CSF Hi-Perf Aluminum Radiator

2007–2018 Jeep Wrangler JK 3.8L / 3.6L

Part #: 7036

Overview

The CSF Hi-Performance Aluminum Radiator is engineered to provide superior cooling for Jeep Wrangler JK models from 2007 to 2018 equipped with 3.8L or 3.6L engines. With over five decades of radiator manufacturing expertise, CSF delivers a heavy-duty, high-performance solution designed to keep your engine running cooler under demanding conditions. This radiator is ideal for off-road enthusiasts, overlanders, and daily drivers who require reliable cooling performance both on and off the pavement.

Built to withstand the rigors of rugged terrain and extended use, the CSF radiator ensures your Wrangler maintains optimal operating temperatures, preventing overheating during intense driving scenarios. Its robust construction and advanced cooling technology make it a vital upgrade for anyone looking to enhance their vehicle’s thermal management.

Key Features

CSF’s Hi-Performance Aluminum Radiator incorporates innovative design elements and premium materials to maximize cooling efficiency and durability. Key features include:

• Exclusive B-Tube Technology: Unlike conventional oval "O" type tubes, CSF uses specially engineered "B"-shaped tubes that increase heat transfer surface area by approximately 15%, improving cooling efficiency within the same core size.
• Dual Liquid Laminar Flow: The unique tube design allows for dual liquid flow, enhancing heat dissipation and overall radiator performance.
• 2-Row Core Construction: Provides a balance of cooling capacity and airflow, optimized for the Jeep Wrangler JK’s engine requirements.
• Multi-Louvered Fins: Precisely aligned fins maximize airflow through the radiator core, improving heat rejection and engine cooling.
• Lightweight, Heavy-Duty Aluminum: Uses thinner, lighter aluminum material without sacrificing strength, contributing to improved vehicle efficiency and durability.
• Seam Brazed Tubes: Ensures superior structural integrity compared to welded tubes, enhancing longevity and resistance to leaks.
• Tested in Wind Tunnel Lab: Fin and tube configurations are rigorously tested to ensure maximum heat rejection efficiency.

Construction & Design

The CSF Hi-Performance Radiator is crafted from premium all-aluminum materials, combining lightweight construction with exceptional strength. The innovative B-Tube design is seam brazed rather than welded, allowing the use of thinner aluminum that is both lighter and more efficient at heat transfer. This advanced engineering results in a radiator core that is stronger and more durable than traditional designs.

Each radiator is meticulously assembled with multi-louvered fins that are carefully aligned to optimize airflow and heat dissipation. The 2-row core layout balances cooling capacity with airflow resistance, ensuring your Jeep’s engine remains within safe operating temperatures even under heavy loads or extreme conditions.

Installation & Fitment

This radiator is a direct fit replacement for 2007 through 2018 Jeep Wrangler JK models equipped with 3.8L or 3.6L engines. Designed to match OE mounting points and hose connections, installation is straightforward with no modifications required. Whether you are upgrading your cooling system for enhanced performance or replacing a worn factory radiator, the CSF Hi-Performance Radiator offers a hassle-free installation experience.

What's Included
