CSF Ultimate MQB cooling system

The VW Mk7 Golf R and GTI are two of the most widely praised and popular hot hatches globally and for good reason. Not only are they applauded for their factory performance, but respond extremely well to modifications. For instance, power can be increased by ~30% with simple bolt on upgrades such as an intake, exhaust, upgraded intercooler and off-the-shelf ECU software tuning. With the ability to increase the vehicle’s performance, it is often easy to overlook the consequence of increasing power, which equates to more heat being generated by the system. Combined with possible on-track / harsh driving conditions during race use, addressing the factory cooling system with CSF’s new line of MQB cooling products becomes increasingly necessary for optimal performance.

High Performance Aluminum Dual-Core Triple-Pass MQB Radiator and Optional DSG Heat exchangers

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.

Radiator

A high performance / race-grade, all-aluminum, triple-pass engine water radiator (CSF #7084)

Fitment

Audi 8V A3 1.8TSi, Audi 8V S3, Audi 8S TT (2.0TSi), Volkswagen MK7 Golf GTi, Volkswagen MK7 Golf R, Seat 5F Leon Cupra, Skoda 5E Octavia vRS

DSG/Heat Exchanger

A high performance / race-grade, all-aluminum, quadruple-pass DSG transmission water-to-oil heat exchanger. This new component is multi-fit that can also be installed (with no modifications) as an upgraded auxiliary radiator for maximum cooling performance. (CSF #8132)

CSF’s MQB cooling package
High performance all-aluminum, triple-pass engine water radiator (CSF #7084)
High performance all-aluminum, quadruple-pass DSG transmission water-to-oil heat exchanger (CSF #8132)

CSF’s triple-pass technology allows the coolant to flow through the radiator core 3x rather than just flowing across the surface of the core once. This allows cooler ambient air to exchange heat with the coolant for a longer period of time, generating the lowest outlet temperature possible.

Observations from driving:

Oil temperature seems to be consistently much lower by around 10-15°C (50-59°F), allowing me to use all of the revs all of the time without a care for oil temp. It sits at around 125°C (257°F) max now and I’ve never seen it go above 130°C (266°F) (this used to happen after around 2-3 “fast laps” with OEM set-up).

Oil temperature now peaks and flat lines throughout the sessions. Before it would slowly grow to around 130°C (266°F) and then rise uncontrollably, very quickly and then not be able to cool down. Every time you would jump back on the throttle to drive fast, the oil temperature would spiral out of control again (talking 14°C+ (284°F with EASE).

Observations from logs:

Engine coolant temperature does not go above 100.5°C (212.9°F)

What we can say for sure:

Engine Oil Temperatures are reduced and maintained consistently during full load/rpm

Engine coolant temperatures are maintained in the optimum range

DSG oil temperatures rises and falls in line with the engine coolant temperature (well within ideal operating parameters)

After installing the right hand side aux engine radiator (CSF #8132) to complete the Ultimate Cooling Solution for the MQB MK7 Golf R, results show that the coolant temperatures were maintained in optimal range (w/ peak @ 212°F) throughout the entire day regardless of the ambient and track temperatures. With this added cooling power, you now have the capability to track his Golf R in extreme conditions including longer and challenging race tracks without having to worry about cooling issues so there’s definitely more room to push the car to its limits.


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, Right (DSG/Aux radiators). 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 (#8132). For maximum performance, and heavy track use, CSF recommends upgrading the auxiliary radiator on the right side of the vehicle with an additional CSF #8132 heat exchanger.
