Why upgrade

An ideal upgrade for the brittle stock BMW radiator, the Mishimoto E30/E36 Performance Aluminum Radiator provides your vehicle with enhanced reliability and improved cooling efficiency. BMWs are known to have frequent cooling-related failures due to the use of numerous plastic components throughout the system. These kits are engineered around real chassis packaging, so hoses, coolers and adapters line up without fabrication on the listed years. Follow the published torque specs and install guide, reuse sensors where instructed, and confirm clearances if you run other supporting mods. Every unit ships with the Mishimoto Lifetime Warranty for as long as you own it.

Features

• Two-row, 1.57-inch thick brazed aluminum core provides ideal fluid temperatures on the street and track — a direct upgrade over the aging factory plastic-tank radiator.
• Functions with the stock mechanical fan and stock shrouding, and includes a threaded port for the factory temperature sensor — a bolt-in upgrade with no additional modification.
• Magnetic Drain Plug included to capture harmful metallic debris — no additional hardware needed for a complete install.
• Full aluminum construction with TIG-welded end tanks replaces the factory plastic-tank radiator that leaks and cracks after years of heat cycling.
