Our final prototype is complete and looks fantastic. The fan mount is constructed from 1/8" steel that has been cut to a specific shape allowing for additional airflow through the radiator core at speed. Additionally, the mount is powder coated black to provide a durable finish. As noted in our last post, we tested this unit extensively with our 16" fan to ensure that coolant temperatures were properly regulated during both idle and all driving conditions.
Check out a few shots of the mount!

This shroud has been designed to function with the stock expansion tank as well as the aluminum expansion tank we have been working to develop. Check out the mounting system our engineering team designed to secure the tank properly in the stock location.

First Prototype Testing
When we left off last time we were exploring our first prototype design. This unit is a traditional aluminum fan shroud with air flaps to improve core airflow at speed. Once we had a working prototype, we decided to perform some idle testing to see how well our single electric fan would perform on a mostly stock E36 M3.
To get started, we began removing the stock setup.

Next, we installed the Mishimoto prototype along with our temperature sensors for data collection.

Our goal with this particular testing was to ensure that our fan could control and properly regulate idle temperatures for an extended time. We positioned the vehicle on the dyno, adjusted the fan controller, and kept an eye on the gauges.

E36 M3 test vehicle
Cooling systems on older BMW models have been recognized as a frequent failure point requiring regular replacement to avoid catastrophic failure. This includes anything made of plastic within the system. So far we have a few remedies - an aluminum radiator and a silicone coolant hose kit. The mechanical fan is next on our list to be addressed.
The stock fan setup is certainly efficient in keeping your straight six cool. That said, a fan failure can get quite ugly with shrapnel tossed around the engine bay, often damaging other components. To reduce vehicle downtime and expense, it would be wise to replace this component before failure occurs.
Swapping your antiquated mechanical setup for an efficient electric system is a great way to improve reliability, and even free up some power on your vehicle. Check out the process
