Remember to drill a 1/8" hole in the thermostat just above the 'up arrow'.

Part of this mod is installing an 88 degree C thermostat and I did that.

There is a considerable amount of info on this mod over in the E36 forum. I went with the Zionsville piece because there was less fabrication and experimentation involved in getting it to work. Mishimoto also makes an electric fan and expansion tank for their radiators that will probably be a lower cost alternative. I am eliminating the clutch fan and the auxiliary fan. My install includes a Zionsville E36 aluminum shroud, expansion tank, and Spal electric fan. I have attached pictures of my solution using 2" x 2" aluminum angle from the local Home Depot. The E36 Mishimoto rests on the OEM radiator mount on the passenger side but is not wide enough to use the stock E34 mount on the driver's side. The one aspect that was not worked out yet, was how to securely mount the radiator on the driver's side. Along with providing an increased coolant capacity of 91%, this radiator improves heat dissipation, which is beneficial for both stock and modified applications. This X-Line Performance Aluminum Radiator reduces coolant temperature by 30 degrees Fahrenheit (16.62 degrees Celsius) and is 20% more efficient than the stock radiator. Most people overlook the importance of installing an upgraded radiator in their vehicle. Whether you have a daily-driven E36 M3 or an M20 spinning a large turbocharger, this radiator provides ideal temperatures on and off the track. A simple coolant leak can result in overheating, accelerated engine wear, or head gasket failure. BMWs are known to have frequent cooling-related failures due to the use of numerous plastic components throughout the system. An ideal upgrade for the brittle stock radiator, the Mishimoto E30/E36 X-Line Performance Aluminum Radiator provides your vehicle with enhanced reliability and improved cooling efficiency.
