This idea just struck me as I was reading another thread about the aux. coolers in MB 300's. My rig does not have an aux. cooler. For longevity of my 617 it might be a nice addition to have since my rig runs around 200F and on a hot day it will climb up to around 230F when plugging along up long hills on the highway.

Anyway, I can pull the aux. fan off a junker 300 MB sedan at a local yard. Is it a in front of radiator aux. fan or an in back of the radiator by the engine's fan. I don't recall off the top of my head. If it's an in front of radiator aux. fan then I have room for that on my beast so it would just mean I would have to build brackets to install it on the Unimog.

What all would you suggest I pull out of the junker for this?

How would I go about testing the parts pulled off the junker?

What temp sensor does this fan work off of? Same sensor as engine temp. gauge sensor?

When it comes to wiring the sensor up how would I swap it onto my 617 powered rig that does not have an aux fan?

I could hard wire it too I guess and just turn it on with a toggle switch. Would I need a solinoid for this? in fact... think even if I have a sensor I will want to wire in a togle so I can turn it or and alos off. Need an off for durring deep water forging. I've heard of the blades bending and slicing radiators when forging deep water.

Thanx in advance
George
