Racing and high performance radiators for all Porsche models make a great performance upgrade as well as an incredibly durable and reliable OE replacement.
Fits:
Porsche 944 2.5ltr / 2.7ltr - 1982 to 1989
Porsche 944S 16V 2.5ltr - 1988 to 1989
Porsche 944 S2 3.0ltr - 1989 to 1991
Porsche 944 turbo - 1985 to 1991
Please Note - for 1983 to 1985 manual cars, hose 94410624502 is required to fit this radiator
CSF has designed this radiator to fit all Porsche 944 models, normally aspirated (NA) and turbo and this High-Performance Radiator is a true plug-and-play “drop-in fit” upgrade.
All mounting brackets are CNC Machined for precise fitment and the cooling inlet/outlet connections use the same OEM style slip on connection type for use with any OEM or Aftermarket radiator hoses.
Now it fits normally aspirated and turbo models
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 taller than the non-turbo (NA) version. While designing the radiator, CSF decided to base the dimension off of the non turbo (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 models
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 have standard SPAL connectors but can be rewired for OEM connectors during installation.
- 2-Row – 42mm Ultra-High-Performance Core

8V ENGINE WITH AUTO ADJUSTER
Changing the water pump, pulley, and belts on an older Porsche 944 is essential for maintaining the car’s performance and preventing expensive repairs down the line. Here’s why:
1. Water Pump: The water pump is crucial for keeping the engine cool by circulating coolant throughout the system. Over time, the seals can wear out, and the pump itself can become less efficient or even fail completely. A failed water pump can cause the engine to overheat, leading to severe engine damage, which is costly to repair. Since the water pump is typically driven by the timing belt, replacing it during a timing belt service is a preventive measure.
2. Pulley: The pulleys, including the ones for the timing belt and accessory belts, can degrade over time due to wear and tear. If a pulley starts to fail, it can cause the belt to misalign or slip, which can lead to loss of power to critical systems like the water pump, alternator, or power steering. A worn-out pulley might also cause abnormal noises (like squealing) or vibrations, and in the worst case, it can lead to belt failure or further engine damage.
3. Belts: The timing belt and accessory belts (serpentine or V-belts) stretch and wear over time. A snapped timing belt can cause catastrophic engine damage, especially on interference engines like the 944’s. The accessory belts keep things like the alternator, air conditioning, and power steering working properly, and if they break, you’ll lose those functions—and possibly risk engine overheating if the water pump is driven by one of those belts.
4. Preventive Maintenance: On older cars, these parts have a limited lifespan, and replacing them as part of regular maintenance helps avoid major issues. The 944 is a well-built car, but its aging components need attention. Replacing the water pump, pulleys, and belts before they fail ensures your car runs smoothly and can help avoid the inconvenience and cost of unexpected breakdowns.
5. Improved Reliability: By proactively replacing these parts, you improve the overall reliability of your 944, ensuring that you can enjoy it without worrying about the engine overheating or being stranded due to a failed belt or pulley. In short, regular replacement of the water pump, pulleys, and belts is part of smart ownership for an older Porsche 944, helping preserve the engine’s health and longevity.

Porsche Engine Cooling Parts
Keeping your Porsche’s engine at the correct temperature is critical for both performance and reliability. At Design911, we supply a comprehensive range of engine cooling parts for every Porsche model — from classic air-cooled cars to the latest water-cooled performance machines.
Our collection includes everything from water and oil hoses to radiators, water pumps, oil coolers, thermostats, coolant tanks, and oil reservoirs — all at highly competitive prices. Whether you need a direct replacement for road use or a high-performance upgrade for track days, we have you covered.
What Porsche Engine Cooling Parts Are Available?
We stock a wide range of cooling system
components, including:
- Water Hoses & Oil Hoses – reliable replacements to keep fluids flowing under pressure
- Radiators – OE-spec replacements and high-performance race radiators
- Water Pumps & Oil Pumps – essential for maintaining correct circulation
- Oil Coolers – control oil temperature under high loads and spirited driving
- Thermostats – regulate engine operating temperatures
- Coolant Tanks & Oil Tanks – durable reservoirs designed to OEM standards
- Sensors & Switches – keep the cooling system responsive and efficient
We also supply premium engine oils and antifreeze/coolant — essential for year-round protection against freezing, overheating, and corrosion.
Why Engine Cooling is Essential
Your Porsche’s cooling system is the life support of the engine. Radiators, pumps, hoses, and coolers maintain safe operating temperatures and prevent catastrophic damage. A single failed component can lead to overheating, loss of oil pressure, or even engine failure.
That’s why it’s vital to maintain these parts and replace them promptly if you notice leaks, cracks, or performance issues.
Performance & Motorsport Cooling
Looking for more than just a replacement? Our race-spec radiators and oil coolers are engineered to deliver maximum cooling efficiency, helping you get the most out of your Porsche on the track. These high-performance systems handle extreme heat and stress, ensuring consistent results lap after lap.
How Often Should Engine Coolant Be Changed?
Coolant provides year-round protection against
both freezing and corrosion. On most Porsche models, coolant levels are checked
during regular servicing, and low levels will trigger a dashboard warning.
- Check coolant regularly and top up as needed.
- Replace coolant periodically according to Porsche’s service intervals.
- Always handle coolant with care - the reservoir is pressurised, and opening it when hot can cause burns. Allow the engine to cool before unscrewing the cap, cover it with a cloth, and open slowly to release pressure safely.
Why Choose Design911 for Cooling Parts?
- Huge Range – from OEM replacements to high-performance upgrades
- OEM & Aftermarket Options – trusted quality for every budget
- Worldwide Delivery – expertly packed to prevent damage in transit
- Customer Support – our Porsche specialists can help you select the right part for your model
