Just curious about a few things.

I am running the stock e36 ('92 325is) tstat which I think is around 88c? And as for the radiators aux fan switch, it's running one from a 325e (yet the radiator is from a 89 325i). So, my main question is, where should the temp gauge comfortably sit? If you're looking at the temp gauge, on the left its the blue, then there's that small line, and then you're at half way, ect down to the red, on the right. Mine has been sitting from the top of the blue, to the line right after it.

Should I run a lower tstat? I'm running a 16" 1500cfm pusher fan (no fan attached to the motor) mounted in front of the radiator that I can turn on from in the car. I'd just like to know where (with my set up, minus the electric fan) my temp gauge SHOULD sit, and when I should turn on the fan.

Maybe I'm getting paranoid, but I'd rather be safe than sorry and NOT have my car overheat. Ugh, what a nightmare.

EDIT: M50nv.

Stock t-stat should be fine because it matches the engine well. You may want to swap the temp switch on the radiator for the 80/88C one though. You can get this from a 318 E36.

I have the 80° stat and switch, very happy with the improvement.
I run a tad under half way, half way in traffic and if needed low speed fan goes on.
I turn on high speed fan manually sometimes just for the hell of it.
No viscous fan on mine.

Anyone know what 1/2 equals for real temperature? 80 C?
