Over the years, the Forester XT community has grown, and with it, the demand for parts. CSF’s Australian Distributor (ProSpeed Racing) specifically requested this radiator after a lot of poor experiences with radiators from other companies. Several other dealers echoed this request so we fast tracked production to bring these to market as soon as possible. Now, CSF is pleased to announce the new 2nd Gen Forester XT Manual Transmission High-Performance All-Aluminum Radiator.

CSF has over 5 decades of experience manufacturing radiators. So when it comes to keeping your engine cool and your Forester XT running at its best, a CSF High-Performance All-Aluminum Radiator is the obvious choice. Designed to perform on the street or at the track, a performance radiator is a must-have for both high horsepower builds as well as race vehicles which need added cooling performance in motorsports environments. This radiator features a 2-Row core with CSF's exclusive B-Tube Technology: Unlike a regular oval shape "O" type radiator tube, CSF uses a specially engineered tube in the shape of a "B". These "B-tubes" are carefully formed and then brazed over the seam to seal. CSF is able to use thinner and lighter aluminum material (with better cooling efficiency) because this design is actually stronger than normal "O" shape tubes that are welded. The design (inlet in the middle of the tube that is seam brazed) increases the heat transfer surface area of the tubes by approximately 15% over regular tubes - producing the efficiency of two smaller tubes vs. one large tube within the same space criteria. With "B-tubes" you are able to get "dual liquid laminar flow". CSF also uses ultra efficient multi louvered fins that are carefully and precisely aligned to maximize airflow through each radiator core. Fin specifications are carefully measured and calculated for each application, and tested for maximum heat rejection efficiency in our wind-tunnel lab.

The CSF Forester XT radiator is a true "Drop-in fit" design requiring no modifications to install. OE style brackets are all CNC machined and welded for the best durability possible. Inlet/Outlet connections are designed to match the OE connections so you can reuse OEM hoses or aftermarket. Trust the cooling experts at CSF for the best performing, highest-quality, and most reliable radiators.

Design & Engineering

CSF has long been one of the most popular manufacturers for High-Performance Subaru Radiators. This history includes making many private label oil coolers, intercoolers, and more for some of the most popular Subaru Tuning Companies. So whether you are racing on track, rally racing in the dirt, overlanding, or just doing some spirited driving through country roads, a high-performance radiator will help keep your Forester XT running at optimal temperatures.

Having a High-Performance Radiator also becomes very important when converting from a factory style top mount intercooler to a front mount intercooler system. Moving the intercooler in front of the radiator restricts airflow and increases the temperature of air flowing through it. These factors are often overlooked but you need to compensate for both air restriction and higher air temperatures flowing through the radiator. The best solution is to upgrade to a CSF High-Performance Radiator.

CSF vs OEM

The original OE radiator from Subaru is a plastic tank with a single row aluminum core design. While this is generally accepted as good quality and durable, it is not the best option for high horsepower builds or hard driving. Also, Turbo cars get hot, and the EJ25 engine is no exception. Anything you can do to help keep coolant temps in check will improve the longevity of your engine and help the car run smoothly.

The CSF 42mm 2-Row aluminum core is more than double the size of the OEM core. A thicker core, second cooling row, and increased fluid capacity drastically improves the amount of heat the system can absorb and dissipate. 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 cooling performance.

The TIG-Welded 100% All Aluminum construction increases the overall strength of the radiator. This improves durability and longevity so you can be confident it will hold up to hard driving conditions. The CSF radiator mounts in the factory location and requires no modifications or cutting.
