate Type)

As for fitment, this radiator is perfect for the Lexus LX570 from 2010 to 2020 and the Toyota Land Cruiser from 2008 to 2021. Just a heads up—if you’re swapping out your radiator, take a moment to check the old pressure cap for any signs of wear. It’s a small detail that can make a big difference.

In short, if you want a reliable radiator that’s built to last and performs like a champ, CSF is definitely worth considering.

Take care of your radiator, as under circumstances listed below the warranty will be void.

If the radiator is installed and is returned deformed (bulging tanks, warped core etc.), this is an indication that the radiator is the victim of some other problem and not the cause. The deformation is a result of the radiator being subjected to extremely high pressure and or temperature caused by any of the following reasons:Defective Pressure Cap, Defective Head Gasket, Defective Temperature gauge (incorrect readings), Defective Water Pump etc. Such units are not covered under the warranty.

If a radiator seems to have a “fit problem” there is the possibility that there is some confusion about a multi-fit radiator that might look different. Your nearest CSF WD can clarify the application, just give them a call. A perceived fit problem is not covered under warranty.
