New CSF Porsche 944 (NA & Turbo) High Performance Radiator + Fan & Shroud Kit

[CSF Cooling]

CSF worked closely Joe Anselmo Motorsports in development and is pleased to release the High-Performance All Aluminum Radiator (CSF #7088) + Fan & Shroud Kit (CSF #8180) for the Porsche 944 (NA & Turbo).





Design & Engineering
Joe Anselmo Motorsports is one of the leading Porsche service centers here in Southern California and specializes in 944s. With Joe’s knowledge and expertise, CSF was able to design the radiator to fit all models of the Porsche 944. This High-Performance Radiator is a True Plug-and-Play “Drop-in Fit” upgrade.



All mounting brackets are CNC Machined for precise fitment. The cooling inlet/outlet connections use the same OEM style slip on connection type for use with any OEM or Aftermarket radiator hoses.

How it fits NA & Turbo
Many 944 owners know that the OEM Radiators for the NA and Turbo aren’t normally cross compatible without modifications. This is due the OEM Turbo radiator being ~1 inch taller than the NA version. While designing the radiator, CSF decided to base the dimension off of the NA radiator while increasing the core capacity to still exceed the OEM Turbo radiator’s cooling capacity. Using a 2-Row 42mm core with CSF’s Exclusive B-Tube Technology, the size difference is not a limiting factor in cooling performance. To remedy the size differential for installation, CSF includes CNC Billet spacers for use on the 944 Turbo (AKA 951).

Attention to Detail
CSF also included removable/adjustable crossover pipe brackets on the top of the radiator. The 944 Turbo model’s have a crossover cooling pipe while the NA version does not. This pipe is designed to distribute coolant from the reservoir to the radiator and from the coolant pump house to the cylinder head. From the factory, this pipe is normally zip tied to the top of the radiator to keep it from rattling around. Joe Anselmo thought this was a great addition to the radiator making the installation feel better than it came from the factory.

Upgrading the Fans
While the OEM Fans are functional, they are still a design dating back to the 1980’s and leave plenty of room for improvement. Electric fan technology has progressed a lot over the years and newer fans can efficiently move more air with a lower drawn on your car’s electrical system. The laser cut shroud ensures the most efficient function of the fans drawing air through the radiator. The low profile dual 9-inch SPAL fans move 1180 CFM of air. The Fan & Shroud kit is designed to fit the CSF #7088 Radiator but will also fit OEM 944 NA Radiators. These fans are pre-wired with OEM connectors for a quick plug and play installation.

Fitment includes the 944 S2 (3.0L). According to the OEM Cross Reference and our knowledge base these do not fit the 924 or 968.

if the old one is copper I imagine it would make a significant weight difference that some may like. Maybe they could add that difference to the specs?

Bummer, I was thinking for my 924S that we are swapping 968 running gear into

[J1NX3D]

I still use my standard single fan 944 radiator on my '86 with my 968 swap. I haven't converted to the Turbo radiator. I think this should still fit fine.

[Rasta Monsta]

I had SPAL fans on my 931. Worthy investment, significant upgrade.

However, not crazy about the "shroud" being a flat plate, and effectively blocking a substantial portion of the radiator. With just a tiny bit more effort on the shroud, the cooling efficiency would be significantly improved.

[originalowner]

It looks like the shroud blocks a substantial portion of the airflow through a large portion of the radiator. I believe CSF (and more importantly, their customers,) would be well served if they would skeletonize the shroud, allowing the fans to pull through the portion they currently do for low speed operation, and allow free flow through the entire radiator for high speed operation. Just my humble opinion, of course. Always glad to see aftermarket support for our little toys.

[Monkey Wrench]

perhaps it's a trade off, the fan may move more air through the rad with that plate in place, Thats probably why it's there, but if the fan isn't operating until it gets switched on by the thermostat , maybe it would switch on earlier with the airflow being limited by the flat plate. perhaps it has a faster warmup time by blocking flow like that?
my 67 volvo 122 ,(AKA a Volvo Canadian) had a radiator blind with a chain you pull from the inside so you could warm up your car in cold climates. It was designed by swedes who see colder winter temps than in Germany.

Common practice for those who live in cold areas is to use a chunk of cardboard and block part of the rad. If it's cold out you want the rad to get warm so you can have adequate heat and defrost capabilities. some add block heaters to heat the oil or water to get them going when its cold out.

if you only envision the car going down the highway the fan probably isn't even necessary as you have airflow. in that case yes not having the flat plate might offer more cooling. In that state the fan might be operating but basically being driven by wind as well. Then if you go up a steep hill you may go slower but require more power, and need the cooling and so the fan is needed.
When you stop in traffic it would be a concern pretty quickly without the fan, so it's necessary.

perhaps the requirements are a bit different for someone out in the country that doesn't do city driving as compared to a person living in the city, and same for people living in different climates, but the rad design needs to encompass all driving conditions.

more fans or bigger fans mean more work for the alternator and that uses more fuel. when the battery has no demand to be charged, then the alternator doesn't put as much load on the engine via the drive belt.

i suppose one could engineer things so the fan wasn't powered when not needed or things like flaps could open when driving faster to take advantage of the airflow already available by wind, but of course that would add more complication with very little fuel savings.

the temperature switch is a bit of a tradeoff as it will reduce the reliance on the alternator slightly if it doesn't run when the engine isn't warm yet. It also doesn't do the engine any good to be taking longer to warm up to operating temp. lots of cars did not have electric cooling fans so they are pumping air over the rad when whats actually desirable would be for no or little airflow to allow the engine to reach operating temp faster. some have a clutch on the fan or some add fans with flex blades to reduce unnecessary load.

If you made holes or removed that flat plate it might improve flow on the highway, but then on a cold day it may also take longer for your engine to get up to operating temp. someone in Arizona might have different driving situations compared to someone in Alaska. Racers of course would have completely different requirements of the cooling system.

cold winter driving conditions may be less of a concern for many as it's a sports car, they may garage their cars in winter , It might not be the best choice of vehicle if you are living in a very cold climate, low ground clearance so not great in the snow. all the same , some do need their cars to work right at low temps in winter too. cold doesn't necessarily mean snow.

[Rasta Monsta]

It just needs to be a box instead of a plate.

[CSF Cooling]

Fan shroud has been optimized on our wind-tunnel for normal driving use + race car use - due diligence has been done - this is a legit set-up for all types of 944's

let us know if you have any other questions - we're happy to be able to support the growing 944 community with a high performance alternative to the no longer available OEM unit.

[Rasta Monsta]

"Wind tunnel optimization" resulted in a flat plate with two holes in it?

C'mon man. I was born at night, but it wasn't last night.

A couple of summers ago I did a stint at Scott Base in Antarctica. McMurdo station was just over the hill from us. The USAP blocked off their radiators but we didn't on our landcruisers but you'll note some of the ducting was blocked. All vehicles had block heaters, most had webasto diesel heaters. It does get warm enough at the peak of summer that neither have to be used unless some bad weather rolls in.

i had an old 63 international scout with really no compression, and drove that in the interior of BC during the winter. Id drain the rad and take the rad water and battery in the house and the battery. In the morning I'd put the warm oil in and the battery warm from being in the house and dump in the warm rad water. back then it would go to about -40 but Haven't seen anything near that since I was a kid. I think - 40 is the same in C or F driving gets dangerous because if your engine dies you can freeze pretty fast You have to dress for that possibility.. It must be a lot colder and more serious in Antartica.
