CSF 7031 Heavy-Duty All-Aluminum Radiator for Toyota Tundra 5.7L

CSF has over 5 decades of experience manufacturing radiators. So when it comes to keeping your engine cool and your Tundra/Sequoia running at its best, a CSF Heavy-Duty/High-Performance All-Aluminum Radiator is the obvious choice. Designed to perform on and off road, a heavy-duty performance radiator is a must-have for off-roaders, overlanders, and adventurers. This radiator features a 2-Row core with CSF's exclusive B-Tube Technology: Unlike a regular oval shape "O" type radiator tube, CSF uses a specially engineered tube in the shape of a "B". These "B-tubes" are carefully formed and then brazed over the seam to seal. CSF is able to use thinner and lighter aluminum material (with better cooling efficiency) because this design is actually stronger than normal "O" shape tubes that are welded. The design (inlet in the middle of the tube that is seam brazed) increases the heat transfer surface area of the tubes by approximately 15% over regular tubes - producing the efficiency of two smaller tubes vs. one large tube within the same space criteria. With "B-tubes" you are able to get "dual liquid laminar flow". CSF also uses ultra efficient multi louvered fins that are carefully and precisely aligned to maximize airflow through each radiator core. Fin specifications are carefully measured and calculated for each application, and tested for maximum heat rejection efficiency in our wind-tunnel lab. CSF manufactures the most advanced and efficient radiator in the industry for your Tundra/Sequoia. CSF uses innovative tube and fin technologies with industry-leading testing methods to maximize airflow and heat dissipation. The CSF #7031 Cooling product is designed to be a "Drop-In Fit" application. The product will install in the OEM Location with no modifications necessary unless otherwise noted or instructions are included in the product package. Please see the manufacturer repair manual for standard installation instructions. If you do not feel confident installing this product CSF recommends taking it to a qualified installation facility.

Keep your Toyota Tundra 5.7L operating at the right temperature with the CSF 7031 Heavy-Duty All-Aluminum Radiator. Built for demanding street, off-road, overlanding, and adventure applications, this high-performance radiator uses advanced tube and fin technology to improve heat transfer and maximize cooling efficiency. CSF has more than five decades of radiator manufacturing experience, delivering dependable cooling performance for drivers who require increased durability and thermal control.
The radiator features CSF’s exclusive B-Tube Technology, which uses specially engineered aluminum tubes with a seam-brazed design. This construction provides increased heat transfer surface area compared with conventional oval tubes while supporting efficient dual liquid laminar flow. The dual-row core is paired with ultra-efficient, multi-louvered fins that are precisely aligned to promote airflow through the radiator and improve heat dissipation. Each application is engineered and tested using advanced methods to help achieve consistent cooling performance under demanding conditions.
The CSF 7031 is designed as a direct drop-in replacement for the original radiator location, requiring no modifications unless otherwise noted in the installation instructions. It accepts compatible original equipment components, including quick-connect hoses, the air conditioning condenser, mounting brackets, and fan shroud. CNC-machined brackets and fittings support accurate installation and long-term durability, while the machined quick-connect inlet and outlet connections provide a secure fit. An all-aluminum race-style drain plug and hand-polished finish complete the premium construction. Always follow the vehicle manufacturer’s repair procedures, or have the radiator installed by a qualified professional if you are not comfortable performing the work.
