My 190D hasn't had a working cooling fan in ~3 years, the electromagnetic fan
clutch quit and I haven't wanted to spend the $400 to replace it... I hope the
one in the parts car works...
The only time its ever been a problem is idling in traffic, I usually just turn
on the heat and open the window.

No. What you need is to cure the slop/leakage in
the system, not change the set point of the regulator.

Or remove the fan altogether (in the winter) on these 200
series engines. Bet it isn't needed! Then use just the
right amount of cardboard and worry not about fan fatigue.

You mean like the thermostatically-controlled 'shark gill'
vents in the lower engine compartment of my SDL?
