Almost perfect
This is a great cooler for the right application, The hangers and clips that come with the kit are great for many types of setups for attaching the cooler to the front of the vehicle. the only part i feel is a huge let down is the amount of hose. The cooler itself is well made and cools very well. I recommend just go to the local parts store and get more 3/8s hose if needed.

Great product! Make sure get air movement over it. Used it for my transmission fluid.
This cooler has 2x the area of my stock cooler. On a "per square inch" basis, this one is easily 10~30% more efficient than my stock cooler. (Judging based on more and smaller plate channels, which spreads the fluid more. As well as turbulent fin design, which promotes heat exchange from cooler core into air. Truly a very well designed, well engineered product. ) I mounted mine at same location as factory stock cooler - inside the engine bay towards the driver side wheel. Reason: I am keeping front part of engine available for inter-cooler. In the back of engine, no fresh ram air. So I got a separate fan and mounted the two together. Fan runs on a thermostatic switch. I originally thought the switch needs to drive a relay, which then drives the fan (80W). But my mechanic skipped the ... This cooler has 2x the area of my stock cooler.

I originally thought the switch needs to drive a relay, which then drives the fan (80W). But my mechanic skipped the relay, and tied the thermostat switch directly to the fan. It works. I just don't know if prolonged operation (passing current) would overheat and cook the thermostat switch. Can't wait for outdoor temp to rise above 90F again, so I can really test how this combination runs.
