BMW E30/E36 (88-99) Mishimoto X-Line aluminium radiator

The Mishimoto X-Line radiator E36 is a heavy-duty three-row aluminium radiator for the BMW 3 Series E36 and the late six-cylinder E30. It replaces the brittle original radiator with plastic end tanks, a well-known cause of leaks and overheating on these BMWs.

According to Mishimoto’s testing, this radiator is 20 percent more efficient than stock and lowers coolant temperatures by about 16.6 °C. The core is 73 percent thicker and the capacity is 91 percent larger. Ideal for an E36 that works hard on track or in drifting, or for an E30 with a tuned or boosted M20.

Installation and delivery

The X-Line radiator fits in the original location. Mishimoto rates the installation as medium. Note: the original E30 fan shroud does not fit, and with a European oil cooler you need conversion brackets. For automatic cars, threaded provisions for the transmission cooler are present. After installation, fill the system with good quality coolant and bleed it carefully. The Mishimoto installation guide and engineering report are available below. Lead time: 4 to 7 days.

Three rows of aluminium, 91 percent more coolant and up to 16.6 °C cooler: the end of the brittle original BMW radiator.

Why choose this Mishimoto X-Line radiator E36?

With three rows, the X-Line is a clear step up from a standard performance radiator. Where the original radiator with plastic tanks cracks over the years, this one is full aluminium and TIG-welded. The extra row and thicker core give you reserve for long sessions, hot days and tuned engines. With Mishimoto’s lifetime warranty, you only buy it once.
