CSF has over 5 decades of experience in manufacturing radiators. So when it comes to keeping your engine cool and your Subaru running at its best, a CSF High-Performance All-Aluminum Radiator is the obvious choice.
The 42mm 2-Row aluminum core not only increases the fluid capacity of the radiator, but also improves the cores ability to dissipate heat.CSF’s Exclusive B-Tube Technologyimproves heat transfer by approximately 15% over regular oval welded tubes. In addition, the super-efficient multi-louvered fins maximize airflow through the core for the best possible performance.
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. Also, a larger core also helps when your radiator is covered in dust, dirt, or mud. While a radiator isn’t functioning at peak efficiency in there situations, the more overall cooling capacity you have the better.
Solid cooling upgrade over plastic end tank Radiator-2018 Outback Limited 2.5I
I hate how all the new radiators are plastic end tanks and they end up cracking. This is a thicker radiator all aluminum a bit hard to fit but a great, part nice welds and a thick core. I noticed on the trails it runs about 10-12 degrees cooler overall in the summer time anything to keep the temps down and make it more reliable is a win in my book.
