What is included with this CSF radiator?

This radiator includes the all-metal radiator with a 2-row, 42mm core and a built-in transmission oil cooler. It also comes with pre-cut adhesive foam strips for fan shroud sealing.

How does the built-in transmission cooler help?

The heavy-duty 5-plate transmission cooler is integrated into the radiator tank. It helps manage the extra heat generated by towing, low-gear crawling, or vehicles with oversized tires, which can reduce the effective gear ratio and make the transmission work harder.

What makes this radiator stronger than the OEM unit?

This CSF radiator features TIG-welded aluminum end tanks, which are significantly stronger than the OEM's crimped plastic design. The all-aluminum construction and advanced core technology also contribute to its overall durability and cooling efficiency.

Product Details

When you're looking to replace the original radiator in your 2003-2009 Lexus GX470 or 2003-2009 Toyota 4Runner with the 4.7L V8 engine, this all-metal radiator from CSF is a solid option. It comes with the radiator itself, featuring a 2-row, 42mm thick aluminum core designed to handle more heat than the stock unit. You also get a heavy-duty, 5-plate transmission oil cooler built right into the tank, along with pre-cut adhesive foam strips to help seal your fan shroud for better airflow efficiency.

This CSF radiator is built tough. The core uses CSF's exclusive B-Tube technology, which increases heat transfer by about 15% compared to standard oval tubes, and the multi-louvered fins are designed to maximize airflow. The end tanks are made from high-grade aluminum and are TIG welded to the core for extra strength, a much more reliable connection than the OEM's crimped plastic tanks. Because it's designed as a true plug-and-play, drop-in fit, installation requires no modifications to your vehicle.

The 4.7L V8 engine in these SUVs is known for being reliable, but the original radiator can still fail, especially after many years and miles. If you use your vehicle for towing, crawling, or have installed larger tires, the added stress on the engine and transmission generates more heat. This CSF radiator is built to manage that extra heat, offering improved cooling performance and a more robust construction than the factory part.
