CSF VAG MQB ALL-ALUMINIUM TRIPLE PASS WATER RADIATOR

With the MQB platform able to generate huge amounts of power, with an output increase of almost 30% achievable with intakes, exhausts, intercooler and software an often overlooked area for improvement is the factory engine water cooling system. 

With such a substantial increase in output easily achievable it's easy to understand why the factory water radiator can struggle to exchange the heat from the engine and now exhaust gas heat from the integrated engine head exhaust manifold. It's not uncommon for these engines, whilst showing 90c on the coolant dial to actually be running in excess of 100c up to 110c during spirited driving when properly logged. 

Whatsmore is that during spirited driving, whilst the engine water coolant temp becomes high so does the engine oil. It's not uncommon for engine oil temperatures to spike to over 130c-145c during spirited driving and struggles to reduce without substantial time spent cooling the car down. This is due to there being no factory engine oil cooler, so the factory water radiator has a lot of work to do. 

Let's take a look at the stock cooler... 

The Stock Cooler:

- 1-row 26mm core

- single-pass

- 7mm fin height 

The stock cooler uses a single row, 26 mm core and is of a single pass design. This is a very thin core for this that does not make use of the available space efficiently which contributes to the cooling issues. After months of development, we have developed a solution which maximises the efficiency and of the space available whilst maintaining all of the factory mounting locations, hose locations etc for a direct replacement part, our specification is below... 

CSF's All-Aluminium Triple Pass Water Radiator

- 2-row 42mm B-tube core

- Triple-pass design

- 6.5mm fin height 

The CSF All-Aluminium Triple Pass Water Radiator utilises a 2-row 42mm core. Utilising all of the space between the condenser and radiator the core depth has been maximised and compatibility confirmed with large aftermarket intercoolers such as IE. The B-tube design maximises the tube efficiency in all areas, this tube design is stronger than 0-tubes less material can be used for a lighter more efficient heat transfer whilst surface area inside the tube is increased by 15% over 0-tubes. 

The Triple Pass design means coolant passes across the core three times before it exits maximising the time the radiator has to exchange heat for the coolest outlet temperature. Finally, the 6.5mm fin height has been wind tunnel optimised in CSF's in-house wind tunnel, leaving no stone unturned in the pursuit of the ultimate MQB Water Radiator solution.

CSF Cooling have over 50 years experience of designing and producing high quality, high performance cooling solutions for road and track. CSF manufactures the most advanced and efficient radiator cores in the industry by using innovative tube and fin technologies with industry leading testing methods to maximize airflow and heat dissipation. These techniques allow CSF to stay ahead of the pack when it comes to radiator technology:

B-Tube technology Unlike a regular oval shape O type radiator tube, CSF uses a specially engineered tube in a 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 aluminium material (giving better cooling efficiency) because this design is actually stronger than normal O shape tubes that are welded. The design of the inlet in the middle of tube that is seam brazed, increases the heat transfer surface area of the tubes by approximately 15% over regular tubes. You get the efficiency of 2 smaller tubes vs. 1 large tube within the same space criteria.

High Efficiency Multi Louvered Fin CSF 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 products from CSF also feature advanced end tank designs they offer two all-aluminum end-tank designs to match any style and performance need:

OE Radial Tanks Flat and rounded end-tanks that are welded together and finished with our 1 hour Show-Stopper mirror polish process. For the customer who likes the sleek and smooth look, and wants to display the intricate welding associated with this design (CSF 7000 series).

Deep Drawn Tanks The only high performance manufacture to feature this advanced radiator technology. These end-tanks are stamped to the same geometry of the applications original plastic end-tank. These tanks feature less welding, and are generally considered the strongest tank designs in the industry. Also finished with their Show-Stopper mirror polish.

CSF are an ISO 9001/9002 certified manufacturer, giving you the assurance that you are getting a top quality product every time.
