Features & Specs

• Efficiency is key in off-roading as speeds tend to be lower overall so you end up relying on the fans to move most of the air over the radiator.
• While the factory fans do a decent job pulling air through the radiator core, it is still less airflow than you'd typically see in city driving.
• A larger and more efficient core will keep your engine temps in check and keep your engine running strong.
• While a radiator isn't functioning at peak efficiency in there situations, the more overall cooling capacity you have the better.
• In contrast, the OEM crimped onto plastic end tank design is much weaker and creates a weak point where failure is more likely.
• Because the CSF radiator is designed as a true plug-and-play drop-in fit application, installation requires absolutely no modifications, trimming, or cutting.
• Brand: CSF
• Part number: CSF7213

A new radiator is a good time to flush the system, replace hoses and the thermostat, and refill with the correct coolant.
