CSF - 14-18 Subaru Forester High-Performance All-Aluminum Radiator

14-18 Subaru Forester High-Performance All-Aluminum Radiator

Whether you are running the stout 2.5L naturally aspirated motor or the hot 2.0L turbo engine off-roading and overlanding can be a lot harder on it than you might expect. Between dealing with traction loss steep inclines and additional weight of gear there is almost always more strain on the engine. The result is above average operating temperatures that the factory radiator can struggle to keep up with. Especially on the turbo models.

CSF has a long and successful track record with high-performance/heavy-duty off-road grade radiators. With most off-road vehicles the factory cooling components can easily become over stressed. This may be due to the demanding stress on the engine while climbing or dirt clogging up some of the cooling fins. The last thing you want is a radiator to fail while you?re far from civilization.

The 2-Row 42mm aluminum core not only increases the fluid capacity of the radiator but also improves the core's ability to dissipate heat. CSF?s Exclusive B-Tube Technology increases the 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. Additionally, the end tanks are made from high-grade aluminum and TIG welded to the core for extra strength. 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.
