CSF Auxiliary Heat Exchanger, Audi 8V A3/S3 8S TTS and Volkswagen MkVII Golf R

Description

CSF is proud to announce the release of its highly anticipated MQB cooling components. Finally, an aftermarket high-performance cooling solution now available to tackle the many overheating issues that have plagued this otherwise great track-worthy platform. The Ultimate MQB cooling system, exclusively by CSF, is designed to keep engine water, as well as both transmission and engine oil temperatures in check and at optimal levels, even under the most demanding race conditions. By utilizing CSF’s new suite of coolers in either a 1,2, or 3 piece configuration, it allows drivers the ability to unleash their car’s full potential for extended periods during racing conditions.

The MQB platform consist of vehicles which have a unique cooling system in that all of the major engine and drivetrain fluids are water cooled (engine water, engine oil and transmission oil). For many of the higher ranging / highest performance models (Audi 8X S1, Audi 8V S3, Audi 8S TT (2.0TSi), Volkswagen MK7 Golf R, and 5F Leon Cupra) there are additional small radiators (heat exchangers) located at the corners of the front bumper underneath the headlights. Used on the left side of the vehicle as the DSG transmission heat exchanger, and on the right side as an auxiliary water radiator.

In these vehicles with 3 upfront water radiators (center (main radiator), left (DSG heat exchanger), and right (auxiliary water radiator)). The coolant flows from the engine into the main water radiator. The coolant then splits into a Y piece, going into two auxiliary heat exchangers (small radiators). The right side auxiliary radiator is dedicated solely as a secondary means of lowering coolant temperature to maximize efficiency. The left side auxiliary DSG heat exchanger cools the automatic transmission fluid that is contained in an oil-to-water transmission cooler.

For best performance to both engine temperatures and transmission performance, CSF recommends upgrading the main water radiator (CSF-7084), and the DSG heat exchanger (CSF-8132). For maximum performance, and heavy track use, CSF recommends upgrading the auxiliary radiator on the right side of the vehicle with an additional heat exchanger (CSF-8132).
