Job done, pics will follow shortly.
Getting the fan clutch off was impossible, it wouldn't give. We broke the shroud intentionally, removed the radiator for room, pulled everything as a unit and used a torch to separate.
I used a new Bosch high flow water pump as i am anal about doing things right lol.
Refill with G12+ coolant and good.
Pcmforless battery cables are a seriously recommended upgrade by me dear God are they effective and handle the fan well.
We wired the efsn into the controller, used a 30a fusable breaker, made sure it was pulling not pushing and mounted the controller to the excess plastic on the washer bottle.
Use an ice pick to wallow holes through the radiator fins for the mounts and probe.
I noticed that our fan engages by setting the controller all the way to the left and slightly right from there, it kicks on during excessive idling but not highway, no overheating, brings temps down within 20 secs.
Excellent mod, Definite power increase and easier revving, not hard to do just be intelligent at wiring.
