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 cores 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.CSF manufactures the most advanced and efficient radiator in the industry for your 4th Gen Subaru Forester. CSF uses innovative tube and fin technologies with industry-leading testing methods to maximize airflow and heat dissipation.

Anyone who needs a new radiator should consider buying a CSF radiator. A CSF radiator and CSF cooling system offers the best performance for driving and racing enthusiasts. If you have a faulty radiator or are looking to upgrade to a high-performance radiator, a CSF radiator will get the job done. 

What is a CSF Radiator?

Today, their products are sold in over 60 countries throughout the world. Their US Aftermarket Division stocks over 1000 models that cover over 2100 applications for all popular Import vehicles.

CSF supplies radiators and condensers that are designed to meet or exceed original equipment (OE) engineering specifications. Their plants meet ISO 9000 standards and provide parts to OE manufacturers, and to top it all off - check out their industry leading warranty. Simply put, you cannot buy, sell, install or own a better value radiator or condenser.

Why Should I Buy a CSF Radiator? 

A CSF radiator offers a number of benefits over the competition. Below, we explain the main reasons why you should buy a CSF radiator.

CSF takes pride in the quality of its products and offers one of the best warranty’s in the industry. Please refer to the CSF warranty card in the shipping carton for details.

CSF warranty is applicable only to the original owner of the vehicle. Original paper work verifying the proof of purchase and pre-installation cooling system checklist signed by the professional installer is required to process warranty claims.

All warranty claims should be directed to the point of purchase. Due to CSF’s established agreements with Authorized CSF Warehouse Distributors, CSF is unable to handle and/or process warranty related calls/inquires from any individuals – all inquires/warranty related claims should be directed to the point of purchase or an authorized warehouse distributor.

Take care of your radiator, as under circumstances listed below the warranty will be void.

If the radiator is installed and is returned deformed (bulging tanks, warped core etc.), this is an indication that the radiator is the victim of some other problem and not the cause. The deformation is a result of the radiator being subjected to extremely high pressure and or temperature caused by any of the following reasons:Defective Pressure Cap, Defective Head Gasket, Defective Temperature gauge (incorrect readings), Defective Water Pump etc. Such units are not covered under the warranty.

If a radiator seems to have a “fit problem” there is the possibility that there is some confusion about a multi-fit radiator that might look different. Your nearest CSF WD can clarify the application, just give them a call. A perceived fit problem is not covered under warranty.

If a unit is damaged in shipping, please file a claim with the carrier. Damages caused during shipping, installation or handling are not covered under warranty.

Any repairs or alterations to the unit will automatically void the warranty.

Any form of abuse, including the use of improper coolant mixtures, damage caused by steam, corrosion etc and use on commercial vehicles voids the warranty. It is the vehicle owners’ responsibility to maintain the cooling system as specified in the owners manual.
