Continuing with our progress last time, we were set on constructing a prototype bracket so that we could fully install our system and collect some on-road data.
Cooler Bracket Fabrication
When we left you our team had selected an appropriate cooler location and had started making a bracket template for the heat exchanger. Once we had a general idea of the size, bends, and hole location, we started making a bracket from plate steel.

A couple of bends were needed to properly locate our mounting points!

Additional measurements were taken, and the bracket was trimmed to its final shape.

The four holes on this mounting bracket attach directly to the oil heat exchanger.
Next, we mounted this into position on the car!

Auxiliary Bracket
Although this bracket provided reasonable rigidity for the cooler, we wanted to add an auxiliary bracket to the base of the cooler for additional strength. We followed a similar process to fabricate this component!

A few welds and we had our second bracket complete!

Sandwich Plate and Line Route
To complete our kit we would need to install our sandwich plate and oil lines. First, the oil filter is removed.

We then installed our thermostatic sandwich plate and routed our lines.

We are placing the lines behind the crash beam to conceal them from view once fully installed.
