New CSF Jeep Wrangler (JL) & Gladiator (JT) Heavy-Duty Radiator

( CSF #7340 )

The Jeep Wrangler (JL) and pickup truck sibling the Gladiator (JT), are well known for their rugged reliability and out of the box off-road performance. However, even the best vehicles have their limits. Whether you are rock crawling, off-roading, or overlanding in extreme conditions, coolant temperatures can spike causing you to overheat. The new CSF Heavy-Duty All-Aluminum Radiator is the ultimate cooling solution for your Jeep.

Why Wrangler & Gladiator Owners Should Upgrade

Upgraded cooling systems are not just for off-road rigs and big haulers. Even basic mods/upgrades like oversized tires can increase strain on your engine in adverse conditions. The CSF Radiator provides extra protection that:

• Extends engine life by maintaining optimal coolant temperatures
• Improves towing capacity by enhancing cooling efficiency
• Eliminates performance limitations during demanding driving conditions
• Provides peace of mind with superior construction and durability

Design & Engineering

When engine coolant overheats, performance suffers and you are forced to stop driving or risk a cooling system failure. Having to stop and wait for your engine to cool down is more than just an inconvenience, it is a limitation that shouldn’t exist in modern SUVs and trucks. Especially not the legendary Wrangler.

An upgraded radiator helps eliminate the concern of overheating. These advanced designs feature larger 2-Row, 42mm aluminum cores which increase the fluid capacity of the radiators, and greatly improves heat dissipation. CSF’s Exclusive B-Tube Technology increases the heat transfer by approximately 15% over regular oval welded tubes. In addition, the ultra-efficient multi-louvered fins maximize airflow through the core for the best possible performance. The result is a dramatic temperature reduction under all driving conditions.

Key Features:

• 20-25% increase in heat transfer efficiency using CSF’s new 5mm Fin & Exclusive B-Tube Technology
• Improved cooling performance to support higher-boost and bigger-turbos, as well as additional load from gear, mods, and hard driving
• Engineered to withstand extreme conditions, providing reliability where it matters most
• Designed to work seamlessly with factory or aftermarket transmission coolers, intercoolers, etc.

CSF vs OEM

Jeep definitely learned some lessons from previous generations and gave the Wrangler and Gladiator a decent radiator. While the factory system seems to cope with modifications better than previous generations, more people are pushing these rigs harder than ever. Bigger turbos, more boost, heavier accessories, etc, all increase heat output of the motor.

Instead of waiting for your factory radiator to fail or putting up with power loss due to high engine temps, you can get ahead of the problem with the CSF Radiator. Upgrading to the CSF Radiator offers a lot of advantages including:

• 50% larger core volume than the factory radiator
• 20–25% increase in heat transfer efficiency using CSF’s exclusive 5mm Fin Technology
• 100% TIG welded Aluminum construction (compared to plastic end tanks crimped)
• Perfect for daily driving, towing, and off-road adventures

5mm Core Upgrade

While the first prototypes with CSF’s 6.5mm fin performed well in testing, CSF always seeks to offer the ultimate cooling solution. Before going into final production the design was updated to incorporate CSF’s latest 5mm fin technology which was introduced at the end of 2023. This new core specification offers even more heat transfer area and thermal efficiency than the tested prototypes. CSF is confident this radiator is ready to take on the most demanding conditions in the world.

Plug and Play Installation

CSF designed these Radiators to easily replace the OEM units. The Plug-and-Play “Drop-in Fit” installation should only take 2-3 hours and greatly improves the reliability and longevity of your engine.
