CSF High Performance Aluminum Radiator BMW E39 M5 / 540i (MT)
$599.00
This radiator features a 2-Row core with CSF's exclusive B-Tube Technology: Unlike a regular oval shape "O" type radiator tube, CSF uses a specially engineered tube in the 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 aluminum material (with better cooling efficiency) because this design is actually stronger than normal "O" shape tubes that are welded. The design (inlet in the middle of the tube that is seam brazed) increases the heat transfer surface area of the tubes by approximately 15% over regular tubes - producing the efficiency of two smaller tubes vs. one large tube within the same space criteria. With "B-tubes" you are able to get "dual liquid laminar flow". CSF also 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 CSF E39 M5/540i radiator is a true "Drop-in fit" design requiring no modifications to install. OE style brackets are all CNC machined and welded for the best durability possible. Inlet/Outlet connections are designed to match the OE connections so you can reuse OEM hoses or aftermarket. Trust the cooling experts at CSF for the best performing, highest-quality, and most reliable radiators.
⚠ Fitment Notes
BMW 540i (E39) before 09/1998
The CSF #7064 comes with OE BMW quick connect radiator hose connections. Models with production dates before 09/1998 use slip on style hose connections. For this radiator to work on models produced before 09/1998 you will need to update the several parts. Most of which are standard replacements for cooling system maintenance.
The BMW OEM Parts Required for Retrofit:
- Water Pump: 11510393336
- Thermostat Housing: 11531436386
- Overflow Tank to Thermostat Hose: 11531711377
- Lower Radiator Hose: 11537505229
- Upper Radiator Hose*: 11537505228
*Upper radiator hose has a provision for the after 09/1998 alternator cooling. The before 09/1998 do not use this secondary hose so it will need to be capped off.

BMW 540i (E39) with Automatic Transmission (AT)
The radiator was designed for Manual Transmission, however, it can fit Automatic models produced before 09/1998 with no modifications and models produced after 09/1998 with minimal modification to drain plug.
AT 540i models produced after 09/1998 have a water-to-oil transmission cooler connected to the radiator on the Left Hand (LH) Side. To connect the factory transmission oil cooler to the CSF Radiator, you must replace the LH Drain Plug with a 3/8 - 18NPT threaded hose fitting. Please measure the inner diameter of your Radiator to Transmission Oil Cooler Regulator Valve hose to ensure you have the proper size hose fitting.
