CSF All-Aluminum High-Performance Radiator for BMW E39 M5 & 540i – Part #7064

Description

The CSF #7064 high-performance all-aluminum radiator is specifically engineered for optimal cooling of BMW E39 M5 and 540i models from 1995 to 2003. Built with over five decades of expertise, CSF’s radiator combines innovative design and advanced manufacturing to deliver superior heat dissipation whether on the street or at the track. Its 2-row core with CSF’s exclusive B-Tube technology ensures enhanced durability and cooling efficiency, making it ideal for high horsepower builds and motorsports environments. The B-tube design, with its carefully formed and brazed “B” shape, increases heat transfer surface area by approximately 15% compared to traditional oval tubes, resulting in improved thermal performance. This design also enables dual liquid laminar flow, which improves coolant flow and heat rejection.
The radiator features ultra-efficient multi-louvered fins with a fin height of 6.5mm, precisely aligned to maximize airflow and heat dissipation. Each fin and tube combination is tested in CSF’s wind-tunnel laboratory to ensure maximum efficiency and consistent performance. The radiator is designed as a direct, drop-in replacement that installs in the OEM location without modifications, accepting all factory components including quick-connect hoses, brackets, and fan shrouds. CNC machined brackets and fittings provide a precise fit and long-lasting durability, while the all-aluminum construction ensures a lightweight yet robust component. The inclusion of a race-style drain plug and a smooth satin finish enhances both functionality and aesthetic appeal.
This radiator guarantees easy installation with minimal effort, adhering to OEM specifications. It’s highly recommended to have the installation performed by a qualified technician if you’re uncertain about the procedure. Whether for daily driving, high-performance applications, or racing, the CSF #7064 radiator is an essential upgrade to maintain optimal engine temperatures and improve overall vehicle reliability. Designed to fit multiple BMW models, this radiator is a proven choice for enthusiasts seeking maximum cooling efficiency combined with durable, race-grade construction.
