This radiator upgrade package for the 1999-4/2005 E46 323i/325i/328i/330i manual transmission cars includes a performance aluminum radiator and silicone hoses for bulletproof cooling and reliability. This is the perfect upgrade over a stock radiator with the radiator essentials - why spend more for a larger package when you only need the basics? This kit includes what you need when replacing the radiator -

  • CSF Aluminum radiator, #3305, replaces BMW 17119071518
  • BimmerWorld silicone upper radiator hose with connectors, replaces BMW 17127510952
  • BimmerWorld silicone lower radiator hose with connectors, #11531436408
  • Temp sensor, #13621433077
  • Radiator mounting bracket o-ring, #17111711987
There are other kits out there that include additional cooling system parts. But when you only need to replace the radiator, this is a more appropriate package. With these parts you only need to disconnect the minimum number of parts to swap out the radiator - each hose from the thermostat and the mounting plate from the radiator. The water pump, thermostat, and expansion tank all remain in place. We can also build you a custom package with a discount for any additional parts you need.

CSF Aluminum performance radiators feature a thicker core combined with their B-tube design to offer greatly enhanced cooling performance with improved durability. Instead of a single oval radiator tube, CSF has two tubes in the shape of a "B" that have more surface area and greater strength. In addition, CSF can use a thinner material that is more efficient and lighter. Adding lightness has its benefits as a thicker core will mean the radiator and extra coolant will weigh more (thicker is not always the best). By doing away with the plastic end tanks and connections, CSF has eliminated the main weak points of the stock radiator design. The plastic has a tendency to crack and leak, especially on track cars where the extreme heat makes the plastic brittle.

The BimmerWorld silicone hoses are a 3-layer polyester-core design which makes them much more durable than stock. They can hold more pressure and retain their flexibility longer without the aging and cracking issues of rubber hoses. This kit includes the two most common failure hoses - upper and lower radiator, and includes new OEM hose connectors. We don't recommend re-using the original connectors because the spring clip wears out over time and likely won't have adequate tension to seal on the new radiator. To prevent a leak post-install we have included new connectors in this package.

The o-ring in this package is for the mounting plate for the expansion tank. When removing the plate from the radiator this o-ring should be replaced.

BMW coolant is sold separately (or purchase it locally to save on shipping).

This package fits cars with manual transmission only.
