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!

BMW E36 Aluminum Coolant Expansion Tank!

Historically, BMW vehicles have been plagued with rather frequent cooling system failures. A majority of these failures are a result of the use of plastic components in a high-temperature application. Although failure isn't immediate, over time the frequent heat cycling of these plastic components results in increased fragility, fatigue, and eventual failure.

A few components we see failing on E36 models include the radiator end tanks, radiator expansion tank, and the mechanical fan. We already offer two aluminum radiator options, and we have an electric-fan conversion kit in the works. An expansion tank is our last stop for product development on the E36 (for now). We have had numerous requests

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

The testing results are in! First, a quick comparison of the fluid capacity improvements the Mishimoto X-line radiator provides.

Stock Radiator Capacity: 0.6 gal (2.27L)

Mishimoto X-Line Radiator Capacity: 1.15 gal (4.35L)

This is an increase in capacity of 91%! This additional fluid, combined with our highly efficient core design, should easily produce great gains in cooling efficiency. Let's evaluate our charts obtained from the testing data. First up, our raw temperature data from both rounds of testing.

Being pleased with our design in comparison to the stock unit, it was time to put this radiator to the test and see how the improvements would impact cooling efficiency. The first true test for this radiator would be fitment. Although this product was designed based off of dimensions from the stock radiator and the engine bay of an E36 M, we still had yet to drop this unit into a vehicle to ensure that all components bolted into position properly. We snagged the keys to our test vehicle from our videographer and easily dropped our prototype into place. Check out a few shots of this radiator installed!

Alright, the prototype is in and ready for comparison against the stock unit. To show how much different this radiator is compared to our current offering, we would also be bringing in one of these radiators to observe the differences. First, let's take a look at the stock radiator we have. This unit was used to pull critical fitment dimensions.

Mishimoto BMW E30/E36 X-Line Performance Aluminum Radiator

Mishimoto is well known for providing innovative products for vehicles new and old. Our last few months have been dedicated to product development for the new 2015 Subaru WRX, which features a vast amount of changes from the previous generation. Along with these projects, we decided to go back to an older chassis and develop a brand new product for the E30/E36 BMW. We are huge BMW enthusiasts here, myself included, and we have found a gap in the radiator options for the late model E30 and E36 models. We have had great success with our current performance aluminum radiator for the E36. Our current offering is a perfect option for those who need an upgrade in the reliability department. The factory radiator is extremely prone
