Looks great. I would like to know how much clearance there is from the back of the fan to the front of the engine?

What year E320?

Why did you switch to 170 degree themostat? I thought unleaded engines require 180 degree stats to help burn and effect fuel mileage.

I looked and looked for that connector, followed schematics and was still unable to locate the wire or right connector. Send pictures if you fins it.

I used the pre-wired air suspension relay location and 50 amp under hood fuse, I ran a 18 gauge wire to the inside and used a blank fuse location that was ignition on and a 15 amp fuse. I ran the fan ground wire to the battery.



Here is a link to the video showing the duty cycle of this fan and how quick it cools the coolant down. I just uploaded it a few minutes ago.

Driving around town was fine but this fan still had much less cooling capacity than the fan from an MBZ S600, even that fan wasn't enough for high engine loads. I think you are wasting your time and losing power by installing this.

FYI - CFD calcs on the factory fan are 10,000cfm. Have you done CFD for this fan or discovered its max CFM?
