upgrade for the Focus RS. They needed a solution to the excessive coolant temperatures many of their customers were seeing. Especially those running their higher power racing engines. CSF engineered the radiator for the best possible performance and fitment. These popular systems are now available through CSF’s world wide Dealer and Distributor network.\u003c\/p\u003e\n\u003cp\u003eWhile the radiator was designed for super high performance race engines, anyone with a Focus RS can benefit from upgrading. Even modest power increases and hard driving can put a strain on the factory cooling system. The CSF Radiator is the ultimate cooling solution for any Focus RS owner.\u003c\/p\u003e\n\u003cp\u003eCSF vs OEM\u003c\/p\u003e\n\u003cp\u003eThe original OE radiator from Ford is a plastic tank with a single row aluminum core design. While this is pretty standard and works fine for the average customer, it is not the best option for high horsepower builds or hard driving. Also, Turbo cars get hot, and the 2.3L EcoBoost 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.\u003c\/p\u003e\n\u003cdiv class=\"kadence-blocks-gallery-item-inner\"\u003e\n\u003cfigure class=\"kb-gallery-figure kb-gallery-item-has-link kadence-blocks-gallery-item-hide-caption\"\u003e\u003ca aria-label=\"Display this image in a lightbox\" class=\"kb-gallery-item-link\" href=\"https:\/\/y7y6i2a9.delivery.rocketcdn.me\/wp-content\/uploads\/2025\/04\/G1FZ-8005_1.jpg\"\u003e\n\u003cdiv class=\"kb-gal-image-radius\"\u003e\n\u003cdiv class=\"kb-gallery-image-contain kadence-blocks-gallery-intrinsic\"\u003e\u003cimg srcset=\"https:\/\/y7y6i2a9.delivery.rocketcdn.me\/wp-content\/uploads\/2025\/04\/G1FZ-8005_1.jpg 900w, https:\/\/y7y6i2a9.delivery.rocketcdn.me\/wp-content\/uploads\/2025\/04\/G1FZ-8005_1-300x200.jpg 300w, https:\/\/y7y6i2a9.delivery.rocketcdn.me\/wp-content\/uploads\/2025\/04\/G1FZ-8005_1-768x512.jpg 768w, https:\/\/y7y6i2a9.delivery.rocketcdn.me\/wp-content\/uploads\/2025\/04\/G1FZ-8005_1-600x400.jpg 600w\" sizes=\"(max-width: 900px) 100vw, 900px\" data-ll-status=\"loaded\" data-lazy-src=\"https:\/\/y7y6i2a9.delivery.rocketcdn.me\/wp-content\/uploads\/2025\/04\/G1FZ-8005_1.jpg\" data-lazy-sizes=\"(max-width: 900px) 100vw, 900px\" data-lazy-srcset=\"https:\/\/y7y6i2a9.delivery.rocketcdn.me\/wp-content\/uploads\/2025\/04\/G1FZ-8005_1.jpg 900w, https:\/\/y7y6i2a9.delivery.rocketcdn.me\/wp-content\/uploads\/2025\/04\/G1FZ-8005_1-300x200.jpg 300w, https:\/\/y7y6i2a9.delivery.rocketcdn.me\/wp-content\/uploads\/2025\/04\/G1FZ-8005_1-768x512.jpg 768w, https:\/\/y7y6i2a9.delivery.rocketcdn.me\/wp-content\/uploads\/2025\/04\/G1FZ-8005_1-600x400.jpg 600w\" class=\"wp-image-30968 entered lazyloaded\" data-id=\"30968\" data-light-image=\"https:\/\/y7y6i2a9.delivery.rocketcdn.me\/wp-content\/uploads\/2025\/04\/G1FZ-8005_1.jpg\" data-full-image=\"https:\/\/y7y6i2a9.delivery.rocketcdn.me\/wp-content\/uploads\/2025\/04\/G1FZ-8005_1.jpg\" alt=\"\" height=\"600\" width=\"900\" src=\"https:\/\/y7y6i2a9.delivery.rocketcdn.me\/wp-content\/uploads\/2025\/04\/G1FZ-8005_1.jpg\" decoding=\"async\"\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/a\u003e\u003c\/figure\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"kadence-blocks-gallery-item-inner\"\u003e\n\u003cfigure class=\"kb-gallery-figure kb-gallery-item-has-link kadence-blocks-gallery-item-hide-caption\"\u003e\u003ca aria-label=\"Display this image in a lightbox\" class=\"kb-gallery-item-link\" href=\"https:\/\/y7y6i2a9.delivery.rocketcdn.me\/wp-content\/uploads\/2025\/04\/7239_1.jpg\"\u003e\n\u003cdiv class=\"kb-gal-image-radius\"\u003e\n\u003cdiv class=\"kb-gallery-image-contain kadence-blocks-gallery-intrinsic\"\u003e\u003cimg srcset=\"https:\/\/y7y6i2a9.delivery.rocketcdn.me\/wp-content\/uploads\/2025\/04\/7239_1.jpg 1920w, https:\/\/y7y6i2a9.delivery.rocketcdn.me\/wp-content\/uploads\/2025\/04\/7239_1-300x200.jpg 300w, https:\/\/y7y6i2a9.delivery.rocketcdn.me\/wp-content\/uploads\/2025\/04\/7239_1-1024x683.jpg 1024w, https:\/\/y7y6i2a9.delivery.rocketcdn.me\/wp-content\/uploads\/2025\/04\/7239_1-768x512.jpg 768w, https:\/\/y7y6i2a9.delivery.rocketcdn.me\/wp-content\/uploads\/2025\/04\/7239_1-1536x1024.jpg 1536w, https:\/\/y7y6i2a9.delivery.rocketcdn.me\/wp-content\/uploads\/2025\/04\/7239_1-600x400.jpg 600w\" sizes=\"(max-width: 1920px) 100vw, 1920px\" data-ll-status=\"loaded\" data-lazy-src=\"https:\/\/y7y6i2a9.delivery.rocketcdn.me\/wp-content\/uploads\/2025\/04\/7239_1.jpg\" data-lazy-sizes=\"(max-width: 1920px) 100vw, 1920px\" data-lazy-srcset=\"https:\/\/y7y6i2a9.delivery.rocketcdn.me\/wp-content\/uploads\/2025\/04\/7239_1.jpg 1920w, https:\/\/y7y6i2a9.delivery.rocketcdn.me\/wp-content\/uploads\/2025\/04\/7239_1-300x200.jpg 300w, https:\/\/y7y6i2a9.delivery.rocketcdn.me\/wp-content\/uploads\/2025\/04\/7239_1-1024x683.jpg 1024w, https:\/\/y7y6i2a9.delivery.rocketcdn.me\/wp-content\/uploads\/2025\/04\/7239_1-768x512.jpg 768w, https:\/\/y7y6i2a9.delivery.rocketcdn.me\/wp-content\/uploads\/2025\/04\/7239_1-1536x1024.jpg 1536w, https:\/\/y7y6i2a9.delivery.rocketcdn.me\/wp-content\/uploads\/2025\/04\/7239_1-600x400.jpg 600w\" class=\"wp-image-30969 entered lazyloaded\" data-id=\"30969\" data-light-image=\"https:\/\/y7y6i2a9.delivery.rocketcdn.me\/wp-content\/uploads\/2025\/04\/7239_1.jpg\" data-full-image=\"https:\/\/y7y6i2a9.delivery.rocketcdn.me\/wp-content\/uploads\/2025\/04\/7239_1.jpg\" alt=\"\" height=\"1280\" width=\"1920\" src=\"https:\/\/y7y6i2a9.delivery.rocketcdn.me\/wp-content\/uploads\/2025\/04\/7239_1.jpg\" decoding=\"async\"\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/a\u003e\u003c\/figure\u003e\n\u003c\/div\u003e\n\u003cp\u003eThe 42mm 2-Row aluminum core is a massive improvement over the factory core.

The internal routing of the radiator forces the coolant to flow through the core three times (see diagram below), maximizing heat dissipation and resulting in lower coolant temperatures. This type of configuration ensures more even heat dissipation, reducing hotspots and promoting more consistent cooling.\u003c\/p\u003e\n\u003cdiv class=\"kadence-blocks-gallery-item-inner\"\u003e\n\u003cfigure class=\"kb-gallery-figure kb-gallery-item-has-link kadence-blocks-gallery-item-hide-caption\"\u003e\u003ca aria-label=\"Display this image in a lightbox\" class=\"kb-gallery-item-link\" href=\"https:\/\/y7y6i2a9.delivery.rocketcdn.me\/wp-content\/uploads\/2025\/04\/csf-triple-pass_1.jpg\"\u003e\n\u003cdiv class=\"kb-gal-image-radius\"\u003e\n\u003cdiv class=\"kb-gallery-image-contain kadence-blocks-gallery-intrinsic\"\u003e\u003cimg srcset=\"https:\/\/y7y6i2a9.delivery.rocketcdn.me\/wp-content\/uploads\/2025\/04\/csf-triple-pass_1.jpg 900w, https:\/\/y7y6i2a9.delivery.rocketcdn.me\/wp-content\/uploads\/2025\/04\/csf-triple-pass_1-300x200.jpg 300w, https:\/\/y7y6i2a9.delivery.rocketcdn.me\/wp-content\/uploads\/2025\/04\/csf-triple-pass_1-768x512.jpg 768w, https:\/\/y7y6i2a9.delivery.rocketcdn.me\/wp-content\/uploads\/2025\/04\/csf-triple-pass_1-600x400.jpg 600w\" sizes=\"(max-width: 900px) 100vw, 900px\" data-ll-status=\"loaded\" data-lazy-src=\"https:\/\/y7y6i2a9.delivery.rocketcdn.me\/wp-content\/uploads\/2025\/04\/csf-triple-pass_1.jpg\" data-lazy-sizes=\"(max-width: 900px) 100vw, 900px\" data-lazy-srcset=\"https:\/\/y7y6i2a9.delivery.rocketcdn.me\/wp-content\/uploads\/2025\/04\/csf-triple-pass_1.jpg 900w, https:\/\/y7y6i2a9.delivery.rocketcdn.me\/wp-content\/uploads\/2025\/04\/csf-triple-pass_1-300x200.jpg 300w, https:\/\/y7y6i2a9.delivery.rocketcdn.me\/wp-content\/uploads\/2025\/04\/csf-triple-pass_1-768x512.jpg 768w, https:\/\/y7y6i2a9.delivery.rocketcdn.me\/wp-content\/uploads\/2025\/04\/csf-triple-pass_1-600x400.jpg 600w\" class=\"wp-image-31011 entered lazyloaded\" data-id=\"31011\" data-light-image=\"https:\/\/y7y6i2a9.delivery.rocketcdn.me\/wp-content\/uploads\/2025\/04\/csf-triple-pass_1.jpg\" data-full-image=\"https:\/\/y7y6i2a9.delivery.rocketcdn.me\/wp-content\/uploads\/2025\/04\/csf-triple-pass_1.jpg\" alt=\"\" height=\"600\" width=\"900\" src=\"https:\/\/y7y6i2a9.delivery.rocketcdn.me\/wp-content\/uploads\/2025\/04\/csf-triple-pass_1.jpg\" decoding=\"async\"\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/a\u003e\u003c\/figure\u003e\n\u003c\/div\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"CSF","offers":[{"title":"Default Title","offer_id":47081221128444,"sku":"CSF7239","price":675.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1128\/7276\/files\/7239_1.jpg?v=1745357594","url":"https:\/\/jdcustomsusa.com\/ru\/products\/csf-16-18-ford-focus-rs-radiator","provider":"JD Customs U.S.A","version":"1.0","type":"link"}
