Forum Experts:

When replacing the fan temperature sensor (for the main fan) on my 1986 190E 2.3-16V, should I use an anti-seize material on the threads of the temperature sensor?? As you know, this sensor/switch is threaded into the head near the thermostat housing.

I have conflicting concerns about dissimilar materials (brass and aluminum) as well as heat transfer. Manuals do not cover this level of detail.

Thanks for any advice!
